Optimizing oil recovery has been a combined effort of many engineering disciplines in the Shell-operated Denver unit of the Wasson San Andres field of Gaines and Yoakum counties, Texas. Rising market demand and increased oil allowables provided the impetus for full-scale infill drilling, major injection system expansion and active remedial efforts. Maintaining high producing and injection efficiency required concentrated production engineering and field operations' work. Areas of specific activity are well completions, the injection system, flood surveillance, and workovers. The Denver unit is the largest of 5 waterflood pressure maintenance projects in this field discovered in 1936. The unit currently contains 664 oil producing wells and 238 water injection wells. Production is from the Permian San Andres dolomite formation at an average total depth of 5,200 ft. Gross pay thickness is from 300 to 500 ft. Production and performance curves are shown. A graphical representation shows the completion and acid treatment program for producers and injection well to maximize oil recovery.
