Methodology for Quantifying the Heterogeneity of the Distribution of Oil Saturation in Terrigenous Reservoir Rocks
https://doi.org/10.18599/grs.2025.1.8
Abstract
The article presents lithological studies of reservoir rocks of terrigenous deposits of the Lower Cretaceous of the Krasnoleninsky arch of Western Siberia. A distinctive feature of these deposits is the high variability of lithotypes, which is expressed in a wide range of textural features of the
deposits that determine the nature of oil saturation. According to the results of textural analysis, it was revealed that the studied sediments were formed in various zones of underwater channels of the delta complex and lagoons. To assess the total number of oil-saturated reservoir rocks and the degree of
their stratification, 10 models were selected that allow us to characterize the distribution of oil-saturated reservoir rocks in different facies complexes. The methodology developed at Gubkin University at the Department of Lithology made it possible to quantify the heterogeneity of the distribution of oil saturation in the multifacial deposits of the Lower Cretaceous of the Krasnoleninsky arch.
