West Welch Unit is one of four large waterflood units in the Welch Field in the northwestern portion of Dawson County, Texas. The Welch Field was discovered in the early 1940`s and produces oil under a solution gas drive mechanism from the San Andres formation at approximately 4800 ft. The field has been under waterflood for 30 years and significant portion has been infill-drilled on 20-ac density. A 1982-86 pilot CO{sub 2} injection project in the offsetting South Welch Unit yielded positive results
