202-600: The Trans-Alaska Pipeline System ( TAPS ) is an oil transportation system spanning Alaska, including the trans-Alaska crude-oil pipeline , 12 pump stations , several hundred miles of feeder pipelines, and the Valdez Marine Terminal. TAPS is one of the world's largest pipeline systems. The core pipeline itself, which is commonly called the Alaska pipeline , trans-Alaska pipeline , or Alyeska pipeline , (or The pipeline as referred to by Alaskan residents),
404-523: A Bosnian Serb named Gavrilo Princip assassinated Archduke Franz Ferdinand , heir to the Austro-Hungarian throne. Austria-Hungary held Serbia responsible, and declared war on 28 July. After Russia mobilised in Serbia's defence, Germany declared war on Russia and France , who had an alliance . The United Kingdom entered after Germany invaded Belgium , whose neutrality it guaranteed, and
606-645: A blue-water navy was vital for global power projection; Tirpitz had his books translated into German, while Wilhelm made them required reading for his advisors and senior military personnel. However, it was also an emotional decision, driven by Wilhelm's simultaneous admiration for the Royal Navy and desire to surpass it. Bismarck thought that the British would not interfere in Europe, as long as its maritime supremacy remained secure, but his dismissal in 1890 led to
808-592: A boomtown atmosphere in Valdez , Fairbanks , and Anchorage . The first barrel of oil traveled through the pipeline in the summer of 1977, with full-scale production by the end of the year. Several notable incidents of oil leakage have occurred since, including those caused by sabotage, maintenance failures, and bullet holes. As of 2015, it had shipped over 17 billion barrels (2.7 × 10 m) of oil. The pipeline has been shown capable of delivering over two million barrels of oil per day but nowadays usually operates at
1010-592: A grenade at the Archduke's car and injured two of his aides. The other assassins were also unsuccessful. An hour later, as Ferdinand was returning from visiting the injured officers in hospital, his car took a wrong turn into a street where Gavrilo Princip was standing. He fired two pistol shots, fatally wounding Ferdinand and his wife Sophie . According to historian Zbyněk Zeman , in Vienna "the event almost failed to make any impression whatsoever. On 28 and 29 June,
1212-540: A guerrilla warfare campaign and only surrendered two weeks after the armistice took effect in Europe. Before the war, Germany had attempted to use Indian nationalism and pan-Islamism to its advantage, a policy continued post-1914 by instigating uprisings in India , while the Niedermayer–Hentig Expedition urged Afghanistan to join the war on the side of Central Powers. However, contrary to British fears of
1414-677: A $ 100 million contract for more than 800 miles (1280 km) of pipeline. At the same time, TAPS placed a $ 30 million order for the first of the enormous pumps that would be needed to push the oil through the pipeline. In June 1969, as the SS Manhattan traveled through the Northwest Passage, TAPS formally applied to the Interior Department for a permit to build an oil pipeline across 800 miles (1,300 km) of public land—from Prudhoe Bay to Valdez. The application
1616-408: A change in policy and an Anglo-German naval arms race began. Despite the vast sums spent by Tirpitz, the launch of HMS Dreadnought in 1906 gave the British a technological advantage. Ultimately, the race diverted huge resources into creating a German navy large enough to antagonise Britain, but not defeat it; in 1911, Chancellor Theobald von Bethmann Hollweg acknowledged defeat, leading to
1818-613: A direct threat. The 1908–1909 Bosnian Crisis began when Austria annexed the former Ottoman territory of Bosnia and Herzegovina , which it had occupied since 1878. Timed to coincide with the Bulgarian Declaration of Independence from the Ottoman Empire, this unilateral action was denounced by the European powers, but accepted as there was no consensus on how to resolve the situation. Some historians see this as
2020-526: A discovery well. On March 12, 1968, an Atlantic Richfield drilling crew hit paydirt. A discovery well began flowing at the rate of 1,152 barrels (183.2 m) of oil per day. On June 25, ARCO announced that a second discovery well likewise was producing oil at a similar rate. Together, the two wells confirmed the existence of the Prudhoe Bay Oil Field . The new field contained more than 25 billion barrels (4.0 × 10 ^ m) of oil, making it
2222-483: A federal right-of-way for the pipeline and transportation highway was granted on January 3, 1974. The deal was signed by the oil companies on January 23, allowing work to start. Although the legal right-of-way was cleared by January 1974, cold weather, the need to hire workers, and construction of the Dalton Highway meant work on the pipeline itself did not begin until March. Between 1974 and July 28, 1977, when

Young found that by slow distillation he could obtain several useful liquids from it, one of which he named "paraffine oil" because at low temperatures it congealed into a substance resembling paraffin wax. The production of these oils and solid paraffin wax from coal formed the subject of his patent dated October 17, 1850. In 1850, Young & Meldrum and Edward William Binney entered into partnership under
2626-527: A fraction of maximum capacity. If flow were to stop or throughput were too little, the line could freeze. The pipeline could be extended and used to transport oil produced from controversial proposed drilling projects in the nearby Arctic National Wildlife Refuge (ANWR). Iñupiat people on the North Slope of Alaska had mined oil-saturated peat for possibly thousands of years, using it as fuel for heat and light. Whalers who stayed at Point Barrow saw
2828-471: A gap between the German armies as they closed on Paris. The French army, reinforced by the British expeditionary corps, seized this opportunity to counter-attack and pushed the German army 40 to 80 km back. Both armies were then so exhausted that no decisive move could be implemented, so they settled in trenches, with the vain hope of breaking through as soon as they could build local superiority. In 1911,
3030-574: A legal dispute over pipeline tariffs generated a one-time payment of more than $ 1.5 billion from the oil companies. The Constitutional Budget reserve is run similar to the Permanent Fund, but money from it can be withdrawn to pay for the state's annual budget, unlike the Permanent Fund. Although the Trans-Alaska Pipeline System began pumping oil in 1977, it did not have a major immediate impact on global oil prices. This
3232-512: A much shallower level. The Athabasca oil sands are one example of this. An alternative mechanism to the one described above was proposed by Russian scientists in the mid-1850s, the hypothesis of abiogenic petroleum origin (petroleum formed by inorganic means), but this is contradicted by geological and geochemical evidence. Abiogenic sources of oil have been found, but never in commercially profitable amounts. "The controversy isn't over whether abiogenic oil reserves exist," said Larry Nation of
3434-486: A port at Prudhoe Bay, and more—were deemed to pose more environmental risks than construction of a pipeline directly across Alaska. Opposition also was directed at the building of the construction and maintenance highway parallel to the pipeline. Although a clause in Alyeska's pipeline proposal called for removal of the pipeline at a certain point, no such provision was made for removal of the road. Sydney Howe, president of
3636-548: A possibility. This was accentuated by British and Russian support for France against Germany during the 1911 Agadir Crisis . German economic and industrial strength continued to expand rapidly post-1871. Backed by Wilhelm II, Admiral Alfred von Tirpitz sought to use this growth to build an Imperial German Navy , that could compete with the British Royal Navy . This policy was based on the work of US naval author Alfred Thayer Mahan , who argued that possession of
3838-476: A process known as catagenesis . Formation of petroleum occurs from hydrocarbon pyrolysis in a variety of mainly endothermic reactions at high temperatures or pressures, or both. These phases are described in detail below. In the absence of plentiful oxygen, aerobic bacteria were prevented from decaying the organic matter after it was buried under a layer of sediment or water. However, anaerobic bacteria were able to reduce sulfates and nitrates among
4040-834: A revolt in India, the outbreak of the war saw a reduction in nationalist activity. Leaders from the Indian National Congress and other groups believed support for the British war effort would hasten Indian Home Rule , a promise allegedly made explicit in 1917 by Edwin Montagu , the Secretary of State for India . In 1914, the British Indian Army was larger than the British Army itself, and between 1914 and 1918 an estimated 1.3 million Indian soldiers and labourers served in Europe, Africa, and

