The above production history shows the effect of the application of an emerging Electrically Enhanced Oil Production (EEOP) technology to a California Heavy Oil Field.
The pay zone of this field an approximately 100 ft thick unconsolidated sand at a depth of approximately 3,200 ft below the ground surface (bgs). The first 30 days of the above production history established the baseline or background production rate of 5 BOPD (heavy green line) 8.1° API gravity crude, with a 45% water cut and 1,750 - 2,000 SCFGPD gas with a 1,197 BTU/SCF produced gas energy content (PGEC) and 2,290 ppm H2S.
After 5 days of EEOP operation, production rate jumped to an average value of approximately 50 BOPD (heavy magenta line) 9.4° API gravity crude, with a 12% water cut and 3,800 SCFGPD gas with a 1,730 BTU/SCF PGEC and 4 - 40 ppm H2S.
After 24 days of this elevated performance, the well sanded up and the operator was unable to salvage the well.
