In nature simultaneous manifestation of several processes takes place: diffusion and filtration of hydrocarbons, their emergence, overflows along tectonic fractures, etc. Other things being equal, the dispersion of gas accumulations occurs much faster than oil accumulation, due to greater mobility (migration ability) gases, better solubility in water, higher diffusion capacity, etc. All these natural processes that can lead to the redistribution or destruction of oil and gas accumulations take place mainly over a ...

In order to exclude the unprofitability of heavy oil deposits development in Russia and abroad, it is necessary to search and create new more advanced technologies for heavy oil and bitumen deposits development aimed at improving and creating technologies for increasing oil recovery, which allow developing fields with the greatest economic efficiency. This is due to both the structure of "unconventional" oil reserves and the need for more complete production of hydrocarbon reserves with sufficient high production ...
