Abstract

The paper presents results of the geological and reservoir modeling of the Yamashinskoye field Vereiskian reservoirs. The fluidal model was matched for production history, and the results of history matching were used to predict key performance indicators. The results of history matching and the calculated production performance demonstrate good agreement between the numerical model and the actual development target. Hydrodynamic calculations included the effect of EOR/IOR operations in the forecast development period. The model shows that by the end of development, the distribution of specific mobile oil in reservoirs with common contact is more uniform compared to the lithologically screened reservoirs. By the end of development, the oil displacement efficiency in reservoirs with common contact is by 4% higher vs. the lithologically screened reservoirs, which can be explained by greater propagation of moving contacts in the former case.

Key words:

field, pay zone, structural framework, geologic cross-section, geological and reservoir (fluidal) model, mobile oil reserves, oil displacement efficiency, residual oil saturation, history matching, water injection, cumulative oil production, oil production rate