First World War World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War , was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers . Fighting took place mainly in Europe and

The production stopped in 1963, but Wietze has hosted a Petroleum Museum since 1970. Oil sands have been mined since the 18th century. In Wietze in lower Saxony, natural asphalt/bitumen has been explored since the 18th century. Both in Pechelbronn as in Wietze,

Tensions increased after the 1911–1912 Italo-Turkish War demonstrated Ottoman weakness and led to the formation of the Balkan League , an alliance of Serbia, Bulgaria, Montenegro , and Greece . The League quickly overran most of
4848-649: A solution to the problem, and President Richard Nixon began lobbying for the Trans-Alaska Pipeline as at least a part of the answer. Nixon supported the pipeline project even before the oil crisis. On September 10, 1973, he released a message stating that the pipeline was his priority for the remainder of the Congressional session that year. On November 8, after the embargo had been in place for three weeks, he reaffirmed that statement. Members of Congress, under pressure from their constituents, created
5050-574: A source of internal and inter-state conflict, leading to both state-led wars and other resource conflicts . Production of petroleum is estimated to reach peak oil before 2035 as global economies lower dependencies on petroleum as part of climate change mitigation and a transition towards renewable energy and electrification . The word petroleum comes from Medieval Latin petroleum (literally 'rock oil'), which comes from Latin petra 'rock' (from Greek pétra πέτρα ) and oleum 'oil' (from Greek élaion ἔλαιον ). The origin of
5252-587: A two pronged survey using bush aircraft , local Inupiat guides, and personnel from multiple agencies to locate reported seeps. Ebbley and Joesting reported on these initial forays in 1943. Starting in 1944, the U.S. Navy funded oil exploration near Umiat Mountain , on the Colville River in the foothills of the Brooks Range . Surveyors from the U.S. Geological Survey spread across the petroleum reserve and worked to determine its extent until 1953, when

Otherwise, the bulk of the liquid and solids are largely heavier organic compounds, often hydrocarbons (C and H only). The proportion of light hydrocarbons in the petroleum mixture varies among oil fields . An oil well produces predominantly crude oil. Because the pressure
5656-526: A visit to Fort Duquesne in 1750. Early British explorers to Myanmar documented a flourishing oil extraction industry based in Yenangyaung that, in 1795, had hundreds of hand-dug wells under production. Merkwiller-Pechelbronn is said to be the first European site where petroleum has been explored and used. The still active Erdpechquelle, a spring where petroleum appears mixed with water has been used since 1498, notably for medical purposes. There
5858-478: A war on two fronts; the Schlieffen Plan envisaged using 80% of the army to defeat France, then switching to Russia. Since this required them to move quickly, mobilization orders were issued that afternoon. Once the German ultimatum to Russia expired on the morning of 1 August, the two countries were at war. At a meeting on 29 July, the British cabinet had narrowly decided its obligations to Belgium under
6060-402: A weak Ottoman government, rather than an ambitious Slav power like Bulgaria . Russia had ambitions in northeastern Anatolia while its clients had overlapping claims in the Balkans. These competing interests divided Russian policy-makers and added to regional instability. Austrian statesmen viewed the Balkans as essential for the continued existence of their Empire and saw Serbian expansion as
6262-455: A whole, the Somme offensive led to an estimated 420,000 British casualties, along with 200,000 French and 500,000 Germans. The diseases that emerged in the trenches were a major killer on both sides. The living conditions led to disease and infection, such as trench foot , lice , typhus , trench fever , and the ' Spanish flu '. At the start of the war, German cruisers were scattered across

The discovery at Oil Springs touched off an oil boom which brought hundreds of speculators and workers to the area. Advances in drilling continued into 1862 when local driller Shaw reached a depth of 62 metres using the spring-pole drilling method. On January 16, 1862, after an explosion of natural gas , Canada's first oil gusher came into production, shooting into

The crude oil pipeline is privately owned by the Alyeska Pipeline Service Company . Oil was first discovered in Prudhoe Bay in 1968 and the 800 miles of 48" steel pipe was ordered from Japan in 1969 (U.S. steel manufacturers did not have
6868-491: Is called diagenesis , a word that means a transformation of materials by dissolution and recombination of their constituents. Kerogen formation continued to a depth of about 1 km from the Earth's surface where temperatures may reach around 50 °C . Kerogen formation represents a halfway point between organic matter and fossil fuels : kerogen can be exposed to oxygen, oxidize and thus be lost, or it could be buried deeper inside
7070-726: Is considered a sticky, black, tar-like form of crude oil which is so thick and heavy that it must be heated or diluted before it will flow. Venezuela also has large amounts of oil in the Orinoco oil sands , although the hydrocarbons trapped in them are more fluid than in Canada and are usually called extra heavy oil . These oil sands resources are called unconventional oil to distinguish them from oil which can be extracted using traditional oil well methods. Between them, Canada and Venezuela contain an estimated 3.6 trillion barrels (570 × 10 ^ m ) of bitumen and extra-heavy oil, about twice
7272-738: Is done after a study of the relevant structural geology , analysis of the sedimentary basin , and characterization of the petroleum reservoir . There are also unconventional reserves such as oil sands and oil shale which are recovered by other means such as fracking . Once extracted, oil is refined and separated, most easily by distillation , into innumerable products for direct use or use in manufacturing. Products include fuels such as gasoline (petrol), diesel , kerosene and jet fuel ; asphalt and lubricants ; chemical reagents used to make plastics ; solvents , textiles , refrigerants , paint , synthetic rubber , fertilizers , pesticides , pharmaceuticals , and thousands of others. Petroleum

A gas well produces predominantly natural gas . However, because the underground temperature is higher than at the surface, the gas may contain heavier hydrocarbons such as pentane, hexane , and heptane (" natural-gas condensate ", often shortened to condensate. ) Condensate resembles gasoline in appearance and
7878-756: Is now called the Drake Well in Cherrytree Township, Pennsylvania .There also was a company associated with it, and it sparked a major oil drilling boom. The first commercial oil well in Canada became operational in 1858 at Oil Springs, Ontario (then Canada West ). Businessman James Miller Williams dug several wells between 1855 and 1858 before discovering a rich reserve of oil four metres below ground. Williams extracted 1.5 million litres of crude oil by 1860, refining much of it into kerosene lamp oil. Williams's well became commercially viable
8080-438: Is partly because it took several years to reach full production and partly because U.S. production outside Alaska declined until the mid-1980s. The Iranian Revolution and OPEC price increases triggered the 1979 energy crisis despite TAPS production increases. Oil prices remained high until the late 1980s, when a stable international situation, the removal of price controls, and the peak of production at Prudhoe Bay contributed to

In October 1914, the Canadian magazine Maclean's similarly wrote, "Some wars name themselves. This is the Great War." Contemporary Europeans also referred to it as " the war to end war " and it was also described as "the war to end all wars" due to their perception of its unparalleled scale, devastation, and loss of life. The first recorded use of
9090-640: The 1980s oil glut . In 1988, TAPS was delivering 25 percent of all U.S. oil production. As North Slope oil production declined, so did TAPS's share of U.S. production. Today, TAPS provides less than 17 percent of U.S. oil production. Petroleum Petroleum is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons , and is found in geological formations . The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.

The latter happened through catagenesis in which the reactions were mostly radical rearrangements of kerogen. These reactions took thousands to millions of years and no external reactants were involved. Due to the radical nature of these reactions, kerogen reacted towards two classes of products: those with low H/C ratio ( anthracene or products similar to it) and those with high H/C ratio ( methane or products similar to it); i.e., carbon-rich or hydrogen-rich products.

