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 ...

Some of the most promising areas for the extraction of heavy oil, maltha and asphalt in the eastern part of the Siberian platform are the southern and southeastern slopes of the Anabar anteclise. Using solvents for mining heavy oil and natural bitumen in a permafrost zone is the only option to steam injection, which is obviously cost ineffective there. Advantages of the solvents include convenience of transportation to field and storage stability. Moreover, the solvents have sufficiently high solubility with respe...

In the article the authors propose a gradual abandonment of the outdated practice of early/urgent importation of energy resources to remote settlements and industrial facilities. Marked the main directions of studies in the perspective of transition from a research and development level to a level of industrial application. Examined the nature of gas hydrates decomposition with the purpose of developing a modern technology of transportation and storage of natural gas and its components in the hydrated state. Advan...

Within the eastern Siberian platform are known objects worth mentioning from the standpoint of organizing the extraction of heavy oil and bitumen. The Siberian platform is characterized by a wide spreading of the surface-bearing and shallow-lying rocks saturated with products of hypergenic oil conversion. The article describes the results of lithologic and petrographic studies of bitumen-saturated carbonate rocks of Anabar anteclise southern slope (Daldyno-Alakit region). The upper part of the section of the sedim...

Drilling in permafrost is accompanied by a risk of specific complications related to the disturbance of temperature conditions. The risk imposes certain restrictions on the use mud motors, depths of installation of conductor pipe and surface casing, temperature of the circulation fluid, timing of cement curing etc. This article discusses a technology of additional reaming and reciprocating the wellbore just before running casing, which is based on the properties of cryogenic rocks. Conducted an analysis of technic...
