Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH 4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems.
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
Pertamina fuel station in Bali. PT Pertamina (Persero) [a] is an Indonesian state-owned oil and natural gas corporation, headquartered in Jakarta. [2] It was created in August 1968 by the merger of Pertamin (established 1961) and Permina (established in 1957).
A 1983 geologic survey found condensate-rich gas in "reef and associated carbonate facies of Lower and Middle Miocene Age that in places exceed 1,000 ft (305 m) in thickness," [4] In 2019, a multi-disciplinary study of 16 wells in the Arun field found that the Arun Carbonate Reservoir contained 92% limestone, 5% dolomite, and 3% dolomitic limestone or other composition.
Schematic unconventional reservoir classification expressed as fluid energy vs flow potential based on initials without stimulation. Unconventional (oil and gas) reservoirs, or unconventional resources (resource plays) are accumulations where oil and gas phases are tightly bound to the rock fabric by strong capillary forces, requiring specialized measures for evaluation and extraction.
Renewable natural gas can be produced and distributed via the existing gas grid, making it an attractive means of supplying existing premises with renewable heat and renewable gas energy. Renewable natural gas can also be converted into liquefied natural gas (LNG) or compressed natural gas (CNG) for direct use as fuel in transport sector.
On 27 October 1945, President Sukarno formed Jawatan Listrik dan Gas (Bureau of Electricity and Gas) under the Ministry of Public Works and Energy with a power generating capacity of 157.5 MW. In 1958, L.J.N. Eindhoven & Co was nationalised and converted into PN Gas. [1] PGN logo before rebranding on 10 December 2021
A gas pipeline compressor station. Gas is vented by design from the seals of some gas compressor equipment. In gas fields, acquiring non-associated petroleum gas (i.e. another form of raw natural gas) is the primary financial objective, and very little is unwanted compared to the gas produced in oil fields or coal mines.
