91-685: The Turkmenistan–Afghanistan–Pakistan–India (TAPI) Gas Pipeline , also known as Trans-Afghanistan Pipeline , is a natural gas pipeline being developed by the Galkynysh – TAPI Pipeline Company Limited with participation of the Asian Development Bank . The pipeline will transport natural gas from the Galkynysh Gas Field in Turkmenistan through Afghanistan into Pakistan and then to India . A ceremony to mark

182-436: A couple living together (opposite-sex or same-sex). De facto unions are defined in the federal Family Law Act 1975 . De facto relationships provide couples who are living together on a genuine domestic basis with many of the same rights and benefits as married couples. Two people can become a de facto couple by entering into a registered relationship (i.e.: civil union or domestic partnership) or by being assessed as such by

273-410: A court order awards custody, either sole or joint. A de facto monopoly is a system where many suppliers of a product are allowed but the market is so completely dominated by one that the other players are unable to compete or even survive. The related terms oligopoly and monopsony are similar in meaning and this is the type of situation that antitrust laws are intended to eliminate. In finance,

364-427: A de facto national language but no official, de jure national language. Some countries have a de facto national language in addition to an official language. In Lebanon and Morocco , Arabic is an official language (in addition to Tamazight in the case of Morocco), but an additional de facto language is also French. In New Zealand, the official languages are Māori and New Zealand Sign Language ; however, English

455-481: A density 0.5539 times that of air (0.678 kg per standard cubic meter). In the early 1800s, natural gas became known as "natural" to distinguish it from the dominant gas fuel at the time, coal gas . Unlike coal gas, which is manufactured by heating coal, natural gas can be extracted from the ground in its native gaseous form. When the use of natural gas overtook the use of coal gas in English speaking countries in

546-484: A major source of natural gas in the United States and Canada. Because of increased shale gas production the United States was in 2014 the number one natural gas producer in the world. The production of shale gas in the United States has been described as a "shale gas revolution" and as "one of the landmark events in the 21st century." Following the increased production in the United States, shale gas exploration

637-430: A power above the forms of law, claim to act and do really act in their stead. In politics, a de facto leader of a country or region is one who has assumed authority, regardless of whether by lawful, constitutional, or legitimate means; very frequently, the term is reserved for those whose power is thought by some faction to be held by unlawful, unconstitutional, or otherwise illegitimate means, often because it had deposed

728-477: A previous leader or undermined the rule of a current one. De facto leaders sometimes do not hold a constitutional office and may exercise power informally. Not all dictators are de facto rulers. For example, Augusto Pinochet of Chile initially came to power as the chairperson of a military junta , which briefly made him de facto leader of Chile, but he later amended the nation's constitution and made himself president until new elections were called, making him

819-672: A state in Australia. This is because the power to legislate on de facto matters relies on referrals by States to the Commonwealth in accordance with Section 51(xxxvii) of the Australian Constitution , where it states the new federal law can only be applied back within a state. There must be a nexus between the de facto relationship itself and the Australian state. If an Australian de facto couple moves out of

910-604: A state, they do not take the state with them and the new federal law is tied to the territorial limits of a state. The legal status and rights and obligations of the de facto or unmarried couple would then be recognised by the laws of the country where they are ordinarily resident. This is unlike marriage and "matrimonial causes" which are recognised by sections 51(xxi) and (xxii) of the Constitution of Australia and internationally by marriage law and conventions, Hague Convention on Marriages (1978). A de facto relationship

1001-457: A subsequent legitimate government. That doctrine was nullified by the constitutional reform of 1994 . Article 36 states: Two examples of de facto leaders are Deng Xiaoping of the People's Republic of China and general Manuel Noriega of Panama . Both of these men exercised nearly all control over their respective nations for many years despite not having either legal constitutional office or

1092-542: A synthetic crude that can be further refined into finished products, while MTG can produce synthetic gasoline from natural gas. STG+ can produce drop-in gasoline, diesel, jet fuel and aromatic chemicals directly from natural gas via a single-loop process. In 2011, Royal Dutch Shell's 140,000 barrels (22,000 m ) per day F–T plant went into operation in Qatar . Natural gas can be "associated" (found in oil fields ), or "non-associated" (isolated in natural gas fields ), and

