Knowledge of pore characteristics is essential for understanding of microscale processes that affect the performance of oil recovery technologies. In the present research effort, the study of pore space structure has been conducted with application of tomographic imaging of core samples followed by creation of a numerical model to determine rock characteristics. Studies were conducted with core samples extracted from two intervals (1444.0 – 1449.0 and 1496.0 – 1502.0) of the Vishnevo-Polyanskoye oil field. Results of core studies provided expected capillary pressure drops due to surfactants.
