Twofreds Field: a tertiary oil recovery project

Conference · · Proc. Annu. Southwest. Pet. Short Course; (United States)
OSTI ID:6420121
The Twofreds Delaware Sand Reservoir in Texas was discovered in 1957 and developed as a waterflood unit in 1963. By 1973, after a moderately successful waterflood, the production rate had declined to near economic limit. Carbon dioxide (CO/sub 2/) injection for oil recovery was instigated in 1974; therefore, oil recovery since 1974 represents tertiary oil recovery after waterflooding. This work discusses the actual application of CO/sub 2/ injection procedures and the field performance for the 6 year period since CO/sub 2/ injection was started. Performance to date appears successful in recovering additional oil from reservoirs of this type.
