Cyclicity, sedimentation environments and the influence of post-sedimentary processes on the structure and formation of the Vanavara Formation reservoir (based on the analysis results of core material of the Novo-Yudokon field)

Abstract

The Lower Vendian oil and gas bearing play is one of the main ones in the Siberian platform and dominant within large tectonic elements (Nepa-Botuoba anteclise, Sayan-Yenisei syneclise, etc.). The oil and gas content of the complex is determined both by the conditions of its formation and by post-sedimentation processes, which are largely associated with the stages of formation and reformation of hydrocarbon pool. All these features of Vanavara reservoir were explored in a detailed lithofacies analysis of the core material of the Novo-Yudokon field and adjacent territories.
