Petroelastic modeling application for predicting the collectors distribution according to 3D seismic survey data in the Yuzhno-Danilovskaya area
The paper is devoted to the use of petroelastic modeling for predicting the reservoirs distribution according to 3D seismic survey data in the Yuzhno-Danilovskaya area in the deposits of the Danilovskaya, Tyumen Formation and weathering crust. In the framework of the theoretical model, curves are obtained that allow identification of the distribution areas of collectors and non-collectors according to well logging data. The Gassman model helped to determine the ranges for predicting oil and gas-saturated interlayers. The petroelastic model allows a qualitative and quantitative description of the elastic parameter limits in which the reservoir properties of the rocks can manifest themselves.
