    摘要： Methods of consolidating formations or forming chemical casing or both while drilling are provided. One method of the invention comprises drilling a well bore with a drilling fluid comprised of water, a polymeric cationic catalyst which is adsorbed on weak zones or formations formed of unconsolidated clays, shale, sand stone and the like, a water soluble or dispersible polymer which is cross-linked by a thermoset resin and causes the resin to be hard and tough when cured, a particulate curable solid thermoset resin, a water soluble thermoset resin, and a delayed dispersible acid catalyst for curing the solid and water soluble resins. The drilling fluid forms a filter cake on the walls of the well bore that cures and consolidates the unconsolidated weak zones and formations penetrated by the well bore so that sloughing is prevented and forms a hard and tough cross-linked chemical casing on the walls of the well bore.

    摘要： Methods comprising: providing an aqueous treatment fluid comprising an aqueous fluid, a friction reducing polymer, and an antiflocculation additive; and introducing the treatment fluid into a subterranean formation. Methods of fracturing a subterranean formation comprising: providing an aqueous treatment fluid comprising an aqueous fluid, a friction reducing polymer, and an antiflocculation additive; and introducing the treatment fluid into a well bore penetrating the subterranean formation at rate in the range of from about 30 barrels to about 250 barrels per minute so as to create or enhance one or more fractures in the subterranean formation. Aqueous treatment fluids comprising: an aqueous fluid, a friction reducing polymer in an amount sufficient to reduce friction without forming a gel, and an antiflocculation additive.
