pdf A new stratigraphic scheme of the Ryazanian-Aptian strata of the Payakh petroleum accumulation zone
An active investigation of the Payakh petroleum accumulation zone (Yenisey-Khatanga petroleum bearing area), including seismic exploration and exploration drilling in connection with the high prospects of oil and gas potential revealed the possibility to develop a new correlation scheme of the Lower Cretaceous productive layers. On the basis of the created interpretive seismic project and analysis of archival and new biostratigraphic data, a new geological model of the territory was created, the boundaries of facies zones were pointed, a common indexation of productive and promising levels was proposed. Sequence of layers of the Nizhnaya Kheta Formation belonging to Payakh petroleum accumulation zone has been brought into line with the indexation of the reservoirs of the Suzun and Vankor accumulations officially registered.

Keywords: Lower Cretaceous, new stratigraphic scheme; new geological model, common indexation of productive and promising levels, Payakh petroleum accumulation zone, Yenisey-Khatanga petroleum bearing area.
