Major oil shale deposits are located in the Democratic Republic of Congo (equal to 14.31 billion metric tons of shale oil) and Morocco (12.3 billion metric tons or 8.16 billion metric tons of shale oil). Deposits in Congo are not properly explored yet. [7] In Morocco, oil shale deposits have been identified at ten localities with the largest ...
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 1984 study estimated the EROEI of the various known oil-shale deposits as varying between 0.7–13.3 [42] although known oil-shale extraction development projects assert an EROEI between 3 and 10. According to the World Energy Outlook 2010 , the EROEI of ex-situ processing is typically 4 to 5 while of in-situ processing it may be even as low ...
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).
Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues). Lagerstätten are indicated by a note ( [ Note 1 ] ) in the noteworthiness column.
The geology of the Baltic Sea is characterized by having areas located both at the Baltic Shield of the East European Craton and in the Danish-North German-Polish Caledonides. Historical geologists make a distinction between the current Baltic Sea depression, formed in the Cenozoic era , and the much older sedimentary basins whose sediments are ...
In February 2013, the government of Chancellor Angela Merkel announced draft regulations that would allow for the exploitation of shale gas deposits using the same fracking techniques common in the U.S., with the exception only of wetland areas that make up just over 10% of German territory.
