Abstract

New geological and geophysical models of pre-Jurassic stages in West Siberia based on log data, CMP reflection and refraction profiling, and DSS shed more light on the Paleozoic and Triassic evolution of the region. The structure of Paleozoic and Triassic formations, reinterpreted on the basis of new evidence, suggests their high petroleum potential.
