Waterflooding concepts in carbonate reservoirs of West Texas and New Mexico have changed drastically in recent years. The original flood designs for many waterfloods called for peripheral water injection with minimal interior injection. The use of generalized geologic correlations or averages of rock properties in the design and execution of these projects led to delayed and inefficient flood response. Review of these drive projects, particularly with a more precise geologic definition, led to the conclusion that closer-spaced, more regular flood patterns would be necessary to enhance ultimate oil recovery.
