SMALL PLC REVAMPS PRODUCTION BATTERY CONTROL
Michael A. Argo ARCO Oil & Gas Co. Midland For a West Texas oil production facility, installation of a PLC (programmable logic controller) increased operator information, improved control system reliability, and enhanced throughput. The new controls also reduced nuisance alarms, repair time, and the possibility of spills. The H.T. Boyd production battery, located 45 miles north of Denver City, Tex., was built in 1958. Today, the battery serves 68 wells and handles 9,600 b/d of fluid.
