ADAPTATION OF THE ELASTOPLASTIC FILTRATION MODEL FOR UNSTABLE RESERVOIRS (FOR THE CONDITIONS OF THE WEST PALVANTASH FIELD)

It is well known that as reservoir pressure decreases, the rock framework undergoes elastoplastic deformation. Since carbonate reservoirs are less susceptible to this process compared to clastic reservoirs, this study focuses on modeling elastoplastic filtration processes. An elastoplastic filtration model for unstable reservoirs has been adapted to the conditions of the Western Palvantash field, specifically for the drainage reserves of Horizon III, which are associated with clastic reservoirs. The calculations are based on real data obtained from the Western Palvantash field.