Because the United States imported approximately 35 percent of its oil from foreign sources, the embargo had a major effect. The price of gasoline shot upward, gasoline shortages were common, and rationing was considered. Most Americans began demanding
10100-490: The Orinoco Belt . While significant volumes of oil are extracted from oil sands, particularly in Canada, logistical and technical hurdles remain, as oil extraction requires large amounts of heat and water, making its net energy content quite low relative to conventional crude oil. Thus, Canada's oil sands are not expected to provide more than a few million barrels per day in the foreseeable future. Petroleum consists of
10302-721: The Rüstungswende or 'armaments turning point', when he switched expenditure from the navy to the army. This decision was not driven by a reduction in political tensions but by German concern over Russia's quick recovery from its defeat in the Russo-Japanese War and subsequent 1905 Russian Revolution . Economic reforms led to a significant post-1908 expansion of railways and transportation infrastructure, particularly in its western border regions. Since Germany and Austria-Hungary relied on faster mobilisation to compensate for their numerical inferiority compared to Russia,

In 1973 , Saudi Arabia and other Arab nations imposed an oil embargo against the United States, United Kingdom, Japan and other Western nations which supported Israel in the Yom Kippur War of October 1973. The embargo caused an oil crisis . This was followed by the 1979 oil crisis , which was caused by a drop in oil production in the wake of the Iranian Revolution and caused oil prices to more than double. The two oil price shocks had many short- and long-term effects on global politics and

Even before the first feasibility studies began, the oil companies had chosen the approximate route of the pipeline. Because TAPS hoped to begin laying pipe by September 1969, substantial orders were placed for steel pipeline 48 inches (122 cm) in diameter. No American company manufactured pipe of that specification, so three Japanese companies— Sumitomo Metal Industries , Nippon Steel Corporation and Nippon Kokan Kabushiki Kaisha—received

As a result, Austria had to keep sizeable forces on the Serbian front, weakening their efforts against Russia. Serbia's victory against Austria-Hungary in the 1914 invasion has been called one of the major upset victories of the twentieth century. In 1915,
14544-758: The Austrians briefly occupied the Serbian capital, Belgrade . A Serbian counter-attack in the Battle of Kolubara succeeded in driving them from the country by the end of 1914. For the first 10 months of 1915, Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats scored a coup by persuading Bulgaria to join the attack on Serbia. The Austro-Hungarian provinces of Slovenia , Croatia and Bosnia provided troops for Austria-Hungary. Montenegro allied itself with Serbia. Bulgaria declared war on Serbia on 14 October 1915 and joined in
14746-553: The Balkan Wars, such as Serbia and Greece, felt cheated of their "rightful gains", while for Austria it demonstrated the apparent indifference with which other powers viewed their concerns, including Germany. This complex mix of resentment, nationalism and insecurity helps explain why the pre-1914 Balkans became known as the " powder keg of Europe ". On 28 June 1914, Archduke Franz Ferdinand of Austria , heir presumptive to Emperor Franz Joseph I of Austria , visited Sarajevo ,
14948-404: The Central Powers. However, the pro-German King Constantine I dismissed the pro-Allied government of Eleftherios Venizelos before the Allied expeditionary force arrived. The Macedonian front was at first mostly static. French and Serbian forces retook limited areas of Macedonia by recapturing Bitola on 19 November 1916 following the costly Monastir offensive , which brought stabilisation of
15150-649: The Chinese Shandong peninsula at Tsingtao . After Vienna refused to withdraw its cruiser SMS Kaiserin Elisabeth from Tsingtao, Japan declared war on Austria-Hungary, and the ship was sunk in November 1914. Within a few months, Allied forces had seized all German territories in the Pacific, leaving only isolated commerce raiders and a few holdouts in New Guinea. Some of the first clashes of
15352-489: The Conservation Foundation, warned: "The oil might last for fifty years. A road would remain forever." This argument relied upon the slow growth of plants and animals in far northern Alaska due to the harsh conditions and short growing season. In testimony, an environmentalist argued that arctic trees, though only a few feet tall, had been seedlings "when George Washington was inaugurated". The portion of
15554-455: The Earth's surface. Unusual magma intrusions, however, could have created greater localized heating. Geologists often refer to the temperature range in which oil forms as an "oil window" . Below the minimum temperature oil remains trapped in the form of kerogen. Above the maximum temperature the oil is converted to natural gas through the process of thermal cracking . Sometimes, oil formed at extreme depths may migrate and become trapped at
15756-623: The German High Seas Fleet was confined to port. German U-boats attempted to cut the supply lines between North America and Britain. The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. The United States launched a protest, and Germany changed its rules of engagement. After the sinking of the passenger ship RMS Lusitania in 1915, Germany promised not to target passenger liners, while Britain armed its merchant ships, placing them beyond
15958-640: The German Army increased in size from 1908 to 1914, he changed the allocation of forces between the two wings to 70:30. He also considered Dutch neutrality essential for German trade and cancelled the incursion into the Netherlands, which meant any delays in Belgium threatened the viability of the plan. Historian Richard Holmes argues that these changes meant the right wing was not strong enough to achieve decisive success. The initial German advance in
16160-804: The German right wing would sweep through the Netherlands and Belgium , then swing south, encircling Paris and trapping the French army against the Swiss border. The plan's creator, Alfred von Schlieffen , head of the German General Staff from 1891 to 1906, estimated that this would take six weeks, after which the German army would transfer to the East and defeat the Russians. The plan was substantially modified by his successor, Helmuth von Moltke
16362-541: The Germans bled heavily as well, with anywhere from 700,000 to 975,000 casualties between the two combatants. Verdun became a symbol of French determination and self-sacrifice. The Battle of the Somme was an Anglo-French offensive from July to November 1916. The opening day on 1 July 1916 was the bloodiest single day in the history of the British Army , which suffered 57,500 casualties, including 19,200 dead. As
16564-417: The House and Senate committees with oversight of the project, Hickel was given the authority to lift the land freeze and give the go-ahead to TAPS. TAPS began issuing letters of intent to contractors for construction of the "haul road", a highway running the length of the pipeline route to be used for construction. Heavy equipment was prepared, and crews prepared to go to work after Hickel gave permission and
16766-625: The Interior Rogers Morton allowed 45 days of comment after the release, and conservationists created a 1,300-page document opposing the impact statement. This document failed to sway Judge Hart, who lifted the injunction on the project on August 15, 1972. The environmental groups that had filed the injunction appealed the decision, and on October 6, 1972, the U.S. District Court of Appeals in Washington, D.C., partially reversed Hart's decision. The appeals court said that although
16968-688: The Middle East. In all, 140,000 soldiers served on the Western Front and nearly 700,000 in the Middle East, with 47,746 killed and 65,126 wounded. The suffering engendered by the war, as well as the failure of the British government to grant self-government to India afterward, bred disillusionment, resulting in the campaign for full independence led by Mahatma Gandhi . Pre-war military tactics that had emphasised open warfare and individual riflemen proved obsolete when confronted with conditions prevailing in 1914. Technological advances allowed
17170-494: The Minerals Leasing Act did not cover the pipeline's requirements, Alyeska and the oil companies began lobbying Congress to either amend the act or create a new law that would permit a larger right-of-way. The Senate Interior Committee began the first hearings on a series of bills to that effect on March 9, 1973. Environmental opposition switched from contesting the pipeline on NEPA grounds to fighting an amendment to
17372-455: The Native lawsuit to halt work on the Trans-Alaska Pipeline, this precedent was frequently mentioned in debate, causing pressure to resolve the situation more quickly than the 33 years it had taken for the Tlingits to be satisfied. Between 1968 and 1971, a succession of bills were introduced into the U.S. Congress to compensate statewide Native claims. The earliest bill offered $ 7 million, but this
17574-589: The Navy suspended funding for the project. The USGS found several oil fields, most notably the Alpine and Umiat Oil Field , but none were cost-effective to develop. Four years after the Navy suspended its survey, Richfield Oil Corporation (later Atlantic Richfield and ARCO) drilled an enormously successful oil well near the Swanson River in southern Alaska, near Kenai . The resulting Swanson River Oil Field
17776-785: The Ottomans joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France, then to transfer its forces to the east, but its advance was halted in September , and by the end of the year the Western Front consisted of a continuous line of trenches stretching from the English Channel to Switzerland. The Eastern Front was more dynamic, but neither side gained a decisive advantage, despite costly offensives. Italy , Bulgaria , Romania , Greece and others joined in from 1915 onward. In April 1917,
17978-613: The Ottomans' territory in the Balkans during the 1912–1913 First Balkan War , much to the surprise of outside observers. The Serbian capture of ports on the Adriatic resulted in partial Austrian mobilisation, starting on 21 November 1912, including units along the Russian border in Galicia . The Russian government decided not to mobilise in response, unprepared to precipitate a war. The Great Powers sought to re-assert control through