1183-493: Is a flammable gaseous fuel made by the destructive distillation of coal . It contains a variety of calorific gases including hydrogen , carbon monoxide , methane , and other volatile hydrocarbons , together with small quantities of non-calorific gases such as carbon dioxide and nitrogen , and was used in a similar way to natural gas. This is a historical technology and is not usually economically competitive with other sources of fuel gas today. Most town "gashouses" located in

1274-458: Is a schematic block flow diagram of a typical natural gas processing plant. It shows the various unit processes used to convert raw natural gas into sales gas pipelined to the end user markets. The block flow diagram also shows how processing of the raw natural gas yields byproduct sulfur, byproduct ethane, and natural gas liquids (NGL) propane, butanes and natural gasoline (denoted as pentanes +). As of mid-2020, natural gas production in

1365-465: Is a third de facto language. Russian was the de facto official language of the central government and, to a large extent, republican governments of the former Soviet Union , but was not declared de jure state language until 1990. A short-lived law, effected April 24, 1990, installed Russian as the sole de jure official language of the Union prior to its dissolution in 1991. In Hong Kong and Macau ,

1456-399: Is also found in coal beds (as coalbed methane ). It sometimes contains a significant amount of ethane , propane , butane , and pentane —heavier hydrocarbons removed for commercial use prior to the methane being sold as a consumer fuel or chemical plant feedstock. Non-hydrocarbons such as carbon dioxide , nitrogen , helium (rarely), and hydrogen sulfide must also be removed before

1547-628: Is beginning in countries such as Poland, China, and South Africa. Chinese geologists have identified the Sichuan Basin as a promising target for shale gas drilling, because of the similarity of shales to those that have proven productive in the United States. Production from the Wei-201 well is between 10,000 and 20,000 m per day. In late 2020, China National Petroleum Corporation claimed daily production of 20 million cubic meters of gas from its Changning-Weiyuan demonstration zone. Town gas

1638-556: Is colorless and odorless, and the second largest greenhouse gas contributor to global climate change after carbon dioxide. Because natural gas is odorless, odorizers such as mercaptan (which smells like rotten eggs ) are commonly added to it for safety so that leaks can be readily detected. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that

1729-438: Is commonly used to refer to what happens in practice, in contrast with de jure ('by law'). In jurisprudence , a de facto law (also known as a de facto regulation ) is a law or regulation that is followed but "is not specifically enumerated by a law." By definition, de facto 'contrasts' de jure which means "as defined by law" or "as a matter of law." For example, if a particular law exists in one jurisdiction, but

1820-416: Is comparable to non-marital relationship contracts (sometimes called "palimony agreements") and certain limited forms of domestic partnership, which are found in many jurisdictions throughout the world. A de facto Relationship is not comparable to common-law marriage , which is a fully legal marriage that has merely been contracted in an irregular way (including by habit and repute). Only nine U.S. states and

1911-537: Is estimated to have 51,000 cubic kilometers (12,000 cu mi) of natural gas and 50 billion barrels (7.9 billion cubic meters) of natural gas condensates . Because natural gas is not a pure product, as the reservoir pressure drops when non-associated gas is extracted from a field under supercritical (pressure/temperature) conditions, the higher molecular weight components may partially condense upon isothermic depressurizing—an effect called retrograde condensation . The liquid thus formed may get trapped as

2002-406: Is followed in another where it has no legal effect (such as in another country), then the law could be considered a de facto regulation (a " de facto regulation" is not an officially prescribed legal classification for a type of law in a particular jurisdiction, rather, it is a concept about law(s). A de facto regulation may be followed by an organization as a result of the market size of

