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 ...
Different estimates may or may not include oil shale, mined oil sands or natural gas liquids. Because proven reserves include oil recoverable under current economic conditions, nations may see large increases in proven reserves when known, but previously uneconomic deposits become economic to develop.
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.
The Kupferschiefer (German for Copper Shale, Copper Schist or Copper Slate) [1] [2] or Kupfermergel (Copper Marl), (T1 or Z1) [3] is an extensive and remarkable sedimentary unit in Central Europe.
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]
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 ...
Location of the deposit on the map of France. The Autun oil shale deposit is a sedimentary basin containing oil shale of the Autunian age (between 299 and 282 million years old) in the vicinity of Autun in Saône-et-Loire, in the center-east of France. The extraction of the shale commenced in 1824 at Igornay.
In the south-west, under a prospecting permit granted by the French government in 2006, known as the "Permis de Foix", Canadian company Encana drilled two exploratory wells for shale gas in 2007, one year at Franquevielle [37] and 4 months at Mérigon. [38] The deposits were deemed insufficient for further exploitation.