18180-642: The Permanent Fund. That deposit and subsequent ones were invested entirely in bonds, but debates quickly arose about the style of investments and what they should be used for. In 1980, the Alaska Legislature created the Alaska Permanent Fund Corporation to manage the investments of the Permanent Fund, and it passed the Permanent Fund Dividend program, which provided for annual payments to Alaskans from
18382-613: The Russian Stavka agreed with the French to attack Germany within fifteen days of mobilisation, ten days before the Germans had anticipated, although it meant the two Russian armies that entered East Prussia on 17 August did so without many of their support elements. By the end of 1914, German troops held strong defensive positions inside France, controlled the bulk of France's domestic coalfields, and inflicted 230,000 more casualties than it lost itself. However, communications problems and questionable command decisions cost Germany
18584-632: The Sagavanirktok River forced workers to come up with solutions for unforeseen problems. Faulty welds and accusations of poor quality control caused a Congressional investigation that ultimately revealed little. More than $ 8 billion was spent to build the 800 miles (1,300 km) of pipeline, the Valdez Marine Terminal, and 12 pump stations. The construction effort also had a human toll. Thirty-two Alyeska and contract employees died from causes directly related to construction. That figure does not include common carrier casualties. Construction of
18786-529: The Senate. The amendment declared that the pipeline project fulfilled all aspects of NEPA and modified the Mineral Leasing Act to allow the larger right-of-way for the Alaska pipeline. Upon reconsideration , the vote was tied at 49–49 and required the vote of vice president Spiro Agnew , who supported the amendment; a similar amendment was passed in the House on August 2. On October 17, 1973,
18988-538: The Serbian retreat toward the Adriatic coast in the Battle of Mojkovac on 6–7 January 1916, but ultimately the Austrians also conquered Montenegro. The surviving Serbian soldiers were evacuated to Greece. After the conquest, Serbia was divided between Austro-Hungary and Bulgaria. In late 1915, a Franco-British force landed at Salonica in Greece to offer assistance and to pressure its government to declare war against
19190-533: The Soviet Union included the goal to capture the Baku oilfields , as it would provide much-needed oil supplies for the German military which was suffering from blockades. Oil exploration in North America during the early 20th century later led to the U.S. becoming the leading producer by mid-century. As petroleum production in the U.S. peaked during the 1960s, the United States was surpassed by Saudi Arabia and
19392-468: The Trans-Alaska Pipeline. Hearings in both the U.S. Senate and the House continued through the summer of 1973 on both new bills and amendments to the Mineral Leasing Act. On July 13, an amendment calling for more study of the project—the Mondale-Bayh Amendment—was defeated. This was followed by another victory for pipeline proponents when an amendment by Alaska Sen. Mike Gravel was passed by
19594-517: The United States became the world's largest producer. About 80 percent of the world's readily accessible reserves are located in the Middle East , with 62.5 percent coming from the Arab five: Saudi Arabia , United Arab Emirates , Iraq , Qatar , and Kuwait . A large portion of the world's total oil exists as unconventional sources, such as bitumen in Athabasca oil sands and extra heavy oil in
19796-433: The United States. These reserves were areas thought to be rich in oil and set aside for future drilling by the U.S. Navy. Naval Petroleum Reserve No. 4 was sited in Alaska's far north, just south of Barrow, and encompassed 23,000,000 acres (93,078 km). The first explorations of NPR-4 were undertaken by the U.S. Geological Survey from 1923 to 1925 and focused on mapping, identifying and characterizing coal resources in
19998-651: The West was very successful. By the end of August, the Allied left, which included the British Expeditionary Force (BEF), was in full retreat , and the French offensive in Alsace-Lorraine was a disastrous failure, with casualties exceeding 260,000. German planning provided broad strategic instructions while allowing army commanders considerable freedom in carrying them out at the front, but von Kluck used this freedom to disobey orders, opening
20200-485: The Younger . Under Schlieffen, 85% of German forces in the west were assigned to the right wing, with the remainder holding along the frontier. By keeping his left-wing deliberately weak, he hoped to lure the French into an offensive into the "lost provinces" of Alsace-Lorraine , which was the strategy envisaged by their Plan XVII . However, Moltke grew concerned that the French might push too hard on his left flank and as
20402-446: The aggressor, German Chancellor Bethmann Hollweg delayed the commencement of war preparations until 31 July. That afternoon, the Russian government were handed a note requiring them to "cease all war measures against Germany and Austria-Hungary" within 12 hours. A further German demand for neutrality was refused by the French who ordered general mobilization but delayed declaring war. The German General Staff had long assumed they faced
20604-627: The air at a recorded rate of 480 cubic metres (3,000 bbl) per day. By the end of the 19th century the Russian Empire, particularly the Branobel company in Azerbaijan , had taken the lead in production. Access to oil was and still is a major factor in several military conflicts of the 20th century, including World War II , during which oil facilities were a major strategic asset and were extensively bombed . The German invasion of
20806-551: The area around modern Baku , Azerbaijan . These fields were described by the Persian geographer Abu Bakr al-Razi in the 10th century, and by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads. Arab and Persian chemists also distilled crude oil to produce flammable products for military purposes. Through Islamic Spain , distillation became available in Western Europe by
21008-474: The area's remoteness and harsh climate. It was estimated that between 200,000,000 barrels (32,000,000 m) and 500,000,000 barrels (79,000,000 m) of oil would have to be recovered to make a North Slope oil field commercially viable. In 1967, Atlantic Richfield (ARCO) began detailed survey work in the Prudhoe Bay area. By January 1968, reports began circulating that natural gas had been discovered by
21210-474: The attack by the Austro-Hungarian army under Mackensen's army of 250,000 that was already underway. Serbia was conquered in a little more than a month, as the Central Powers, now including Bulgaria, sent in 600,000 troops in total. The Serbian army, fighting on two fronts and facing certain defeat, retreated into northern Albania . The Serbs suffered defeat in the Battle of Kosovo . Montenegro covered
21412-442: The beginning of time. Alaska historian Terrence Cole Since the completion of the Trans-Alaska Pipeline System in 1977, the government of the state of Alaska has been reliant on taxes paid by oil producers and shippers. Prior to 1976, Alaska's personal income tax rate was 14.5 percent—the highest in the United States. The gross state product was $ 8 billion, and Alaskans earned $ 5 billion in personal income. Thirty years after
21614-543: The best way of achieving this. However, the Foreign Ministry had no solid proof of Serbian involvement. On 23 July, Austria delivered an ultimatum to Serbia, listing ten demands made intentionally unacceptable to provide an excuse for starting hostilities. Serbia ordered general mobilization on 25 July, but accepted all the terms, except for those empowering Austrian representatives to suppress "subversive elements" inside Serbia, and take part in
21816-483: The border and pre-empt such a move. To avoid violating Belgian neutrality, he was told any advance could come only after a German invasion. Instead, the French cabinet ordered its Army to withdraw 10 km behind the German frontier, to avoid provoking war. On 2 August, Germany occupied Luxembourg and exchanged fire with French units when German patrols entered French territory; on 3 August, they declared war on France and demanded free passage across Belgium, which
22018-486: The campaign saw the first use of anti-aircraft warfare after an Austrian plane was shot down with ground-to-air fire, as well as the first medical evacuation by the Serbian army. Upon mobilisation, in accordance with the Schlieffen Plan , 80% of the German Army was located on the Western Front, with the remainder acting as a screening force in the East. Rather than a direct attack across their shared frontier,
22220-547: The capacity at that time). However, construction was delayed for nearly 5 years due to legal and environmental issues. The eight oil companies that owned the rights to the oil hired Bechtel for the pipeline design and construction and Fluor for the 12 pump stations and the Valdez Terminal. Preconstruction work during 1973 and 1974 was critical and included the building of camps to house workers, construction of roads and bridges where none existed, and carefully laying out
22422-649: The capital of the recently annexed Bosnia and Herzegovina . Cvjetko Popović , Gavrilo Princip , Nedeljko Čabrinović , Trifko Grabež , Vaso Čubrilović ( Bosnian Serbs ) and Muhamed Mehmedbašić (from the Bosniaks community), from the movement known as Young Bosnia , took up positions along the Archduke's motorcade route, to assassinate him. Supplied with arms by extremists within the Serbian Black Hand intelligence organisation, they hoped his death would free Bosnia from Austrian rule. Čabrinović threw
22624-578: The chance of a decisive outcome, while it had failed to achieve the primary objective of avoiding a long, two-front war. As was apparent to several German leaders, this amounted to a strategic defeat; shortly after the First Battle of the Marne , Crown Prince Wilhelm told an American reporter "We have lost the war. It will go on for a long time but lost it is already." On 30 August 1914, New Zealand occupied German Samoa (now Samoa ). On 11 September,
