The study deals with a problem of upscaling data which was obtained from the microscopic study of objects on a macroscopic scale. To investigate this issue we use the concept of 'representative elementary volume' (REV). ...

X-ray computed microtomography investigated filtration-capacitive characteristics of core sand Ashalchinsk reservoirs series. To simulate the flow of a viscous fluid in the pore scale we use a mathematical model, which ...

© 2018, Pleiades Publishing, Inc. The results of numerical simulation of the processes of two-phase flow through a porous medium in three-dimensional digital models of the porous space of three natural sandstone samples ...

At present, the coefficient of porosity is traditionally determined by the method of Preobrazhensky and by the results of a petrophysical interpretation of well log data. However, there are many examples of the significant ...
