The Influence of the Bazhenov Structure on the Reservoirs Formation on Kalchinskaya Area

The Bazhenov suite sediments are one of the prospects and at the same time unique in the architecture on the Uvat area. Bazhenov suite is one of the main source rocks, seal for overlying layers, and also is independent oil reservoir at that part of area where it has anomalous structure. Complicated tectonic structure is one of the possible migration paths for overlying Neocomian sediments and perhaps it is the cause of insignificant presence of hydrocarbonate in the underlying Jurassic sediments. In this paper we present complex logging analysis, sedimentological core analysis, seismic facies analysis and dynamic 3D seismic data analysis and acoustic inversion interpretation results
