Shale gas - Wikipedia
Shale gas has been produced for years from shales with natural fractures; the shale gas boom in recent years has been due to modern technology in hydraulic fracturing (fracking) to create extensive artificial fractures around well bores.
Shale gas | Clean Energy, Economic Growth & Environmental …
2024年10月25日 · 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.
Shale gas in the United States - Wikipedia
Shale gas in the United States is an available source of unconventional natural gas. Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of U.S. natural gas ...

2022年2月11日 · 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.
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
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 definition, production, and uses - MET
2021年1月18日 · What is shale gas? Shale is a fine-grained, clastic sedimentary rock, composed of mud and it is a massive mineral. It is so tough that drilling into it is a rather costly process. Shale gas is hiding beneath this kind of rock, deep below the surface. There are two types of natural gas: Conventional. Unconventional.
Shale gas is having a beneficial impact on supplies and consumer prices for natural gas, as well as additional environmental benefits: Natural gas provides a quarter of overall U.S. energy; It is used to generate a quarter of the nation’s electricity.
Natural gas - Shale, Extraction, Energy | Britannica
5 天之前 · Natural 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? Basically, it is natural gas – primarily methane – found in shale formations, some of which were formed 300-million-to-400-million years ago during the Devonian period of Earth’s history.