2093-694: Is heated and compressed deep underground. Methanogenic organisms produce methane from a variety of sources, principally carbon dioxide. During petroleum production, natural gas is sometimes flared rather than being collected and used. Before natural gas can be burned as a fuel or used in manufacturing processes, it almost always has to be processed to remove impurities such as water. The byproducts of this processing include ethane , propane , butanes , pentanes , and higher molecular weight hydrocarbons. Hydrogen sulfide (which may be converted into pure sulfur ), carbon dioxide , water vapor , and sometimes helium and nitrogen must also be removed. Natural gas

2184-403: Is natural gas produced from shale . Because shale's matrix permeability is too low to allow gas to flow in economical quantities, shale gas wells depend on fractures to allow the gas to flow. Early shale gas wells depended on natural fractures through which gas flowed; almost all shale gas wells today require fractures artificially created by hydraulic fracturing . Since 2000, shale gas has become

2275-459: Is not a marriage and has significant differences socially, financially and emotionally." The above sense of de facto is related to the relationship between common law traditions and formal (statutory, regulatory, civil) law, and common-law marriages . Common law norms for settling disputes in practical situations, often worked out over many generations to establishing precedent , are a core element informing decision making in legal systems around

2366-406: Is often stored underground [references about geological storage needed]inside depleted gas reservoirs from previous gas wells, salt domes , or in tanks as liquefied natural gas. The gas is injected in a time of low demand and extracted when demand picks up. Storage nearby end users helps to meet volatile demands, but such storage may not always be practicable. With 15 countries accounting for 84% of

2457-452: Is preparing to export natural gas. Floating liquefied natural gas (FLNG) is an innovative technology designed to enable the development of offshore gas resources that would otherwise remain untapped due to environmental or economic factors which currently make them impractical to develop via a land-based LNG operation. FLNG technology also provides a number of environmental and economic advantages: Many gas and oil companies are considering

2548-548: Is primarily dependent on proximity to markets (pipelines), and regulatory restrictions. Natural gas can be indirectly exported through the absorption in other physical output. The expansion of shale gas production in the US has caused prices to drop relative to other countries. This has caused a boom in energy intensive manufacturing sector exports, whereby the average dollar unit of US manufacturing exports has almost tripled its energy content between 1996 and 2012. A "master gas system"

2639-429: Is primarily used in the northern hemisphere. North America and Europe are major consumers. Often well head gases require removal of various hydrocarbon molecules contained within the gas. Some of these gases include heptane , pentane , propane and other hydrocarbons with molecular weights above methane ( CH 4 ). The natural gas transmission lines extend to the natural gas processing plant or unit which removes

2730-743: Is ready to begin work on the TAPI project in Afghanistan with the aim of developing political and economic relations." The roots of this project lie in the involvement of international oil companies in Kazakhstan and Turkmenistan beginning of 1990s. As Russia , who controlled all export pipelines of these countries, consistently refused to allow the use of its pipeline network, these companies needed an independent export route avoiding both Iran and Russia. The original project started on 15 March 1995 when an inaugural memorandum of understanding between

2821-716: Is sometimes informally referred to simply as "gas", especially when it is being compared to other energy sources, such as oil, coal or renewables. However, it is not to be confused with gasoline , which is also shortened in colloquial usage to "gas", especially in North America. Natural gas is measured in standard cubic meters or standard cubic feet . The density compared to air ranges from 0.58 (16.8 g/mole, 0.71 kg per standard cubic meter) to as high as 0.79 (22.9 g/mole, 0.97 kg per scm), but generally less than 0.64 (18.5 g/mole, 0.78 kg per scm). For comparison, pure methane (16.0425 g/mole) has

2912-604: Is traded on a "dry gas" basis and is required to be commercially free from objectionable odours, materials, and dust or other solid or liquid matter, waxes, gums and gum forming constituents, which might damage or adversely affect operation of equipment downstream of the custody transfer point. LNG carrier ships transport liquefied natural gas (LNG) across oceans, while tank trucks can carry LNG or compressed natural gas (CNG) over shorter distances. Sea transport using CNG carrier ships that are now under development may be competitive with LNG transport in specific conditions. Gas

