This paper will analyze the response of oil rate to CO2 injection in various fields worldwide including Weyburn and Joffre. Epic consulting has completed a detailed CO2 screening of all reservoirs in Alberta, Saskatchewan, Manitoba, and Ontario. The importance of using both static and dynamic screening parameters will be emphasized. Also, the concept of CO2 retention which is important for CO2 sequestration will be explored. Epic has also generated an analytical program that uses both experimental and empirical concepts to forecast the expected oil rate response to miscible CO2 injection. Results of the program will be compared to field cases. Lastly, reservoir simulation results for vertical CO2 miscible floods in Niagaran reefs in Michigan will be presented.
