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).
A 2012 report from the European Commission states that, unlike the United States, "Shale gas production will not make Europe self-sufficient in natural gas. The best case scenario for shale gas development in Europe is one in which declining conventional production can be replaced and import dependence maintained at a level of around 60%."
The Kupferschiefer is a regional stratigraphic unit stretching across an area of 600,000 square kilometres (230,000 sq mi) in the Southern Permian Basin of north-central Europe. The unit is typically 30 to 60 centimetres (12 to 24 in) thick.
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).
Lacustrine deposits have gained more attention recently due to containing valuable source rocks of oil, coal, and uranium. Lacustrine deposits generally provide productive mining conditions but can prove challenging when underground mines are attempted due to the poor shear strength of clays and silts as well as the amount of moisture often locked in the layers due to a low permeability ...
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 ...