3003-409: Is transported at high pressure, typically above 200 bars (20,000 kPa; 2,900 psi). Compressors and decompression equipment are less capital intensive and may be economical in smaller unit sizes than liquefaction/regasification plants. Natural gas trucks and carriers may transport natural gas directly to end-users, or to distribution points such as pipelines. In the past, the natural gas which

3094-416: Is turned into liquid at a liquefaction plant, and is returned to gas form at regasification plant at the terminal . Shipborne regasification equipment is also used. LNG is the preferred form for long distance, high volume transportation of natural gas, whereas pipeline is preferred for transport for distances up to 4,000 km (2,500 mi) over land and approximately half that distance offshore. CNG

3185-468: Is used for both: to contrast obligatory standards (also known as "de jure standards"); or to express a dominant standard, when there is more than one proposed standard. In social sciences , a voluntary standard that is also a de facto standard, is a typical solution to a coordination problem . Several countries, including Australia, Japan, Mexico, the United Kingdom and the United States, have

3276-763: The Afghan Parliament , approved the agreement on a gas pipeline and the day after, the Indian Cabinet allowed state-run gas-firm GAIL to sign the Gas Sale and Purchase Agreement (GSPA) with Türkmengaz , Turkmenistan's national oil company. Construction on the project started in Turkmenistan on 13 December 2015 and was completed by mid-2019. Construction on the Afghan side started on 24 February 2018. The Taliban have vowed to cooperate and not disrupt

3367-717: The Central Asia Gas Pipeline, Ltd. (CentGas) consortium for construction of a pipeline, led by Unocal, was formed. On 27 October 1997, CentGas was incorporated in formal signing ceremonies in Ashgabat , Turkmenistan, by several international oil companies along with the Government of Turkmenistan . Since the pipeline was to pass through Afghanistan, it was necessary to work with the Taliban. The U.S. ambassador to Pakistan, Robert Oakley , left his post and

Couples who are living together are generally recognised as a de facto union and thus able to claim many of the rights and benefits of a married couple, even if they have not registered or officially documented their relationship, although this may vary by state. It has been noted that it is harder to prove de facto relationship status, particularly in

The final destination of the pipeline will be the Indian town of Fazilka , near the border between Pakistan and India. Natural gas Natural gas (also called fossil gas, methane gas , or simply gas ) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) in addition to various smaller amounts of other higher alkanes . Traces of carbon dioxide , nitrogen , hydrogen sulfide , and helium are also usually present. Methane

3640-458: The World Bank has a pertinent definition: A "de facto government" comes into, or remains in, power by means not provided for in the country's constitution, such as a coup d'état, revolution, usurpation, abrogation or suspension of the constitution. In engineering, de facto technology is a system in which the intellectual property and know-how is privately held. Usually only the owner of

However, no particular variety of Chinese referred to in law is specified. Cantonese ( Hong Kong Cantonese ) in traditional Chinese characters is the de facto standard in both territories. A de facto government is a government wherein all the attributes of sovereignty have, by usurpation, been transferred from those who had been legally invested with them to others, who, sustained by

3913-427: The supply chain can result in natural gas having a similar carbon footprint to other fossil fuels overall. Natural gas can be found in underground geological formations , often alongside other fossil fuels like coal and oil (petroleum). Most natural gas has been created through either biogenic or thermogenic processes. Thermogenic gas takes a much longer period of time to form and is created when organic matter

4004-548: The 19th century, natural gas was primarily obtained as a by-product of producing oil . The small, light gas carbon chains came out of solution as the extracted fluids underwent pressure reduction from the reservoir to the surface, similar to uncapping a soft drink bottle where the carbon dioxide effervesces . The gas was often viewed as a by-product, a hazard, and a disposal problem in active oil fields. The large volumes produced could not be used until relatively expensive pipeline and storage facilities were constructed to deliver

4095-406: The 20th century, it was increasingly referred to as simply "gas." In order to highlight its role in exacerbating the climate crisis , however, many organizations have criticized the continued use of the word "natural" in referring to the gas. These advocates prefer the term "fossil gas" or "methane gas" as better conveying to the public its climate threat. A 2020 study of Americans' perceptions of

