Sedimentological control of the cretaceous deposits petroleum potential within the Russko-Chaselskiy ridge (Western Siberia)
Most of hydrocarbon resources of Russko-Chaselskiy ridge is associated with reservoirs of Pokur Formation. It is composed generally of alluvial sandstones and shales. Due to genesis Pokur reservoirs have complex structure and localized spread within ancient alluvial plains. Performed integrated interpretation of well and 3D seismic data allowed to estimate new perspective fields and to geometrize oil and gas pulls.
