Shale gas - Wikipedia
One of the byproducts of shale gas exploration is the opening up of deep underground shale deposits to "tight oil" or shale oil production. By 2035, shale oil production could "boost the world economy by up to $2.7 trillion, a PricewaterhouseCoopers (PwC) report says.
Shale gas in the United States - Wikipedia
In 1996, shale gas wells in the United States produced 0.3 trillion cubic feet (8.5 billion cubic metres), 1.6% of US gas production; by 2006, production had more than tripled to 1.1 trillion cubic feet (31 billion cubic metres) per year, 5.9% of US gas production.
Shale gas by country - Wikipedia
Most of the shale gas about 3.66 trillion cubic meters is in the Baltic Sea Basin, about 1.25 trillion cubic meters within the region of Lublin province, followed by 0.4 trillion cubic meters in the Podlaskie province. 2012 estimates by the Polish Geological Institute put recoverable reserves at only around 350–750 billion cubic meters, [86 ...
What is shale gas, how is it extracted through fracking and ...
2022年2月11日 · Shale gas is a form of natural gas (mostly methane), found underground in shale rock. It is classified as ‘unconventional’ because it is found in shale, a less permeable rock formation than sandstone, siltstone or limestone in which ‘conventional’ gas is found, and it is generally distributed over a much larger area.
Producible portions of shale gas formations are located many thousands of feet below the surface, well below groundwater aquifers. Modern hydraulic fracturing technology involves sophisticated engineering processes designed to create distinct fracture networks in …
Shale gas: a step toward sustainable energy future
2021年4月17日 · Shale gas is one of the unconventional sources of energy. Shale gas deposits are scattered all over the planet in low-permeability and low porosity reservoirs. India has overall reserves of shale gas between 600 and 2000 TCF, of which 63 TCF is of recoverable shale gas (Pradhan and Prakash 2000).
Shale gas | Clean Energy, Economic Growth - Encyclopedia Britannica
Shale gas, natural gas obtained from sheetlike formations of shale, frequently at depths exceeding 1,500 metres (5,000 feet). Shales are fine-grained sedimentary rocks consisting of silt- and clay-sized particles that were laid down hundreds of millions of …
Shale gas - British Geological Survey
Shale gas is natural gas found in shale deposits, where it is trapped in microscopic or submicroscopic pores. This natural gas is a mixture of naturally occurring hydrocarbon gases produced from the decomposition of organic matter (plant and animal remains).
Natural gas from shale formation – The evolution, evidences …
2014年2月1日 · Shale gas is in shale deposits, which are typically found in river deltas, lake deposits or floodplains. Shale is both the source and the reservoir for the natural gas. This can either be “free gas” which is trapped in the pores and fissures of the shale rocks, or adsorbed gas which is contained in surfaces of the rocks
Shale gas in the UK - British Geological Survey
Shale gas deposits are regarded as commercially exploitable when the organic matter contained within the shale is of the right type — of marine origin — the net shale thickness exceeds 25 m and when it is found at a depth of more than 1500 m.