4186-426: The 20th century, the phrase de facto state of war refers to a situation where two nations are actively engaging, or are engaged, in aggressive military actions against the other without a formal declaration of war . A domestic partner outside marriage is referred to as a de facto husband or wife by some authorities. In Australian law , a de facto relationship is a legally recognized, committed relationship of

4277-614: The Asian Development Bank submitted the final version of a feasibility study designed by British company Penspen . The project has drawn strong US support as it would allow the Central Asian republics to export energy to Western markets "without relying on Russian routes". Then-US Ambassador to Turkmenistan Tracey Ann Jacobson noted, "We are seriously looking at the project, and it is quite possible that American companies will join it". Due to increasing instability,

4368-587: The District of Columbia still permit common-law marriage; but common law marriages are otherwise valid and recognised by and in all jurisdictions whose rules of comity mandate the recognition of any marriage that was legally formed in the jurisdiction where it was contracted. De facto joint custody is comparable to the joint legal decision-making authority a married couple has over their child(ren) in many jurisdictions (Canada as an example). Upon separation, each parent maintains de facto joint custody, until such time

4459-478: The Two Sicilies ). The de facto boundaries of a country are defined by the area that its government is actually able to enforce its laws in, and to defend against encroachments by other countries that may also claim the same territory de jure. The Durand Line is an example of a de facto boundary. As well as cases of border disputes , de facto boundaries may also arise in relatively unpopulated areas in which

4550-432: The US had peaked three times, with current levels exceeding both previous peaks. It reached 24.1 trillion cubic feet per year in 1973, followed by a decline, and reached 24.5 trillion cubic feet in 2001. After a brief drop, withdrawals increased nearly every year since 2006 (owing to the shale gas boom ), with 2017 production at 33.4 trillion cubic feet and 2019 production at 40.7 trillion cubic feet. After

4641-427: The US, over one-third of households (>40 million homes) cook with gas. Natural gas dispensed in a residential setting can generate temperatures in excess of 1,100 °C (2,000 °F) making it a powerful domestic cooking and heating fuel. Stanford scientists estimated that gas stoves emit 0.8–1.3% of the gas they use as unburned methane and that total U.S. stove emissions are 28.1 gigagrams of methane. In much of

4732-599: The United States (outside of the South) until the 1950s and 1960s was simply discrimination that was not segregation by law (de jure). " Jim Crow laws ", which were enacted in the 1870s, brought legal racial segregation against black Americans residing in the American South . These laws were legally ended in 1964 by the Civil Rights Act of 1964 . Most commonly used to describe large scale conflicts of

4823-523: The United States begins with localized use. In the seventeenth century, French missionaries witnessed the American Indians setting fire to natural gas seeps around lake Erie, and scattered observations of these seeps were made by European-descended settlers throughout the eastern seaboard through the 1700s. In 1821, William Hart dug the first commercial natural gas well in the United States at Fredonia, New York , United States, which led in 1858 to

4914-505: The border was never formally established or in which the agreed border was never surveyed and its exact position is unclear. The same concepts may also apply to a boundary between provinces or other subdivisions of a federal state . In South Africa, although de jure apartheid formally began in 1948, de facto racist policies and practices discriminating against black South Africans, People of Colour, and Indians dated back decades before. De facto racial discrimination and segregation in

5005-702: The bottoms of the gashouse ovens was often used for roofing and other waterproofing purposes, and when mixed with sand and gravel was used for paving streets. Huge quantities of natural gas (primarily methane) exist in the form of clathrates under sediment on offshore continental shelves and on land in arctic regions that experience permafrost , such as those in Siberia . Hydrates require a combination of high pressure and low temperature to form. In 2013, Japan Oil, Gas and Metals National Corporation (JOGMEC) announced that they had recovered commercially relevant quantities of natural gas from methane hydrate. The image below

5096-435: The case of the death of one of the partners. In April 2014, an Australian federal court judge ruled that a heterosexual couple who had a child and lived together for 13 years were not in a de facto relationship and thus the court had no jurisdiction to divide up their property under family law following a request for separation. In his ruling, the judge stated "de facto relationship(s) may be described as 'marriage like' but it

