"Digital Core" Technology and Supercomputer Computing

This article is focused on the modeling of multiphase hydrodynamic flows within "digital core" technology for the needs of the oil and gas industry. The essenc e of this technology is direct numerical simulation of the flows on the scale of the pore space of oil and gas reservoir rocks with direct resolution of the structure of this space and the dynamics of interphase boundaries. The importance of the development of high-performance computing facilities (supercomputers) for the successful implementation of this technology is emphasized. Work carried out by the Keldysh Institute of Applied Mathematics, RAS, in the field of mathematical models, computational algorithms, and their software implementation is described.
