pdf Forecast of petroleum reservoir rock distribution in the Lower Cretaceous abyssal strata (western part of Yenisey-Khatanga regional depression)
A new seismostratigraphic model of Gydan and Taimyr peninsulas junction zone was created. The model is based on a regional project model, archival and new geological and geophysical data: seismic information, well-logging and biostratigraphic survey results. In the course of the studi clinoform reflecting horizons were correlated and divided into paleoelements. A new methodic of clinoform cycle main elements delineation was applied: paleo-shelf edges and paleo-slope bottoms are traced. Cretaceous abyssal strata distribution zones are localized, their cumulative gross thickness of western part of Yenisey-Khatanga regional depression was mapped. Forecast of reservoir rock distribution in the Lower Cretaceous abyssal section within the survey area performed on the basis of the gross thickness scheme and well-logging data.

Keywords: Lower Cretaceous strata, clinoform cycle, abyssal strata, gross thickness scheme, Yenisey-Khatanga regional depression.

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.