5187-586: The convicted person to "live out the vast majority of their life in jail prior to their release." A de facto standard is a standard (formal or informal) that has achieved a dominant position by tradition, enforcement, or market dominance. It has not necessarily received formal approval by way of a standardization process, and may not have an official standards document. Technical standards are usually voluntary, such as ISO 9000 requirements, but may be obligatory, enforced by government norms, such as drinking water quality requirements. The term "de facto standard"

Natural gas can be burned for heating, cooking, and electricity generation . Consisting mainly of methane, natural gas is rarely used as a chemical feedstock . The extraction and consumption of natural gas is a major industry. When burned for heat or electricity , natural gas emits fewer toxic air pollutants, less carbon dioxide, and almost no particulate matter compared to other fossil and biomass fuels. However, gas venting and unintended fugitive emissions throughout

However, his de facto rule of the nation began earlier: during his time as vice president ; he exercised a great deal of power at the expense of the elderly Ahmed Hassan al-Bakr , the de jure president. In Argentina , the successive military coups that overthrew constitutional governments installed de facto governments in 1930–1932 , 1943–1946 , 1955–1958 , 1966–1973 and 1976–1983 ,

Further such ventures followed near wells in other states, until technological innovations allowed the growth of major long distance pipelines from the 1920s onward. By 2009, 66,000 km (16,000 cu mi) (or 8%) had been used out of the total 850,000 km (200,000 cu mi) of estimated remaining recoverable reserves of natural gas. In

Natural gas can come out of the ground and cause a long-burning fire. In ancient Greece , the gas flames at Mount Chimaera contributed to the legend of the fire-breathing creature Chimera . In ancient China , gas resulting from the drilling for brines was first used by about 400 BC. The Chinese transported gas seeping from

5915-435: The gas needs to be cooled down and compressed, as the friction in the pipeline causes the gas to heat up. Many existing pipelines in the US are close to reaching their capacity, prompting some politicians representing northern states to speak of potential shortages. The large trade cost implies that natural gas markets are globally much less integrated, causing significant price differences across countries. In Western Europe ,

6006-517: The gas pipeline network is already dense. New pipelines are planned or under construction between Western Europe and the Near East or Northern Africa . Whenever gas is bought or sold at custody transfer points, rules and agreements are made regarding the gas quality. These may include the maximum allowable concentration of CO 2 , H 2 S and H 2 O . Usually sales quality gas that has been treated to remove contamination

6097-896: The gas to consumer markets. Until the early part of the 20th century, most natural gas associated with oil was either simply released or burned off at oil fields. Gas venting and production flaring are still practised in modern times, but efforts are ongoing around the world to retire them, and to replace them with other commercially viable and useful alternatives. In addition to transporting gas via pipelines for use in power generation, other end uses for natural gas include export as liquefied natural gas (LNG) or conversion of natural gas into other liquid products via gas to liquids (GTL) technologies. GTL technologies can convert natural gas into liquids products such as gasoline, diesel or jet fuel. A variety of GTL technologies have been developed, including Fischer–Tropsch (F–T), methanol to gasoline (MTG) and syngas to gasoline plus (STG+). F–T produces

6188-478: The governments of Turkmenistan and Pakistan for a pipeline project was signed. This project was promoted by Argentinian company Bridas Corporation . The U.S. company Unocal , in conjunction with the Saudi oil company Delta, promoted an alternative project without Bridas' involvement. On 21 October 1995, these two companies signed a separate agreement with Turkmenistan's president Saparmurat Niyazov . In August 1996,

The processed natural gas may then be used for residential, commercial and industrial uses. Natural gas flowing in the distribution lines is called mid-stream natural gas and is often used to power engines which rotate compressors. These compressors are required in

6461-612: The largest proven gas reserves. Sources that consider that Russia has by far the largest proven reserves include the US Central Intelligence Agency (47,600 km ) and Energy Information Administration (47,800 km ), as well as the Organization of Petroleum Exporting Countries (48,700 km ). Contrarily, BP credits Russia with only 32,900 km , which would place it in second, slightly behind Iran (33,100 to 33,800 km , depending on

