More CO{sub 2} floods start up in West Texas
Oil producing companies expect carbon dioxide injection to delay, by 10--20 years, the abandonment of nearly depleted waterfloods in the West Texas area. They calculate that CO{sub 2} injection may recover at least 7--10% of the original oil in place. Some reasons producers are venturing into CO{sub 2} flooding are: (1) existing waterfloods are becoming uneconomical because of high water cuts; (2) CO{sub 2} supply infrastructure operators in West Texas are providing contracts that reduce a producers risk, this helps the economics for smaller size projects; (3) CO{sub 2} price compared to a few years ago is relatively low, now said to be in the mid-$0.60/Mscf range; (4) project development costs have fallen because industry experience over the past 10 years shows that more standard oil field equipment can be used; (5) computer CO{sub 2} flood performance predictions have improved. The paper discusses new projects, the Penwell field, West Brahaney field, South Cowden field, and CO{sub 2} supply.
