The largest oil fields in belong to the West Siberian oil and gas field.\u00a0Reservoirs are terrigenous, porous.\u00a0Commercial development of both deposits has been going on since the early 1980s.\u00a0The late stage of development is accompanied by characteristic difficulties – high water cut, low well flow rates, behind-the-casing fluid flow associated with poor well cementing during their construction in Soviet times.\u00a0The pluses include the availability of all the necessary infrastructure and logistics capabilities for the transportation of oil.<\/p>\n\n\n\n
Despite many years of development, geological exploration of both the field is still underway.\u00a0Additional exploration of unexplored areas is being carried out at the field.\u00a0The field includes more than 60 reservoirs containing oil of different quality, chemical and physical properties.\u00a0At , new methods of both geological exploration, for example, reservoir forecasting, and development are being worked out: horizontal, multilateral wells are drilled, multi-stage hydraulic fracturing is carried out.\u00a0The field is characterized by a complex facies structure: one layer can contain up to 6 oil deposits that are not interconnected.\u00a0With such a structure, it is difficult to accurately determine the location of each individual deposit; drilling of a large number of exploration and production wells is required,\u00a0to cover the entire layer.\u00a0At the same time, both fields produce high-quality light oils, which do not require further complex preparation and purification from impurities.<\/p>\n","protected":false},"excerpt":{"rendered":"
