ABSTRACT:
A process for improving the effectiveness of control pulse fracturing in a carbonate formation wherein a high energy impulse device having a metallic sheath reactive with a retarded acid is utilized in combination with a retarded acid. Upon placement of such device within a wellbore, the metallic sheath reacts with the retarded acid and generates heat which activates said acid. Afterwards, the high energy impulse device is ignited which fractures the formation and forces the activated acid into the created fractures thereby enhancing acid contact with said formation.
