At 301 billion metric tons, as estimated in 2005, the oil shale deposits in the United States are the largest in the world. There are two major deposits: the eastern US deposits, in Devonian-Mississippian shales, cover 250,000 square miles (650,000 km 2); the western US deposits of the Green River Formation in Colorado, Wyoming, and Utah, are ...
A map of 48 shale basins in 38 countries, based on US Energy Information Administration data, 2011. This is a list of countries by recoverable shale gas based on data collected by the Energy Information Administration agency of the United States Department of Energy. [1]
The largest deposits are found in the remains of large lakes such as the deposits of the Green River Formation of Wyoming and Utah, USA. Large lake oil shale basins are typically found in areas of block faulting or crustal warping due to mountain building. Deposits such as the Green River may be as much as 2,000 feet (610 m) and yield up to 40 ...
Shale gas is an unconventional natural gas produced from shale, a type of sedimentary rock.Shale gas has become an increasingly important source of natural gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia.
A 2016 estimate of global deposits set the total world resources of oil shale equivalent of 6.05 trillion barrels (962 billion cubic metres) of oil in place. [6] Oil shale has gained attention as a potential abundant source of oil. [7] [8] However, the various attempts to develop oil shale deposits have had limited success. Only Estonia and ...
Approximately 30% of the world's oil is found in these shale deposits. Although the origin of these deposits is still under study, it has been established that the shale routinely overlies glacial and glacio-marine sediment deposited ~445 million years before the present by the Hirnantian glaciation. The shale has been linked to glacial ...
Larger map shows the locations of Messel primates 1–7 (Table 1) within the Messel oil shale excavation. The current surface of the Messel pit is roughly 60 m (200 ft) below the local land and is about 0.7 km 2 (0.27 sq mi) in area. The oil-shale bed originally extended to a depth of 190 m (620 ft).
Some statistics on this page are disputed and controversial—different sources (OPEC, CIA World Factbook, oil companies) give different figures. Some of the differences reflect different types of oil included. Different estimates may or may not include oil shale, mined oil sands or natural gas liquids.
