    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： A method of treating a subterranean formation including with a bactericidal fluid is provided. The method comprises the steps of: (a) continuously mixing to obtain a stream of a treatment fluid: (i) a base fluid comprising water; (ii) an aqueous solution comprising a hypochlorite having a pH equal to or greater than 7; and (iii) a pH-adjusting agent selected to be capable of lowering the pH of water to less than 7; and (b) injecting the treatment fluid into a wellbore. The step of continuously mixing the base fluid, the aqueous solution of hypochlorite, and the pH-adjusting agent is preferably under conditions and in proportions sufficient to obtain a stream of a treatment fluid having a free chlorine concentration of at least 1 ppm by weight of the water in the treatment fluid and having a pH in the range of 4-7.

    摘要： Methods of consolidating unconsolidated weak zones or formations and forming chemical casings include drilling a well bore with a drilling fluid having a pH in the range of from about 6 to 10 and that comprises water, a polymeric cationic catalyst which is adsorbed on the mineral surfaces in the weak zone, a particulate curable solid thermoset resin and a delay acid catalyst for curing the solid resin, and forming a filter cake on the walls of the well bore. The filter cake is then contacted with a treating fluid comprising a water soluble or water dispersible polymer which is capable of being cross-linked by a thermoset resin and causing the resin to be hard and tough when cured, and a water soluble or dispersible thermoset resin, whereby the treating fluid components deposit on the filter cake and the thermoset resin cures into a hard and tough cross-linked chemical casing thereon.

    摘要： Methods of treating a previously fractured bacteria contaminated subterranean formation penetrated by a well bore whereby the bacteria contamination is substantially reduced or eliminated are provided. The methods basically comprise mixing a bactericide with a fracturing fluid in an amount effective to contact and kill bacteria contained in the formation and pumping the mixture into the formation at a rate and pressure sufficient to re-fracture the formation. The re-fracturing of the formation causes the bactericide to be distributed throughout the formation and to contact and kill bacteria contained therein without adversely effecting the productivity of the formation.
