Major deposits are located in the Volga-Petchyorsk province and in the Baltic Oil Shale Basin. Other major oil shale deposits in Europe are located in Italy (10.45 billion metric tons of shale oil), Estonia (2.49 billion metric tons of shale oil), France (1 billion metric tons of shale oil), Belarus (1 billion metric tons of shale oil), Sweden ...
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 ...

In 2007, shale gas fields included the No. 2 (Barnett/Newark East) and No. 13 (Antrim) sources of natural gas in the United States in terms of gas volumes produced. [ 22 ] A study by MIT says that natural gas will provide 40% of America's energy needs in the future, from 20% today, thanks in part to the abundant supply of shale gas. [ 23 ]
The Kupferschiefer comprises black shales, bituminous marls, mudstones and limestones deposited mostly in an open marine setting, with the borders of its extension deposited in a shallow marine environment. At time of deposition, the area what is now northern Europe was covered by an enclosed sea; the Zechstein sea, characterized by anoxic ...
Oil shale lies at a depth of 66–600 m and deeper. The layer thickness of oil shale deposits is usually 0.1–3.7 m, and the average heat content is 6.7 MJ/kg. Belarusian oil shale was formed in Late Devonian and Early Carboniferous periods. [15] The southeastern part of Belarus has many small oil fields.
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 ...
