The company is owned by several companies including Power Assets Holdings , State Grid Corporation of China , Cheung Kong Infrastructure Holdings and Qatar Investment Authority . It was the first company to provide electricity in Hong Kong , having run continually since
154-509: A certain extent in South Korea , remain virtually identical to traditional characters, with variations between the two forms largely stylistic. There has historically been a debate on traditional and simplified Chinese characters . Because the simplifications are fairly systematic, it is possible to convert computer-encoded characters between the two sets, with the main issue being ambiguities in simplified representations resulting from
231-481: 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
308-484: 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
385-478: A restructuring in January 1985 whereby it was forced to sell its stake in the company for HK$ 3 billion to reduce debt levels. The company is now controlled by Li Ka-shing 's Cheung Kong Holdings as part of listed company Power Assets Holdings Limited , which before February 2011 was known as "Hongkong Electric Holdings Limited". Sources of electricity generated by Hongkong Electric in 2021 Lamma Power Station
462-542: 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
539-869: Is 産 (also the accepted form in Japan and Korea), while in Hong Kong, Macau and Taiwan the accepted form is 產 (also the accepted form in Vietnamese chữ Nôm ). The PRC tends to print material intended for people in Hong Kong, Macau and Taiwan, and overseas Chinese in traditional characters. For example, versions of the People's Daily are printed in traditional characters, and both People's Daily and Xinhua have traditional character versions of their website available, using Big5 encoding. Mainland companies selling products in Hong Kong, Macau and Taiwan use traditional characters in order to communicate with consumers;
616-459: Is a 3,736 megawatts (5,010,000 hp) either ( coal -fired, or combined cycle when used alongside natural gas ). Built in 1982 as a 250-megawatt (340,000 hp) coal-fired station, it was upgraded to 600 megawatts (800,000 hp) in 1987 and to 1,350 megawatts (1,810,000 hp) by 1989. Lamma Winds operates a Nordex standard N50 800-kilowatt (1,100 hp) wind turbine with a rotor diameter of 50 metres (160 ft). Completed in 2006,
693-493: 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
770-458: 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
847-399: 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
SECTION 10
#1732772418581924-628: 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
1001-537: 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
1078-694: 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
1155-403: 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
1232-406: 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
1309-452: 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
1386-548: 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"
1463-429: 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
1540-553: Is regulated by the Ministry of Education and standardized in the Standard Form of National Characters . These forms were predominant in written Chinese until the middle of the 20th century, when various countries that use Chinese characters began standardizing simplified sets of characters, often with characters that existed before as well-known variants of the predominant forms. Simplified characters as codified by
1617-716: 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

#17327724185811694-604: 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
1771-409: 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
1848-416: 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
1925-493: The Chinese Commercial News , World News , and United Daily News all use traditional characters, as do some Hong Kong–based magazines such as Yazhou Zhoukan . The Philippine Chinese Daily uses simplified characters. DVDs are usually subtitled using traditional characters, influenced by media from Taiwan as well as by the two countries sharing the same DVD region , 3. With most having immigrated to

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 is colorless and odorless, and
2079-776: The Peak Tram and the University of Hong Kong which had formerly generated their own supplies, switched to the company's supply. In 1924 there were 1,369 street lamps lit by gas with only 469 powered by electricity. However, by 1936, few gas lamps remained. During the Japanese invasion of Hong Kong in December 1941, a number of staff at the North Point power plant held the Japanese at bay in an epic defence. Casualties from
2156-767: The People's Republic of China are predominantly used in mainland China , Malaysia, and Singapore. "Traditional" as such is a retronym applied to non-simplified character sets in the wake of widespread use of simplified characters. Traditional characters are commonly used in Taiwan , Hong Kong , and Macau , as well as in most overseas Chinese communities outside of Southeast Asia. As for non-Chinese languages written using Chinese characters, Japanese kanji include many simplified characters known as shinjitai standardized after World War II, sometimes distinct from their simplified Chinese counterparts . Korean hanja , still used to

Typefaces often use the initialism TC to signify the use of traditional Chinese characters, as well as SC for simplified Chinese characters . In addition, the Noto, Italy family of typefaces, for example, also provides separate fonts for
2310-427: 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
2387-548: 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

Following a meeting in 188_ of the Executive Council to discuss land reclamation, Bendyshe Layton suggested to Sir Catchick Paul Chater that Hong Kong acquire an electricity generator. Chater, who was to remain a director of the new Hongkong Electric Company for 37 years, took charge of raising finance for the project. The total capital of $ 300,000 was divided into 30,000 shares, half of which were offered to
2541-406: 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

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
2772-427: 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

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
2926-524: The United States during the second half of the 19th century, Chinese Americans have long used traditional characters. When not providing both, US public notices and signs in Chinese are generally written in traditional characters, more often than in simplified characters. In the past, traditional Chinese was most often encoded on computers using the Big5 standard, which favored traditional characters. However,

A second power plant was built in North Point in 1919 and a third at Ap Lei Chau in 1968 which was decommissioned in 1989. Since 1990, all HEC's electric generators have been situated at the Lamma Power Station . Hongkong Land (HKL), which owned a 34% stake in the company, underwent
3080-702: 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

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
3388-446: The eastern US in the late 19th and early 20th centuries were simple by-product coke ovens that heated bituminous coal in air-tight chambers. The gas driven off from the coal was collected and distributed through networks of pipes to residences and other buildings where it was used for cooking and lighting. (Gas heating did not come into widespread use until the last half of the 20th century.) The coal tar (or asphalt ) that collected in

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
3619-461: The fuel found that, across political identifications, the term "methane gas" led to better estimates of its harms and risks. 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
3696-435: 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 ,
3773-517: 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
3850-896: 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

