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 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.
U.S. shale oil and natural gas maps - U.S. Energy Information ...
The following maps show the drilling history and oil and gas production of selected low-permeability, continuous-type shale reservoirs. Selected geologic characteristics pertinent to occurrence of producible oil and gas resources are also shown when available.

Life After 5: How Tight-Oil Wells Grow Old - JPT
2020年1月31日 · The average decline rate of horizontal wells in the Eagle Ford Shale at age 5 is about 23.5%—the highest such figure of the three major onshore oil plays in the US. At age 5, the average well in the play produces 28 B/D.
Marcellus natural gas trend - Wikipedia
The natural gas is trapped in low-permeability shale, and requires the well completion method of hydraulic fracturing to allow the gas to flow to the well bore. The surge in drilling activity in the Marcellus Shale since 2008 has generated both economic benefits and considerable controversy.

Marcellus Shale: Results Continue to Amaze Geologists
Twenty years ago, every geologist involved in Appalachian Basin oil and gas knew about the Devonian black shale called the Marcellus. Its black color made it easy to spot in the field, and its slightly radioactive signature made it a very easy pick on a geophysical well log.
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 …
Chevron Shale and Tight Resources
Natural gas wells that produce from shale rock are expected to have a long production life, spanning several decades. A valuable source of energy for homes and businesses, vehicles, power generation, and other industrial processes, natural gas production brings social as well as economic benefits.
