Western Siberia is the center of the oil industry in Russia, which determines the economic state of the country and is the largest oil and gas basin in the world. Of the 65 largest oil fields of Russia, 49 are confined to the West Siberian basin. The resource potential of the West Siberian oil and gas basin has always attracted researchers. To date, there is a huge experience in forecasting, prospecting and exploration of oil and gas reservoirs in the basin, many scientific papers have been published related to the development of the territory. In any period of time, the topical issue facing specialists will be the increment of reserves that are profitable for development and the localization of residual oil and gas reserves. To date, active prospecting and exploration work is underway, focused on complex constructed objects, mainly used for non-anticlinal and combined traps at great depths, because of there is a shortage of prospective reserves and resources of anticlinal structures. Under these conditions, the study of the Achimov horizon of the West Siberia region becomes especially promising.

Key words: Western Siberia, Ob river area, lithology, regional geology, Achimov sequence, anticlinical, reserves and resources, sedimentary conditions, rock-collector, stage conditions, sedimentation, reservoir properties, cuneiform, oil and gas basin
