摘要： Disclosed herein are methods that include a method for treating a well bore including treating a subterranean formation with a first treatment fluid, wherein the first treatment fluid treats a first treated zone. A degradable diverting material may then be introduced into the subterranean formation. The subterranean formation may be treated with a second treatment fluid where the degradable diverting material diverts at least a portion of the second treatment fluid away from the first treated zone.

摘要： The present invention provides seawater-based cross-linked fracturing fluids and methods of preparing and using the fluids in fracturing subterranean formations penetrated by well bores and having temperatures above about 200° F. The improved cross-linked fracturing fluids are basically comprised of a gelling agent, seawater present in an amount sufficient to hydrate the gelling agent and to form a gelled aqueous fluid, and a delayed cross-linking agent, capable of causing delayed cross-linking of the gelling agent in the gelled aqueous fluid at a pH below the threshold for precipitate formation in seawater.
