EOR projects, notably CO{sub 2} floods, are the next generation of recovery methods in the more mature west Texas waterfloods. Installing and operating a CO{sub 2} flood can be extremely expensive. In this paper, the authors discuss methods used to make several active CO{sub 2} floods more profitable by reducing operating costs and deferring investments. The authors' goal in studying several active west Texas CO{sub 2} floods is to determine the optimum near-term cash flow, overall project economics (rate of return, present worth, etc.), and oil recoveries. The authors developed various CO{sub 2} flood designs with a reservoir simulator by altering specific operating parameters, including the half-cycle slug size, gas/water ratio (GWR), injection schemes, and total CO{sub 2} slug sizes. The authors also assessed the impact of various economic conditions --- oil prices, CO{sub 2} prices, gas processing fees, and operating costs --- on the optimization process.
