Abstract
Summary
On the basis of litho-facial studies both lithofacies and depositional environments have been distinguished in the Lower-Middle Jurassic deposits of the Yugansk zone of the Western Siberia. Detailed analysis of core material showed that sedimentation occurred mainly in the conditions of alluvial plain in the extreme North-Western and Eastern parts of the territory turning to the upper delta plain occasionally flooded by the sea. High properties reservoirs are associated with facies point bars of straight channels, delta channels and crevasse splays.
