Bookmark or Share- Shale gas - WikipediaShale 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.

- Natural gas - Shale, Extraction, Energy | BritannicaNatural gas - Shale, Extraction, Energy: Shale gas was generated from organic mud deposited at the bottom of ancient bodies of water. Subsequent sedimentation and the resultant heat and pressure transformed the mud into shale and also produced natural gas from the organic matter contained in it.
- What is shale gas, how is it extracted through fracking and ...What is shale gas and how much is there globally? Shale gas is a form of natural gas (mostly methane), found underground in shale rock.
- Shale gas | Clean Energy, Economic Growth & Environmental ...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 years ago as organic-rich mud at the bottom of ancient seas and tidal flats.
- What is Shale Gas? - Geology.comShale 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. Over the past decade, the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce.
