Examination of clastic oil and gas reservoir rock permeability modeling by molecular dynamics simulation using high-performance computing

Abstract

“Digital rock” is a multi-purpose tool for solving a variety of tasks in the field of geological exploration and production of hydrocarbons at various stages, designed to improve the accuracy of geological study of subsurface resources, the efficiency of reproduction and usage of mineral resources, as well as applying of the results obtained in industry. This paper presents the results of numerical calculations and their comparison with the full-scale natural examination. Laboratory studies have been supplemented with petrographic descriptions to deepen an insight into behaviors of the studied rock material. There is a general tendency to overestimate the permeability, which may be associated with the application of a rather crude resistive model for assessing permeability and owing to the porous cement has not been considered.
