Paper: RESULTS OF RELATIVE-PERMEABILITY MODIFIER COMBINATION USED FOR FRACTURE-STIMULATION TREATMENTS

This paper discusses field results of a fracture-stimulation treatment that includes a relative-permeability modification (RPM) chemical agent. The design objective was for the RPM to leak off into portions of the created fracture during the stimulation treatment and help prevent water production. Initial treatments were performed in April 1997 in the Brushy Canyon formation in southeastern New Mexico. The selected candidates treated were in the Delaware sand reservoir. Previous fracture treatments in this interval had resulted in water cuts greater than 60%, and the continued production of these wells had been uneconomical because of the presence of damaging scale and a subsequent decline in total fluid production; the water cuts would remain at 60 to 70%, but the total fluid production would decline.
