Experience of oil-saturated cube simulation in reservoirs, heterogeneous in their reservoir characteristics, at the latest stage of their development
The paper presents a method of oil-saturation cube simulation in reservoirs with heterogeneous filtration characteristics. The dependence of the change of a reservoir water-saturation coefficient on the reservoir characteristics and marks relative to the pure water table for the conditions of Alkeevskaya area of Romashkinskoye field is obtained as well. It is established that application of this method of the oil-saturation cube simulation allowed a more reliable estimation of the initial geological oil reserves within D1 formation of Alkeevskaya area of Romashkinskoye field and an increase of the degree of convergence of the hydrodynamic model adaptation to the development history.
