Abstract

The Bazhenov formation is the analog of the Bakken formation; these formations are source rocks and contain tight reservoirs of a tectonic-hydrothermal model. The interpretation of well logs begins with the identification of the Bazhenov marker and tracing a carbonate layer within the Bazhenov formation by GR, neutron and DT logs. The thickness of this layer varies from 1 to 2 m. The next step is seismic interpretation. The creation of 2D seismic forward models is presented in this paper. In these models, the behavior of the amplitude with and without a carbonate layer was studied. These models allow tracing the sign of a carbonate layer (negative amplitude peak). The analysis of 3D seismic cube slices was performed. An amplitude map was created. The distribution of carbonate rock was detected according to this map. Thus, using this approach a thin layer was determined within the Bazhenov formation.
