Аннотация:Sedimentologic analysis of cores from wells sunk in the Vankor petroleum field allowed refinement
of the accumulation conditions producing the sandy strata of the Lower Het River (Nizhnekhetsky) Formation
accumulated in the coastal marine zone and of the Yakovlevo (Yakovlevsky) Formation accumulated under alluvial–
deltaic conditions. Petrographic examination of the sandstones added information on the sources, transport,
and accumulation conditions of the terrigenous material in the northeastern marginal part of the West Siberian
sedimentation basin.