The subsequent legal analysis of the validity of such actions led to the formulation of a doctrine of the de facto governments , a case law ( precedential ) formulation which essentially said that the actions and decrees of past de facto governments, although not rooted in legal legitimacy when taken, remained binding until and unless such time as they were revoked or repealed de jure by

6643-809: The legal authority to exercise power. These individuals are today commonly recorded as the "leaders" of their respective nations; recording their legal, correct title would not give an accurate assessment of their power. Another example of a de facto ruler is someone who is not the actual ruler but exerts great or total influence over the true ruler, which is quite common in monarchies. Some examples of these de facto rulers are Empress Dowager Cixi of China (for son Tongzhi Emperor and nephew Guangxu Emperor ), Prince Alexander Menshikov (for his former lover Empress Catherine I of Russia ), Cardinal Richelieu of France (for Louis XIII ), Queen Elisabeth of Parma (for her husband, King Philip V ) and Queen Maria Carolina of Naples and Sicily (for her husband King Ferdinand I of

6734-433: The natural gas can be transported. Natural gas extracted from oil wells is called casinghead gas (whether or not truly produced up the annulus and through a casinghead outlet) or associated gas. The natural gas industry is extracting an increasing quantity of gas from challenging, unconventional resource types : sour gas , tight gas , shale gas , and coalbed methane . There is some disagreement on which country has

6825-456: The pipeline was signed on 11 December 2010 in Ashgabat . However, in April 2012, India and Afghanistan have failed to agree on transit fee for gas passing through Afghan territory. Consequently, Islamabad and New Delhi too could not agree on the transit fee for the segment of the pipeline passing through Pakistan, which has linked its fee structure to any India-Afghanistan agreement. On 16 May 2012,

6916-508: The pipeline. The pipeline was intended to be operational by 2019. Originally, the cost of the pipeline project was reportedly estimated at US$ 7.6 billion, but a more recent estimate was $ 10 billion. The leading partner of the project is Türkmengaz . The 1,814 km (1,127 mi) pipeline will run from the world's second largest gas field namely Galkynysh gas fields in Turkmenistan through Afghanistan and Pakistan to India. In Afghanistan, TAPI pipeline will be constructed alongside

7007-441: The pores of the gas reservoir get depleted. One method to deal with this problem is to re-inject dried gas free of condensate to maintain the underground pressure and to allow re-evaporation and extraction of condensates. More frequently, the liquid condenses at the surface, and one of the tasks of the gas plant is to collect this condensate. The resulting liquid is called natural gas liquid (NGL) and has commercial value. Shale gas

7098-480: The project has essentially stalled; construction of the Turkmen part was supposed to start in 2006, but the overall feasibility is questionable since the southern part of the Afghan section runs through territory which continues to be under de facto Taliban control. On 24 April 2008, Pakistan, India and Afghanistan signed a framework agreement to buy natural gas from Turkmenistan. The intergovernmental agreement on

7189-491: The project in areas they control. The pipeline will be 1,420 mm (56 in) in diameter with a working pressure of 100 atm (10,000 kPa). The capacity will be 33 × 10 ^  m (1.2 × 10 ^  cu ft) of natural gas per year of which 5 × 10 ^  m (180 × 10 ^  cu ft) will be provided to Afghanistan and 14 × 10 ^  m (490 × 10 ^  cu ft) to each Pakistan and India. Six compressor stations would be constructed along

7280-585: The project's initiation was held in Turkmenistan on 13 December 2015, and practical work in Afghanistan began on 11 September 2024. Proponents of the project see it as a modern continuation of the Silk Road . In August 2024, the Foreign Minister of Turkmenistan Raşit Meredow met virtually with Mullah Abdul Ghani Baradar , Afghanistan's Deputy Prime Minister for Economic Affairs. Following this meeting, Foreign Minister Meredow "said that Turkmenistan

