Shale gas is one of a number of unconventional sources of natural gas; others include coalbed methane, tight sandstones, and methane hydrates. Shale gas areas are often known as resource plays [27] (as opposed to exploration plays). The geological risk of not finding gas is low in resource plays, but the potential profits per successful well ...
According to U.S. Energy Information Administration estimates published in June 2013, the total Bazhenov shale prospective area has a resource of a risked tight oil in-place of 1,243 billion barrels (1.976 × 10 11 cubic metres) and a risked shale gas in-place of 1,920 trillion cubic feet (54 trillion cubic metres), with 74.6 billion barrels (1 ...
The Karoo Basin is large, extending across nearly two-thirds of the country, with the southern portion of the basin potentially favorable for shale gas. However, the basin contains significant areas of igneous sill intrusions that may impact the quality of the shale gas resources, limit the use of seismic imaging, and increase the risks of ...
The deposit is one of the world’s highest-grade deposits with more than 40% organic content and 66% conversion ratio into shale oil and gas. The oil shale is located in a single calcareous layer 2.5 to 3 metres (8.2 to 9.8 ft) in thickness and is buried at depths from 7 to 100 metres (23 to 328 ft). [6]
It is well known as the host rock for major deposits of shale oil and shale gas. The large oil discovery in the Vaca Muerta Formation was made in 2010 by the former Repsol-YPF . [ 1 ] The total proven reserves are around 927 million barrels (147.4 × 10 ^ 6 m 3 ), [ 2 ] and as of 2014 YPF 's production alone was nearly 45,000 barrels per day ...
US shale gas basins, 2011. 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.