22826-654: The city of 15,000 people. Trouble was incited sometimes by prostitutes' pimps , who engaged in turf fights . In 1976, police responded to a shootout between warring pimps who wielded automatic firearms . By and large, however, the biggest police issue was the number of drunken brawls and fighting. On the pipeline itself, thievery was a major problem. Poor accounting and record keeping allowed large numbers of tools and large amounts of equipment to be stolen. The Los Angeles Times reported in 1975 that as many as 200 of Alyeska's 1,200 yellow-painted trucks were missing from Alaska and "scattered from Miami to Mexico City". Alyeska denied
23028-474: The coal industry dominated the petroleum technologies. Chemist James Young in 1847 noticed a natural petroleum seepage in the coal mine at riddings Alfreton , Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a more viscous oil suitable for lubricating machinery. In 1848, Young set up a small business refining crude oil. Young eventually succeeded, by distilling cannel coal at low heat, in creating
23230-520: The cost of 199 submarines. World War I also saw the first use of aircraft carriers in combat, with HMS Furious launching Sopwith Camels in a successful raid against the Zeppelin hangars at Tondern in July 1918, as well as blimps for antisubmarine patrol. Faced with Russia in the east, Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses,
23432-522: The creation of new independent states, including Poland , Finland , the Baltic states , Czechoslovakia , and Yugoslavia . The League of Nations was established to maintain world peace, but its failure to manage instability during the interwar period contributed to the outbreak of World War II in 1939. Before World War II , the events of 1914–1918 were generally known as the Great War or simply
23634-449: The creation of strong defensive systems largely impervious to massed infantry advances, such as barbed wire , machine guns and above all far more powerful artillery , which dominated the battlefield and made crossing open ground extremely difficult. Both sides struggled to develop tactics for breaching entrenched positions without heavy casualties. In time, technology enabled the production of new offensive weapons, such as gas warfare and
23836-965: The crowds listened to music and drank wine, as if nothing had happened." Nevertheless, the impact of the murder of the heir to the throne was significant, and has been described by historian Christopher Clark as a "9/11 effect, a terrorist event charged with historic meaning, transforming the political chemistry in Vienna". Austro-Hungarian authorities encouraged subsequent anti-Serb riots in Sarajevo . Violent actions against ethnic Serbs were also organised outside Sarajevo, in other cities in Austro-Hungarian-controlled Bosnia and Herzegovina, Croatia and Slovenia. Austro-Hungarian authorities in Bosnia and Herzegovina imprisoned approximately 5,500 prominent Serbs, 700 to 2,200 of whom died in prison. A further 460 Serbs were sentenced to death. A predominantly Bosniak special militia known as
24038-809: The demand, a Fairbanks high school ran in two shifts: one in the morning and the other in the afternoon in order to teach students who also worked eight hours per day. More wages and more people meant higher demand for goods and services. Waiting in line became a fact of life in Fairbanks, and the Fairbanks McDonald's became No. 2 in the world for sales—behind only the recently opened Stockholm store. Alyeska and its contractors bought in bulk from local stores, causing shortages of everything from cars to tractor parts, water softener salt, batteries and ladders. The large sums of money being made and spent caused an upsurge in crime and illicit activity in towns along
24240-573: The earliest Chinese writings, cites that oil in its raw state, without refining, was first discovered, extracted, and used in China in the first century BCE. In addition, the Chinese were the first to record the use of petroleum as fuel as early as the fourth century BCE. By 347 CE, oil was produced from bamboo-drilled wells in China. In the 7th century, petroleum was among the essential ingredients for Greek fire , an incendiary projectile weapon that
24442-464: The end of March. Criticisms of the project included its effect on the Alaska tundra , possible pollution, harm to animals, geographic features, and the lack of much engineering information from Alyeska. One element of opposition the report quelled was the discussion of alternatives. All the proposed alternatives—extension of the Alaska Railroad, an alternative route through Canada, establishing
24644-469: The environment and human health. Extraction , refining and burning of petroleum fuels all release large quantities of greenhouse gases , so petroleum is one of the major contributors to climate change . Other negative environmental effects include direct releases, such as oil spills , as well as air and water pollution at almost all stages of use. These environmental effects have direct and indirect health consequences for humans. Oil has also been
24846-525: The environmental debate with the biggest symbolic impact took place when discussing the pipeline's impact on caribou herds. Environmentalists proposed that the pipeline would have an effect on caribou similar to the effect of the U.S. transcontinental railroad on the American bison population of North America. Pipeline critics said the pipeline would block traditional migration routes, making caribou populations smaller and making them easier to hunt. This idea
25048-695: The expansion of the French colonial empire . In 1873, Bismarck negotiated the League of the Three Emperors , which included Austria-Hungary , Russia and Germany. After the 1877–1878 Russo-Turkish War , the League was dissolved due to Austrian concerns over the expansion of Russian influence in the Balkans , an area they considered to be of vital strategic interest. Germany and Austria-Hungary then formed
25250-425: The fact that it happened at relatively low temperatures (when compared to commercial pyrolysis plants) of 60 to several hundred °C. Pyrolysis was possible because of the long reaction times involved. Heat for catagenesis came from the decomposition of radioactive materials of the crust, especially K , Th , U and U . The heat varied with geothermal gradient and was typically 10–30 °C per km of depth from
25452-579: The fall of 1969, the Department of the Interior and TAPS set about bypassing the land freeze by obtaining waivers from the various native villages that had claims to a portion of the proposed right of way. By the end of September, all the relevant villages had waived their right-of-way claims, and Secretary of the Interior Wally Hickel asked Congress to lift the land freeze for the entire TAPS project. After several months of questioning by
25654-648: The field, the Boeing RC-1 . General Dynamics proposed a line of tanker submarines for travel beneath the Arctic ice cap , and another group proposed extending the Alaska Railroad to Prudhoe Bay. To test this, in 1969 Humble Oil and Refining Company sent a specially fitted oil tanker, the SS ; Manhattan , to test the feasibility of transporting oil via ice-breaking tankers to market. The Manhattan
25856-477: The first barrel of oil reached Valdez, tens of thousands of people worked on the pipeline. Thousands of workers came to Alaska, attracted by the prospect of high-paying jobs at a time when most of the rest of the United States was undergoing a recession. Construction workers endured long hours, cold temperatures, and brutal conditions. Difficult terrain, particularly in Atigun Pass , Keystone Canyon , and near
26058-400: The first time on the Western Front. Several types of gas soon became widely used by both sides and though it never proved a decisive, battle-winning weapon, it became one of the most feared and best-remembered horrors of the war. In February 1916, the Germans attacked French defensive positions at the Battle of Verdun , lasting until December 1916. Casualties were greater for the French, but
26260-595: The front. Serbian and French troops finally made a breakthrough in September 1918 in the Vardar offensive , after most German and Austro-Hungarian troops had been withdrawn. The Bulgarians were defeated at the Battle of Dobro Pole , and by 25 September British and French troops had crossed the border into Bulgaria proper as the Bulgarian army collapsed. Bulgaria capitulated four days later, on 29 September 1918. The German high command responded by despatching troops to hold
26462-762: The global economy. They led to sustained reductions in demand as a result of substitution to other fuels, especially coal and nuclear, and improvements in energy efficiency , facilitated by government policies. High oil prices also induced investment in oil production by non-OPEC countries, including Prudhoe Bay in Alaska, the North Sea offshore fields of the United Kingdom and Norway, the Cantarell offshore field of Mexico, and oil sands in Canada. About 90 percent of vehicular fuel needs are met by oil. Petroleum also makes up 40 percent of total energy consumption in
26664-542: The globe, some of which were subsequently used to attack Allied merchant shipping . These were systematically hunted down by the Royal Navy, though not before causing considerable damage. One of the most successful was the SMS ; Emden , part of the German East Asia Squadron stationed at Qingdao , which seized or sank 15 merchantmen, a Russian cruiser and a French destroyer. Most of the squadron
26866-408: The heavier end of the range, paraffin wax is an alkane with approximately 25 carbon atoms, while asphalt has 35 and up, although these are usually cracked in modern refineries into more valuable products. The lightest fraction, the so-called petroleum gases are subjected to diverse processing depending on cost. These gases are either flared off , sold as liquefied petroleum gas , or used to power
27068-421: The high ground, while their trenches tended to be better built; those constructed by the French and English were initially considered "temporary", only needed until an offensive would destroy the German defences. Both sides tried to break the stalemate using scientific and technological advances. On 22 April 1915, at the Second Battle of Ypres , the Germans (violating the Hague Convention ) used chlorine gas for
