This paper demonstrates lessons learned on a 5-year effort to improve and enhance field-wide influences on the Central Mallett and Slaughter CO2 WAG Units. The developments on data analysis, reservoir and production engineering, and solutions in these mature units have provided the opportunity to make major impacts on recovery and production rates, operation enhancements, and cost reductions. Focus on the total reservoir and development of a framework of data included information of the reservoir, completion design, drilling and workover history, production and well-test history, logs and diagnostic analysis, and placement options. An optimum conformance solution design for each injection well and the associated offset producers was the team's vision. This ongoing work's performance and evaluation for defining successes was through a review of the operator's economic drivers for sweep improvement, reduction of CO2, and water cycling-breakthroughs.
