METHODS OF FRACTURING SUBTERRANEAN ZONES TO PRODUCE MAXIMUM PRODUCTIVITY

摘要

Methods of fracturing subterranean zones to produce maximum hydrocarbon productivity are provided. The methods are basically comprised of providing a fracturing fluid comprised of water, a gelling agent present in an amount in the range of from about 0.06 % to about 0.3 % by weight of the water and an inorganic salt for preventing clay swelling present in an amount in the range of from about 0.01 % to about 1 % by weight of the water. The fracturing fluid is introduced into the subterranean zone at a rate and pressure sufficient to form fractures and the fracturing fluid is recovered from the zone.
