© SGEM2018. Heavy crudes and natural bitumen might present one of the accessible energy resources for the period of time necessary for the adoption of novel energy technologies of the future. Their development is characterized ...

© SGEM2018. X reservoir is a high temperature (97 ℃), high salinity (TDS 204600 mg/L, divalent cation 11480.34 mg/L), middle-low permeability sandstone reservoir located in Tarim Basin (China). Serious vertical and lateral ...

© SGEM2018. Because of the hydrocarbon reserves reducing from traditional reservoirs in Russia, much attention is paid now to unconventional resources, such as the Domanik oil shales of the Volga–Ural Basin. The Domanik ...

© SGEM2018. The Volga–Ural petroliferous basin is the oldest oil producing region of Russia. Therefore, most of the major oil and gas fields of traditional types here are already at the final stage of production. This ...

© SGEM2018. In the conditions of the deterioration of the structure of reserves of conditioned oil, development of non-traditional sources of hydrocarbon raw materials is becoming one of the promising directions of increasing ...

© SGEM2018. Heavy crude oils are extracted mostly by thermal recovery methods which reduce viscosity of heavy oil due to destruction of associative bonds in a complex oil fluid. In a number of articles, it is proved that ...
