Abstract

Summary

This study focuses on the application of rock physics modeling for the petrophysical interpretation of well log data from Field N, located in the Dnipro-Donetsk Basin. By integrating petrophysical and seismic data, the research aims to enhance reservoir characterization and identify hydrocarbon-bearing formations. The methodology involves processing well log data using Techlog software and applying various petrophysical models, such as the dual-water model and Simandoux method for hydrocarbon saturation. Results demonstrate the impact of fluid saturation on key rock properties, particularly in sandstone formations. Fluid substitution modeling using Gassmann’s method reveals significant changes in rock stiffness, with bulk density and P-wave velocity increasing by up to 8% and 8.34%, respectively, when transitioning from gas to water saturation. This highlights the importance of accurate petrophysical corrections and fluid substitution techniques in reservoir evaluation. The study identifies four prospective reservoir intervals with gas saturation up to 96%, demonstrating the potential for improved hydrocarbon exploration and production efficiency in the region.
