Abstract
The article considers the conditions of forming D0 formation within the field on the western slope of the South Tatar arch. Based on the description of core material from wells, as well as on the conclusion of GSW, a lithological map has been constructed with the allocation of facies zones within the license boundary of the studied deposit; zones of sandy islands (coastal-marine situation), facies of the shelf zone and facies transitional to deep-water are distinguished here. The results of testing of production wells in various facies zones are also considered; the highest inflows are obtained from wells drilled in the zone of coastal-marine sediments.

Materials and methods
For writing this article, the authors used samples of core material to isolate structural lithological features and study fauna; as well as GSW conclusions on wells to assess the content of clay component in the D0 formation and subsequent mapping of facies zones within the studied deposit.
