Abstract

​

Geological and reservoir flow models have been built for the carbonate Bashkirian and Vereiskian reservoirs of the Kurmanayevskoye oil field. The geological model was built using the ROXAR’s modeling system IRAP RMS. The grid size was 0.4 m, the same for both simulated targets. The dynamic model was built using the ROXAR’s Tempest 7.2. software. To model the geology of carbonate reservoirs, J-curve was used. Upscaling was not performed. The model was history matched using the available production data. Carter-Tracy aquifer model was used to consider for aquifer performance (effect of marginal and bottomhole water). Using the production history matching results, the forecast reservoirs performances considering production enhancement operations were calculated. The paper presents the maps of mobile oil reserves of the Kurmanayevskoye oil field throughout the field production life. The expected oil recovery factor in the recommended development option is 0.244/
