Rapid decline rates (60 to 80%/yr) in wells in the Conger-Penn field in Sterling County, Texas, have prompted Dorchester Exploration Corp. to try its first foam frac jobs on the Canyon Sand formation at 7000 to 7500 ft. Since Nov., the fracs have been performed on 3 wells: the Terry No. 31-4, the Terry No. 18-4, and the R.T. Foster No 11-4 in the southern portion of the field. Although it is still too early to tell whether the dramatic production drops have been arrested, personnel involved in the program seem pleased with the foam technique. The purpose behind Dorchester's experimentation in this region is to decrease the amount of fluid that conventional frac jobs leave in the tight sand formation. The advantages of using foam fracs in this area are discussed.
