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 ...
Location of the kukersite deposits within the Baltic Oil Shale Basin in northern Estonia and Russia. The Baltic Oil Shale Basin covers about 3,000 to 5,000 square kilometres (1,200 to 1,900 sq mi). [1] [5] [6] [7] Main kukersite deposits are Estonian and Tapa deposits in Estonia, and Leningrad deposit in Russia (also known as Gdov or Oudova ...
A 1984 study estimated the EROI of the various known oil-shale deposits as varying between 0.7–13.3, [75] although known oil-shale extraction development projects assert an EROI between 3 and 10. According to the World Energy Outlook 2010, the EROI of ex-situ processing is typically 4 to 5 while of in-situ processing it may be even as low as 2.
The Messel lake bed was probably a center point for drainage from nearby rivers and creeks. A fossil of the primitive mammal Kopidodon, showing outline of fur. The pit deposits were formed during the Eocene Epoch of the Paleogene Period about 47 million years ago, based on dating of basalt fragments underlying fossilbearing strata. [6]
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 ...
The Posidonia Shale (German: Posidonienschiefer, also called Schistes Bitumineux in Luxembourg) geologically known as the Sachrang Formation, is an Early Jurassic (Early to Late Toarcian) geological formation of southwestern and northeast Germany, northern Switzerland, northwestern Austria, southern Luxembourg and the Netherlands, including exceptionally well-preserved complete skeletons of ...
The fine particles that compose shale can remain suspended in water long after the larger particles of sand have been deposited. As a result, shales are typically deposited in very slow moving water and are often found in lakes and lagoonal deposits, in river deltas, on floodplains and offshore below the wave base. [13]