27270-520: The high salaries paid to pipeline workers, who were eager to spend their money. The high salaries caused a corresponding demand for higher wages among non-pipeline workers in Alaska. Non-pipeline businesses often could not keep up with the demand for higher wages, and job turnover was high. Yellow cab in Fairbanks had a turnover rate of 800 percent; a nearby restaurant had a turnover rate of more than 1,000 percent. Many positions were filled by high school students promoted above their experience level. To meet
27472-416: The impact statement followed the guidelines set by the National Environmental Policy Act, it did not follow the Minerals Leasing Act , which allowed for a smaller pipeline right of way than was required for the Trans-Alaska Pipeline. The oil companies and Alyeska appealed this decision to the U.S. Supreme Court, but in April 1973, the court declined to hear the case. With the appeals court having decided that
27674-429: The interest earned by the fund. After two years of legal arguments about who should be eligible for payments, the first checks were distributed to Alaskans. After peaking at more than $ 40 billion in 2007, the fund's value declined to approximately $ 26 billion as of summer 2009. In addition to the Permanent Fund, the state also maintains the Constitutional Budget Reserve , a separate savings account established in 1990 after
27876-435: The invention of the modern kerosene lamp (1853), the introduction of the first modern street lamp in Europe (1853), and the construction of the world's first modern oil "mine" (1854). at Bóbrka , near Krosno (still operational as of 2020). The demand for petroleum as a fuel for lighting in North America and around the world quickly grew. The first oil well in the Americas was drilled in 1859 by Edwin Drake at what
28078-422: The investigation and trial of Serbians linked to the assassination. Claiming this amounted to rejection, Austria broke off diplomatic relations and ordered partial mobilisation the next day; on 28 July, they declared war on Serbia and began shelling Belgrade . Russia ordered general mobilization in support of Serbia on 30 July. Anxious to ensure backing from the SPD political opposition by presenting Russia as
28280-446: The large number of co-eluted hydrocarbons within oil, many cannot be resolved by traditional gas chromatography. This unresolved complex mixture (UCM) of hydrocarbons is particularly apparent when analysing weathered oils and extracts from tissues of organisms exposed to oil. Crude oil varies greatly in appearance depending on its composition. It is usually black or dark brown (although it may be yellowish, reddish, or even greenish). In
28482-417: The largest in North America and the 18th largest in the world. The problem soon became how to develop the oil field and ship product to U.S. markets. Pipeline systems represent a high initial cost but lower operating costs, but no pipeline of the necessary length had yet been constructed. Several other solutions were offered. Boeing proposed a series of gigantic 12-engine tanker aircraft to transport oil from
28684-491: The leasing act or a new bill. By the spring and summer of 1973, these opposition groups attempted to persuade Congress to endorse a Trans-Canada oil pipeline or a railroad. They believed the "leave it in the ground" argument was doomed to fail, and the best way to oppose the pipeline would be to propose an ineffective alternative which could be easily defeated. The problem with this approach was that any such alternative would cover more ground and be more damaging environmentally than
28886-434: The legal injunction against pipeline construction. In October 1971, President Richard Nixon signed the Alaska Native Claims Settlement Act (ANCSA). Under the act, Native groups would renounce their land claims in exchange for $ 962.5 million and 148.5 million acres (601,000 km) in federal land. The money and land were split up among village and regional corporations, which then distributed shares of stock to Natives in
29088-411: The lower regions. As a consequence, compounds of this mixture began to combine in poorly understood ways to kerogen . Combination happened in a similar fashion as phenol and formaldehyde molecules react to urea-formaldehyde resins, but kerogen formation occurred in a more complex manner due to a bigger variety of reactants. The total process of kerogen formation from the beginning of anaerobic decay
29290-899: The matter to H 2 S and N 2 respectively by using the matter as a source for other reactants. Due to such anaerobic bacteria, at first, this matter began to break apart mostly via hydrolysis : polysaccharides and proteins were hydrolyzed to simple sugars and amino acids respectively. These were further anaerobically oxidized at an accelerated rate by the enzymes of the bacteria: e.g., amino acids went through oxidative deamination to imino acids , which in turn reacted further to ammonia and α-keto acids . Monosaccharides in turn ultimately decayed to CO 2 and methane . The anaerobic decay products of amino acids, monosaccharides, phenols and aldehydes combined into fulvic acids . Fats and waxes were not extensively hydrolyzed under these mild conditions. Some phenolic compounds produced from previous reactions worked as bactericides and
29492-401: The maximum tax rate on profits is 50 percent. The rate fluctuates based on the cost of oil, with lower prices incurring lower tax rates. The state also claims 12.5 percent of all oil produced in the state. This "royalty oil" is not taxed but is sold back to the oil companies, generating additional revenue. At a local level, the pipeline owners pay property taxes on the portions of the pipeline and
29694-409: The ocean, even to neutral ships. Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare. The Battle of Jutland in May/June 1916 was the only full-scale clash of battleships during the war, and one of the largest in history. The clash was indecisive, though the Germans inflicted more damage than they received; thereafter the bulk of
29896-444: The other fields on the North Slope since 1977 is worth more than all the fish ever caught, all the furs ever trapped, all the trees chopped down; throw in all the copper, whalebone, natural gas, tin, silver, platinum, and anything else ever extracted from Alaska too. The balance sheet of Alaskan history is simple: One Prudhoe Bay is worth more in real dollars than everything that has been dug out, cut down, caught or killed in Alaska since
30098-452: The overall form remains mostly the same. Alaska receives royalties from oil production on state land. The state also has a property tax on oil production structures and transportation (pipeline) property—the only state property tax in Alaska. There is a special corporate income tax on petroleum companies, and the state taxes the amount of petroleum produced. This production tax is levied on the cost of oil at Pump Station 1. To calculate this tax,
30300-411: The pipeline began operating, the state had no personal income tax, the gross state product was $ 39 billion, and Alaskans earned $ 25 billion in personal income. Alaska moved from the most heavily taxed state to the most tax-free state. The difference was the Trans-Alaska Pipeline System and the taxes and revenue it brought to Alaska. Alyeska and the oil companies injected billions of dollars into
30502-414: The pipeline caused a massive economic boom in towns up and down the pipeline route. Prior to construction, most residents in towns like Fairbanks—still recovering from the devastating 1967 Fairbanks Flood —strongly supported the pipeline. By 1976, after the town's residents had endured a spike in crime, overstressed public infrastructure, and an influx of people unfamiliar with Alaska customs, 56 percent said
30704-411: The pipeline facilities that lay within districts that impose a property tax. This property tax is based on the pipeline's value (as assessed by the state) and the local property tax rate. In the Fairbanks North Star Borough , for example, pipeline owners paid $ 9.2 million in property taxes—approximately 10 percent of all property taxes paid in the borough. The enormous amount of public revenue created by
30906-528: The pipeline had changed Fairbanks for the worse. The boom was even greater in Valdez, where the population jumped from 1,350 in 1974 to 6,512 by the summer of 1975 and 8,253 in 1976. This increase in population caused many adverse effects. Home prices skyrocketed—a home that sold for $ 40,000 in 1974 was purchased for $ 80,000 in 1975. In Valdez, lots of land that sold for $ 400 in the late 1960s went for $ 4,000 in 1973, $ 8,000 in 1974, and $ 10,000 in 1975. Home and apartment rentals were correspondingly squeezed upward by
31108-450: The pipeline project before 1970, the introduction of the National Environmental Policy Act allowed them legal grounds to halt the project. Arctic engineers had raised concerns about the way plans for a subterranean pipeline showed ignorance of Arctic engineering and permafrost in particular. A clause in NEPA requiring a study of alternatives and another clause requiring an environmental impact statement turned those concerns into tools used by
31310-425: The pipeline provoked debates about what to do with the windfall. The record $ 900 million created by the Prudhoe Bay oil lease sale took place at a time when the entire state budget was less than $ 118 million, yet the entire amount created by the sale was used up by 1975. Taxes on the pipeline and oil carried by it promised to bring even more money into state coffers. To ensure that oil revenue wasn't spent as it came in,
31512-433: The pipeline right of way to avoid difficult river crossings and animal habitats. Construction of the pipeline system took place between 1975 and 1977. It was important for the United States to have a domestic source of oil to offset the high rise in foreign oil and the Alaska Pipeline fulfilled that obligation. Building oil pipelines in the 1950s and 60s was not difficult in the contiguous United States . However, in building
31714-431: The pipeline route. This was exacerbated by the fact that police officers and state troopers resigned in large groups to become pipeline security guards at wages far in excess of those available in public-sector jobs. Fairbanks' Second Avenue became a notorious hangout for prostitutes , and dozens of bars operated throughout town. In 1975, the Fairbanks Police Department estimated between 40 and 175 prostitutes were working in
