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