Evaluation of Porous Media Using Digital Core Analysis by Pore Network Modeling Method: A Comprehensive Review

Abstract

Digital rock technology has emerged as a powerful tool for analyzing reservoir rocks in the petroleum industry. Technically, Digital Rock Physics (DRP) is an effective method for determining reservoir rock properties. The article reviews the history of digital rock, from its origins in the study of porous media to its development into a practical tool for the petroleum industry. The features of digital rock are discussed, including the use of X-ray microcomputed tomography and pore-scale modeling, which allow for the analysis of rock samples at the pore-scale. The philosophy and science behind digital rock are explored, emphasizing the importance of understanding the fundamental physics of fluid flow in porous media. The applications of digital rock in the petroleum industry are discussed, including its use in reservoir characterization, fluid flow simulation, and enhanced oil recovery. The benefits and limitations of digital rock are examined, highlighting the need for careful interpretation of results and the importance of complementary laboratory techniques. The role of pore network modeling in digital rock technology is also discussed, which allows for the simulation of fluid flow in porous media at the pore-scale. Finally, the article discusses future directions for digital rock, including the development of new imaging and modeling techniques and the integration of digital rock with other data sources. Overall, digital rock technology, including pore network modeling, is a promising tool for the petroleum industry that has the potential to improve the understanding of reservoir rocks and enhance hydrocarbon recovery.