7371-486: The result of: a desire to simplify manufacturing processes & cost-effectiveness ( such as adopting a one size fits all approach ), consumer demand & expectation, or other factors known only to the complier. In prison sentences , the term de facto life sentence (also known as a "virtual" life sentence ) is used to describe a "non-life sentence" that is long enough to end after the convicted person would have likely died due to old age, or one long enough to cause

7462-550: The source). It is estimated that there are about 900,000 km of "unconventional" gas such as shale gas, of which 180,000 km may be recoverable. In turn, many studies from MIT , Black & Veatch and the US Department of Energy predict that natural gas will account for a larger portion of electricity generation and heat in the future. The world's largest gas field is the offshore South Pars / North Dome Gas-Condensate field , shared between Iran and Qatar. It

7553-427: The technology manufactures the related equipment. Meanwhile, a standard technology consists of systems that have been publicly released to a certain degree so that anybody can manufacture equipment supporting the technology. For instance, in cell phone communications, CDMA1X is a de facto technology, while GSM is a standard technology. Examples of a de facto General Manager in sports include Syd Thrift who acted as

7644-654: The third peak in December 2019, extraction continued to fall from March onward due to decreased demand caused by the COVID-19 pandemic in the US . The 2021 global energy crisis was driven by a global surge in demand as the world quit the economic recession caused by COVID-19, particularly due to strong energy demand in Asia. Because of its low density, it is not easy to store natural gas or to transport it by vehicle. Natural gas pipelines are impractical across oceans, since

7735-412: The transmission line to pressurize and repressurize the mid-stream natural gas as the gas travels. Typically, natural gas powered engines require 35–39 MJ/m (950–1,050 BTU/cu ft) natural gas to operate at the rotational name plate specifications. Several methods are used to remove these higher molecular weighted gases for use by the natural gas engine. A few technologies are as follows: In

7826-656: The world. Because its early forms originated in England in the Middle Ages , this is particularly true in Anglo-American legal traditions and in former colonies of the British Empire , while also playing a role in some countries that have mixed systems with significant admixtures of civil law. Due to Australian federalism , de facto partnerships can only be legally recognised whilst the couple lives within

7917-502: The worldwide extraction, access to natural gas has become an important issue in international politics, and countries vie for control of pipelines. In the first decade of the 21st century, Gazprom , the state-owned energy company in Russia, engaged in disputes with Ukraine and Belarus over the price of natural gas, which have created concerns that gas deliveries to parts of Europe could be cut off for political reasons. The United States

8008-460: Was behind those attacks, and all pipeline negotiations halted, as the Taliban's then leader, Mullah Omar , announced that bin Laden had the Taliban's support. Unocal withdrew from the consortium on 8 December 1998, and soon after closed its offices in Afghanistan and Pakistan. The new deal on the pipeline was signed on 27 December 2002 by the leaders of Turkmenistan, Afghanistan and Pakistan. In 2005,

8099-508: Was hired by CentGas in 1997. In January 1998, the Taliban , selecting CentGas over Argentinian competitor Bridas Corporation , signed an agreement that allowed the proposed project to proceed. In June 1998, Russian Gazprom relinquished its 10% stake in the project. On 7 August 1998, American embassies in Nairobi and Dar es Salaam were bombed . The United States alleged that Osama bin Laden

8190-494: Was invented in Saudi Arabia in the late 1970s, ending any necessity for flaring. Satellite and nearby infra-red camera observations, however, shows that flaring and venting are still happening in some countries. Natural gas is used to generate electricity and heat for desalination . Similarly, some landfills that also discharge methane gases have been set up to capture the methane and generate electricity. Natural gas

8281-567: Was recovered in the course of recovering petroleum could not be profitably sold, and was simply burned at the oil field in a process known as flaring . Flaring is now illegal in many countries. Additionally, higher demand in the last 20–30 years has made production of gas associated with oil economically viable. As a further option, the gas is now sometimes re- injected into the formation for enhanced oil recovery by pressure maintenance as well as miscible or immiscible flooding. Conservation, re-injection, or flaring of natural gas associated with oil
