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 ...
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]
Cases of long distance oil migration into shallow traps away from the "generative depressions" are usually found in foreland basins. Besides pointing to zones of high petroleum potential within a sedimentary basin, subsurface mapping of a source rock's degree of thermal maturity is also the basic tool to identify and broadly delineate shale gas ...
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.
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 ...
The rocks of the Michigan Basin are the source of commercial quantities of petroleum. The most actively drilled-for source of natural gas in recent years has been shale gas from the Devonian Antrim Shale in the northern part of the basin. The Michigan basin extends into Ontario, Canada, where oil and gas regulators are studying its potential.
Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Oil shales can be classified by their composition (carbonate minerals such as calcite or detrital minerals such as quartz and clays) or by their depositional environment (large lakes, shallow marine, and lagoon/small lake settings).
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 ...
