This paper presents the results of a study of the mineral composition of rocks on the example of one of the high viscosity oil deposits. Studies were performed using X-ray diffraction analysis. Samples of both the reservoir itself, represented by bituminous sandstone, and samples of overburden and underlying formations composed of clays and limestones were studied. Samples were taken from several wells, which makes it possible to judge the variability of the mineral composition along strike. The content of clay mi...

Modeling the elastic properties of rocks may be one of the characteristics of the investigated geological section. In modeling, a connection is established between the main characteristics of the reservoir: porosity and pore shape, saturation, and mineral composition. In this article, the results of petrophysical interpretation and modeling of the elastic properties are presented on the example of sandy deposits from one of the fields in Western Siberia. At the first stage, the well with a full geophysical complex...
