As a result of waterflooding, an additional 19 million bbl of oil is expected to be recovered from the uppermost pay zone of the Loco Hills-Grayburg-San Andres Pool in Eddy County, N. Mex., demonstrating the feasibility of waterflooding many shallow fields in New Mexico. A pilot- cooperative area in Loco Hills has been flooded on a new 80-acre, 5 spot pattern, contrived mainly by converting producers to injection status, which will probably be retained throughout the flood program. A limited water source is available, and most injection water is transported to the area by pipeline from the Lea County Fresh Water Basin, some 35 miles away. A map shows the flooded areas at Loco Hills. A chart shows the injection- production performance of the waterflood operation. Although breakthrough occurred on the pilot-cooperative project shortly after production response, it has not affected recoveries or sweep efficiency. The reservoir is a stratigraphic trap with approximately 500 ft of relief and a regional drop of 100 ft per mile to the E. Average depth to top of pay is 2,600 ft.