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
4081-493: The inverse is equally true as well. In digital media, many cultural phenomena imported from Hong Kong and Taiwan into mainland China, such as music videos, karaoke videos, subtitled movies, and subtitled dramas, use traditional Chinese characters. In Hong Kong and Macau , traditional characters were retained during the colonial period, while the mainland adopted simplified characters. Simplified characters are contemporaneously used to accommodate immigrants and tourists, often from

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
4235-725: The mainland. The increasing use of simplified characters has led to concern among residents regarding protecting what they see as their local heritage. Taiwan has never adopted simplified characters. The use of simplified characters in government documents and educational settings is discouraged by the government of Taiwan. Nevertheless, with sufficient context simplified characters are likely to be successfully read by those used to traditional characters, especially given some previous exposure. Many simplified characters were previously variants that had long been in some use, with systematic stroke simplifications used in folk handwriting since antiquity. Traditional characters were recognized as
4312-682: The majority of Chinese text in mainland China are simplified characters , there is no legislation prohibiting the use of traditional Chinese characters, and often traditional Chinese characters remain in use for stylistic and commercial purposes, such as in shopfront displays and advertising. Traditional Chinese characters remain ubiquitous on buildings that predate the promulgation of the current simplification scheme, such as former government buildings, religious buildings, educational institutions, and historical monuments. Traditional Chinese characters continue to be used for ceremonial, cultural, scholarly/academic research, and artistic/decorative purposes. In
4389-983: The merging of previously distinct character forms. Many Chinese online newspapers allow users to switch between these character sets. Traditional characters are known by different names throughout the Chinese-speaking world. The government of Taiwan officially refers to traditional Chinese characters as 正體字 ; 正体字 ; zhèngtǐzì ; 'orthodox characters'. This term is also used outside Taiwan to distinguish standard characters, including both simplified, and traditional, from other variants and idiomatic characters . Users of traditional characters elsewhere, as well as those using simplified characters, call traditional characters 繁體字 ; 繁体字 ; fántǐzì ; 'complex characters', 老字 ; lǎozì ; 'old characters', or 全體字 ; 全体字 ; quántǐzì ; 'full characters' to distinguish them from simplified characters. Some argue that since traditional characters are often

Traditional characters still are widely used in contexts such as in baby and corporation names, advertisements, decorations, official documents and in newspapers. The Chinese Filipino community continues to be one of the most conservative in Southeast Asia regarding simplification. Although major public universities teach in simplified characters, many well-established Chinese schools still use traditional characters. Publications such as

Conversely, there is a common objection to the description of traditional characters as 'standard', due to them not being used by a large population of Chinese speakers. Additionally, as the process of Chinese character creation often made many characters more elaborate over time, there is sometimes a hesitation to characterize them as 'traditional'. Some people refer to traditional characters as 'proper characters' ( 正字 ; zhèngzì or 正寫 ; zhèngxiě ) and to simplified characters as 簡筆字 ; 简笔字 ; jiǎnbǐzì ; 'simplified-stroke characters' or 減筆字 ; 减笔字 ; jiǎnbǐzì ; 'reduced-stroke characters', as

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

The plant was designed by electrical engineer William Wickham who subsequently remained its manager until 1910. At 6:00 p.m. on 1 December 1890, 50 street lights along Queen's Road Central , Battery Path and Upper Albert Road were switched on. The lights failed on
4928-525: 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.

Characters that are not included in the jōyō kanji list are generally recommended to be printed in their traditional forms, with a few exceptions. Additionally, there are kokuji , which are kanji wholly created in Japan, rather than originally being borrowed from China. In the Korean writing system , hanja —replaced almost entirely by hangul in South Korea and totally replaced in North Korea —are mostly identical with their traditional counterparts, save minor stylistic variations. As with Japanese, there are autochthonous hanja, known as gukja . Traditional Chinese characters are also used by non-Chinese ethnic groups. The Maniq people living in Thailand and Malaysia use Chinese characters to write
5390-412: 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
5467-703: The turbine is of stall-regulated, "horizontal axis" design and is mounted up-wind. In July 2010, the company commissioned the largest commercial-scale solar power system in Hong Kong. Based on amorphous silicon thin film photovoltaic (TFPV) technology, the requisite solar panels are located on the rooftops of the main building of Lamma Power Station. Power generated is fed directly to Hong Kong Electric's 380 V electrical grid via solar inverters , distribution boards and power transmission cables. All panels are set to face south to maximise power output and are inclined at an angle of 22 degrees. With an installed capacity of 550 kilowatts (740 hp), on completion in 2011
5544-518: The ubiquitous Unicode standard gives equal weight to simplified and traditional Chinese characters, and has become by far the most popular encoding for Chinese-language text. There are various input method editors (IMEs) available for the input of Chinese characters . Many characters, often dialectical variants, are encoded in Unicode but cannot be inputted using certain IMEs, with one example being
5621-587: The words for simplified and reduced are homophonous in Standard Chinese , both pronounced as jiǎn . The modern shapes of traditional Chinese characters first appeared with the emergence of the clerical script during the Han dynasty c. 200 BCE , with the sets of forms and norms more or less stable since the Southern and Northern dynasties period c. the 5th century . Although
5698-502: 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
5775-486: Was decommissioned and its generators moved to Lamma Power Station between 1984 and 1989; HEC office tower and building is now surrounded by the South Horizons housing estate, 34 towers built by Hutchison Whampoa . Traditional Chinese characters Traditional Chinese characters are a standard set of Chinese character forms used to write Chinese languages . In Taiwan , the set of traditional characters
5852-494: 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
5929-567: 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
