Special features of the facies distribution of neocomian sediments exemplified by the BS10 2 zones (northern part of the Surgut arch)
On the basis of thorough areal correlation, core study results and seismic and facies analysis lithologic and facies modeling for the northeastern part of the Surgut Arch was performed. The model for the formation of the silt-to sand-sized neocomian sediments of the BS10 zones was constructed. Sedimentological criteria for the distribution of high-permeability reservoirs and hydrocarbon traps in the northeastern part of the Surgut Arch are revealed.