31916-416: The pipeline would scare away the whales and caribou that are relied upon for food. In both the courts and Congress, Alyeska and the oil companies fought for the pipeline's construction amidst opposition concerning the pipeline's EIS (environmental impact statement). The arguments continued through 1971. Objections about the caribou herds were countered by observations of Davidson Ditch , a water pipeline with
32118-400: The plan. All the arguments both for and against the pipeline were incorporated into the 3,500-page, 9-volume final environmental impact statement, which was released on March 20, 1972. Although Alaska Sen. Ted Stevens felt the statement "was not written by a proponent," it maintained the general approval for pipeline construction that was demonstrated in the draft statement. U.S. Secretary of
32320-410: The problem and said only 20–30 trucks were missing. The theft problem was typified by pipeliners' practice of mailing empty boxes to pipeline camps. The boxes then would be filled with items and shipped out. After Alyeska ruled that all packages had to be sealed in the presence of a security guard, the number of packages being sent from camps dropped by 75 percent. The wealth generated by Prudhoe Bay and
32522-556: The proportion of chemical elements varies over fairly narrow limits as follows: Four different types of hydrocarbon appear in crude oil. The relative percentage of each varies from oil to oil, determining the properties of each oil. The alkanes from pentane (C 5 H 12 ) to octane (C 8 H 18 ) are refined into gasoline, the ones from nonane (C 9 H 20 ) to hexadecane (C 16 H 34 ) into diesel fuel , kerosene and jet fuel . Alkanes with more than 16 carbon atoms can be refined into fuel oil and lubricating oil . At
32724-430: The proposed route and plan. Max Brewer , an arctic expert in charge of the Naval Arctic Research Laboratory at Barrow, concluded that the plan to bury most of the pipeline was completely unfeasible because of the abundance of permafrost along the route. In a report, Brewer said the hot oil conveyed by the pipeline would melt the underlying permafrost, causing the pipeline to fail as its support turned to mud. This report
32926-681: The protection of the " cruiser rules ", which demanded warning and movement of crews to "a place of safety" (a standard that lifeboats did not meet). Finally, in early 1917, Germany adopted a policy of unrestricted submarine warfare , realising the Americans would eventually enter the war. Germany sought to strangle Allied sea lanes before the United States could transport a large army overseas, but, after initial successes, eventually failed to do so. The U-boat threat lessened in 1917, when merchant ships began travelling in convoys , escorted by destroyers . This tactic made it difficult for U-boats to find targets, which significantly lessened losses; after
33128-644: The refinery's own burners. During the winter, butane (C 4 H 10 ), is blended into the gasoline pool at high rates, because its high vapour pressure assists with cold starts. The aromatic hydrocarbons are unsaturated hydrocarbons that have one or more benzene rings . They tend to burn with a sooty flame, and many have a sweet aroma. Some are carcinogenic . These different components are separated by fractional distillation at an oil refinery to produce gasoline, jet fuel, kerosene, and other hydrocarbon fractions. The components in an oil sample can be determined by gas chromatography and mass spectrometry . Due to
33330-423: The region or village. The shares paid dividends based on both the settlement and corporation profits. To pipeline developers, the most important aspect of ANCSA was the clause dictating that no Native allotments could be selected in the path of the pipeline. Another objection of the natives was the potential for the pipeline to disrupt a traditional way of life. Many natives were worried that the disruption caused by
33532-412: The reservoir it is usually found in association with natural gas, which being lighter forms a "gas cap" over the petroleum, and saline water which, being heavier than most forms of crude oil, generally sinks beneath it. Crude oil may also be found in a semi-solid form mixed with sand and water, as in the Athabasca oil sands in Canada, where it is usually referred to as crude bitumen . In Canada, bitumen
33734-542: The rising prices and the demand from pipeline workers. Two-room log cabins with no plumbing rented for $ 500 per month. One two-bedroom home in Fairbanks housed 45 pipeline workers who shared beds on a rotating schedule for $ 40 per week. In Valdez, an apartment that rented for $ 286 per month in December 1974 cost $ 520 per month in March 1975 and $ 1,600 per month—plus two mandatory roommates—in April 1975. Hotel rooms were sold out as far away as Glenallen, 115 miles (185 km) north of Valdez. The skyrocketing prices were driven by
33936-684: The same diameter of the Trans-Alaska Pipeline, which caribou were able to jump over. To those who argued that the pipeline would irrevocably alter Alaska wilderness, proponents pointed to the overgrown remnants of the Fairbanks Gold Rush , most of which had been erased 70 years later. Some pipeline opponents were satisfied by Alyeska's preliminary design, which incorporated underground and raised crossings for caribou and other big game, gravel and styrofoam insulation to prevent permafrost melting, automatic leak detection and shutoff, and other techniques. Other opponents, including fishermen who feared tanker leaks south of Valdez, maintained their disagreement with
34138-410: The same time the world's first, small, oil refinery was opened at Jasło in Poland (then Austria), with a larger one opened at Ploiești in Romania shortly after. Romania (then being a vassal of the Ottoman empire) is the first country in the world to have had its annual crude oil output officially recorded in international statistics: 275 tonnes for 1857. In 1858, Georg Christian Konrad Hunäus found
34340-466: The second half of the 19th century, the term became commonly known for the liquid form of hydrocarbons. Petroleum, in one form or another, has been used since ancient times. More than 4300 years ago, bitumen was mentioned when the Sumerians used it to make boats. A tablet of the legend of the birth of Sargon of Akkad mentions a basket which was closed by straw and bitumen. More than 4000 years ago, according to Herodotus and Diodorus Siculus , asphalt
34542-425: The seepages in 1836. Similar seepages were found at the Canning River in 1919 by Ernest de Koven Leffingwell . Following the First World War , as the United States Navy converted its ships from coal to fuel oil , a stable supply of oil became important to the U.S. government. Accordingly, President Warren G. Harding established by executive order a series of Naval Petroleum Reserves (NPR-1 through -4) across
34744-448: The snow melted. Before Hickel could act, however, several Alaska Native and conservation groups asked a judge in Washington, D.C., to issue an injunction against the project. Several of the native villages that had waived claims on the right of way reneged because TAPS had not chosen any Native contractors for the project and the contractors chosen were not likely to hire Native workers. On April 1, 1970, Judge George Luzerne Hart, Jr. , of
34946-411: The state takes the market value of the oil, subtracts transportation costs (tanker and pipeline tariffs), subtracts production costs, then multiplies the resulting amount per barrel of oil produced each month. The state then takes a percentage of the dollar figure produced. Under the latest taxation system, introduced by former governor Sarah Palin in 2007 and passed by the Alaska Legislature that year,
35148-440: The substance the Iñupiat called pitch and recognized it as petroleum. Charles Brower, a whaler who settled at Barrow and operated trading posts along the Arctic coast, directed geologist Alfred Hulse Brooks to oil seepages at Cape Simpson and Fish Creek in the far north of Alaska, east of the village of Barrow . Brooks' report confirmed the observations of Thomas Simpson, an officer of the Hudson's Bay Company who first observed
35350-415: The term First World War was in September 1914 by German biologist and philosopher Ernst Haeckel who stated, "There is no doubt that the course and character of the feared 'European War' ... will become the first world war in the full sense of the word." For much of the 19th century, the major European powers maintained a tenuous balance of power , known as the Concert of Europe . After 1848, this
35552-408: The term stems from monasteries in southern Italy where it was in use by the end of the first millennium as an alternative for the older term " naphtha ". After that, the term was used in numerous manuscripts and books, such as in the treatise De Natura Fossilium , published in 1546 by the German mineralogist Georg Bauer , also known as Georgius Agricola. After the advent of the oil industry, during
35754-584: The threat posed by the closing of this gap was more important than competing with the Royal Navy. After Germany expanded its standing army by 170,000 troops in 1913, France extended compulsory military service from two to three years; similar measures were taken by the Balkan powers and Italy, which led to increased expenditure by the Ottomans and Austria-Hungary. Absolute figures are difficult to calculate due to differences in categorising expenditure since they often omit civilian infrastructure projects like railways which had logistical importance and military use. It
35956-424: The title of E.W. Binney & Co. at Bathgate in West Lothian and E. Meldrum & Co. at Glasgow; their works at Bathgate were completed in 1851 and became the first truly commercial oil-works in the world with the first modern oil refinery. The world's first oil refinery was built in 1856 by Ignacy Łukasiewicz in Austria. His achievements also included the discovery of how to distill kerosene from seep oil,
36158-468: The volume of the world's reserves of conventional oil. Petroleum is a fossil fuel derived from fossilized organic materials , such as zooplankton and algae . Vast amounts of these remains settled to sea or lake bottoms where they were covered in stagnant water (water with no dissolved oxygen ) or sediments such as mud and silt faster than they could decompose aerobically . Approximately 1 m below this sediment, water oxygen concentration
