Shale gas - Wikipedia
Shale gas is an unconventional natural gas that is found trapped within shale formations. [1] Since the 1990s a combination of horizontal drilling and hydraulic fracturing has made large volumes of shale gas more economical to produce, and some analysts expect that shale gas will greatly expand worldwide energy supply. [2]
What is shale gas, how is it extracted through fracking and ...
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.
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 …
What is Shale Gas? - Geology.com
What Is Shale Gas and Why Is It Important? Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas. Horizontal Drilling and Hydraulic Fracturing
Shale gas: Will it become a new type of clean energy in China? — …
2021年4月20日 · Shale gas is an unconventional natural gas that exists in organic-rich mud shale and its interlayer, mainly in the form of adsorption or the free state. Composed of methane, shale gas is a clean and efficient energy resource (Li et al., 2016). The production of shale gas drives the world’s natural gas production growth (EIA, 2016).
