ABSTRACT:
Process and apparatus for electrohydraulic recovery of crude oil wherein an explosive, ablative electric spark is generated at or near a subsurface oil bearing formation and which generates shock waves and hydraulic waves that radiate or propogate outwardly into the formation and cause forcible migration of oil toward adjacent collection wells. Electrical energy, which is well within the load-carrying capacity of an electrical service cable extending into the well, is stored at or near the level of the oil bearing formation by a capacitor bank. A spark gap across electrodes is broken down by discharging current from an injector capacitor bank after which a current of substantial magnitude is discharged from a main capacitor bank into the broken down spark gap, thus generating the explosive spark.