36360-429: The war ended with the Armistice of 11 November 1918 . The Paris Peace Conference of 1919–1920 imposed settlements on the defeated powers, most notably the Treaty of Versailles , by which Germany lost significant territories, was disarmed, and was required to pay large war reparations to the Allies. The dissolution of the Russian, German, Austro-Hungarian, and Ottoman Empires redrew national boundaries and resulted in
36562-413: The war involved British, French, and German colonial forces in Africa. On 6–7 August, French and British troops invaded the German protectorates of Togoland and Kamerun . On 10 August, German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the rest of the war. The German colonial forces in German East Africa , led by Colonel Paul von Lettow-Vorbeck , fought
36764-418: The west , which despite initial successes left the German Army exhausted and demoralised. A successful Allied counter-offensive from August 1918 caused a collapse of the German front line. By early November, Bulgaria, the Ottoman Empire and Austria-Hungary had each signed armistices with the Allies, leaving Germany isolated. Facing a revolution at home , Kaiser Wilhelm II abdicated on 9 November, and
36966-536: The western portion of the reserve and petroleum exploration in the eastern and northern portions of the reserve. These surveys were primarily pedestrian in nature; no drilling or remote sensing techniques were available at the time. These surveys named many of the geographic features of the areas explored, including the Philip Smith Mountains and quadrangle. The petroleum reserve lay dormant until World War II provided an impetus to explore new oil prospects. The first renewed efforts to identify strategic oil assets were
37168-409: The year. Hart issued an injunction against the project, preventing the Interior Department from issuing a construction permit and halting the project in its tracks. After the Department of the Interior was stopped from issuing a construction permit, the unincorporated TAPS consortium was reorganized into the new incorporated Alyeska Pipeline Service Company . Former Humble Oil manager Edward L. Patton
37370-414: Was Alaska's first major commercially producing oil field, and it spurred the exploration and development of many others. By 1965, five oil and 11 natural gas fields had been developed. This success and the previous Navy exploration of its petroleum reserve led petroleum engineers to the conclusion that the area of Alaska north of the Brooks Range surely held large amounts of oil and gas. The problems came from
37572-432: Was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of the Ottoman Empire , which disturbed the long-standing balance of power in Europe, as well as economic competition between nations triggered by industrialisation and imperialism . Growing tensions between the great powers and in the Balkans reached a breaking point on 28 June 1914, when
37774-403: Was activity in various parts of the world in the mid-19th century. A group directed by Major Alexeyev of the Bakinskii Corps of Mining Engineers hand-drilled a well in the Baku region of Bibi-Heybat in 1846. There were engine-drilled wells in West Virginia in the same year as Drake's well. An early commercial well was hand dug in Poland in 1853, and another in nearby Romania in 1857. At around
37976-403: Was challenged by Britain's withdrawal into so-called splendid isolation , the decline of the Ottoman Empire , New Imperialism , and the rise of Prussia under Otto von Bismarck . Victory in the 1870–1871 Franco-Prussian War allowed Bismarck to consolidate a German Empire . Post-1871, the primary aim of French policy was to avenge this defeat, but by the early 1890s, this had switched to
38178-414: Was closed off from external reactants, the resulting composition of the fuel mixture was dependent on the composition of the kerogen via reaction stoichiometry . Three types of kerogen exist: type I (algal), II (liptinic) and III (humic), which were formed mainly from algae , plankton and woody plants (this term includes trees , shrubs and lianas ) respectively. Catagenesis was pyrolytic despite
38380-508: Was escorted back through the Northwest Passage by a Canadian Coast Guard icebreaker, the CCGS John A. Macdonald . Although the Manhattan transited the Northwest Passage again in the summer of 1970, the concept was considered too risky. In February 1969, before the SS Manhattan had even sailed from its East Coast starting point, the Trans-Alaska Pipeline System (TAPS), an unincorporated joint group created by ARCO, British Petroleum , and Humble Oil in October 1968, asked for permission from
38582-407: Was exploited in anti-pipeline advertising, most notably when a picture of a forklift carrying several legally shot caribou was emblazoned with the slogan, "There is more than one way to get caribou across the Alaska Pipeline". The use of caribou as an example of the pipeline's environmental effects reached a peak in the spring of 1971, when the draft environmental statement was being debated. In 1902,
38784-418: Was fitted with an ice-breaking bow, powerful engines, and hardened propellers before successfully traveling the Northwest Passage from the Atlantic Ocean to the Beaufort Sea. During the voyage, the ship suffered damage to several of its cargo holds, which flooded with seawater. Wind-blown ice forced the Manhattan to change its intended route from the M'Clure Strait to the smaller Prince of Wales Strait . It
38986-411: Was flatly rejected. The Alaska Federation of Natives , which had been created in 1966, hired former United States Supreme Court justice Arthur Goldberg , who suggested that a settlement should include 40 million acres (160,000 km) of land and a payment of $ 500 million. The issue remained at a standstill until Alyeska began lobbying in favor of a Native claims act in Congress in order to lift
39188-442: Was for a 100-foot (30.5 m) wide right of way to build a subterranean 48-inch (122-centimeter) pipeline including 11 pumping stations. Another right of way was requested to build a construction and maintenance highway paralleling the pipeline. A document of just 20 pages contained all of the information TAPS had collected about the route up to that stage in its surveying. The Interior Department responded by sending personnel to analyze
39390-423: Was low, below 0.1 mg/L, and anoxic conditions existed. Temperatures also remained constant. As further layers settled into the sea or lake bed, intense heat and pressure built up in the lower regions. This process caused the organic matter to change, first into a waxy material known as kerogen , found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons via
39592-485: Was passed along to the appropriate committees of the U.S. House and Senate , which had to approve the right-of-way proposal because it asked for more land than authorized in the Mineral Leasing Act of 1920 and because it would break a development freeze imposed in 1966 by former Secretary of the Interior Stewart Udall . Udall imposed the freeze on any projects involving land claimed by Alaska Natives in hopes that an overarching Native claims settlement would result. In
39794-645: Was put in charge of the new company and began to lobby strongly in favor of an Alaska Native claims settlement to resolve the disputes over the pipeline right of way. Opposition to construction of the pipeline primarily came from two sources: Alaska Native groups and conservationists . Alaska Natives were upset that the pipeline would cross the land traditionally claimed by a variety of native groups, but no economic benefits would accrue to them directly. Conservationists were angry at what they saw as an incursion into America's last wilderness. Although conservation groups and environmental organizations had voiced opposition to
39996-654: Was refused. Early on the morning of 4 August, the Germans invaded, and Albert I of Belgium called for assistance under the Treaty of London . Britain sent Germany an ultimatum demanding they withdraw from Belgium; when this expired at midnight, without a response, the two empires were at war. Germany promised to support Austria-Hungary's invasion of Serbia, but interpretations of what this meant differed. Previously tested deployment plans had been replaced early in 1914, but those had never been tested in exercises. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia. Beginning on 12 August,
40198-600: Was returning to Germany when it sank two British armoured cruisers at the Battle of Coronel in November 1914, before being virtually destroyed at the Battle of the Falkland Islands in December. The SMS Dresden escaped with a few auxiliaries, but after the Battle of Más a Tierra , these too were either destroyed or interned. Soon after the outbreak of hostilities, Britain began a naval blockade of Germany . This proved effective in cutting off vital supplies, though it violated accepted international law. Britain also mined international waters which closed off entire sections of
40400-586: Was the foundation of German foreign policy but in 1890, he was forced to retire by Wilhelm II . The latter was persuaded not to renew the Reinsurance Treaty by his new Chancellor , Leo von Caprivi . This gave France an opening to agree the Franco-Russian Alliance in 1894, which was then followed by the 1904 Entente Cordiale with Britain. The Triple Entente was completed by the 1907 Anglo-Russian Convention . While not formal alliances, by settling long-standing colonial disputes in Asia and Africa, British support for France or Russia in any future conflict became
40602-426: Was used by Byzantine Greeks against Arab ships, which were then attacking Constantinople . Crude oil was also distilled by Persian chemists , with clear descriptions given in Arabic handbooks such as those of Abu Bakr al-Razi (Rhazes). The streets of Baghdad were paved with tar , derived from petroleum that became accessible from natural fields in the region. In the 9th century, oil fields were exploited in
40804-488: Was used in the construction of the walls and towers of Babylon ; there were oil pits near Ardericca and Babylon, and a pitch spring on Zakynthos . Great quantities of it were found on the banks of the river Issus , one of the tributaries of the Euphrates . Ancient Persian tablets indicate the medicinal and lighting uses of petroleum in the upper levels of their society. The use of petroleum in ancient China dates back to more than 2000 years ago. The I Ching , one of
