Observation of geological structure reveals productive Jurassic deposits in the Rybalny oil field, suggesting potential hydrocarbons in Lower Cretaceous sediments.
The work is devoted to the study of the geological structure features of the Jurassic deposits of the Rybalny oil field located in the Tomsk region. The base for the study was 2D, 3D seismic survey data and deep drilling materials from exploration and production wells. Deposits of the J3 formed in the transitional region of sedimentogenesis, as well as sand layers of the upper subformation of the Tyumen Formation, are productive there. In addition, we assume that deposits of hydrocarbons may be detected in the Lower Cretaceous sediments.
