Tertiary recovery potential of CO2 flooding in Joffre Viking pool, Alberta
Significant tertiary oil recovery by CO2 flooding in a watered-out Joffre Viking sand unit in central Alberta, as determined in a preliminary feasibility study, prompted further detailed evaluation of the CO2 process. Consequently, reservoir simulation models are used in the study to further investigate the technical feasibility and prediction of CO2 flood performance. Using a Black Oil simulator (BETA II), history matching of primary and waterflood production performance on a selected portion of the Joffre Viking Pool involving 85 wells was undertaken. This step provided for proper initialization of fluid and pressure distribution and a reservoir description for the miscible CO2 flood model (COMP II). Sensitivity analysis and process optimization using a typical pattern approach were conducted to optimize the tertiary CO2 flood performance. Simulation results indicated that in the presence of a trapped oil saturation due to water blocking oil from contact by the injected CO2, a larger CO2 slug and/or a smaller water slug are required in a water-alternating-with-gas process for more efficient displacements. 13 references.
