Explosive detonation tested in hydraulically fractured gas wells
A procedure and technique for stimulating low- permeability gas reservoirs by chemical explosive fracturing was investigated by the U.S. Bureau of Mines. Two field tests were conducted in a shallow, 25-md, gas-producing sand in Osage County, Okla., in which 890 and 1,000 qt of liquid nitroglycerin were displaced into hydraulic fractures. The first test was in an open-hole completion, and the second was through perforated casing. Data obtained by caliper log, impression packers, bottomhole pressure measurements, downhole camera surveys, and open-hole tests were used to evaluate well-bore damage and production improvement. Indications were that the well completed in open hole, which was extensively fractured vertically by hydraulically treatment, responded poorly to explosive fracture stimulation. Detonation through perforated casing damaged only the joint of casing in the perforated interval. Improvement in flow capacity of this well was 40%.
