Results of comprehensive studies of a structure heterogeneity of an upper part of Pokur Formation at an oil and gas field at a middle part of East Siberia are presented. Features of a structure of upper Pokur layers are defined by conditions of sedimentation, controlling a large homogeneous sandy packs mostly formed in a delta channels, silty–clayey deposits - in a marshy–boggy environments. Revealed in a course of lithofacies researches features of a structure are a reliable geological basis for a heavy oil production intensification methods projection of a heterogeneous layers of an upper part of Pokur formation.
