摘要： A method is disclosed for drilling a wellbore employing a drilling fluid providing the advantages of easy pumpability of a low viscosity fluid with the drill cuttings suspension capability of a highly viscous fluid. The viscosity of the fluid is also easily and quickly adjustable so that the fluid rheology may be adapted during drilling as the subterranean conditions change. These advantages are obtained by including in said fluid a reversibly crosslinkable polymer and an encapsulated crosslink activator. The crosslink activator causes crosslinking after the fluid is in the wellbore. The crosslinking is reversed at the well surface to reduce the viscosity of the fluid to enable the drill cuttings to be easily removed. Crosslink activator is added back to the fluid and the fluid is returned to the borehole. The amount of crosslink activator and/or crosslinkable polymer may be adjusted in the fluid to change the fluid rheology to conform the fluid to changes in the well conditions as monitored real time.

摘要： A gel fluid for treating a subterranean formation penetrated by a well bore including an aqueous liquid, an organic gelling agent and at least about 0.05% by weight, based on the weight of the aqueous liquid, of a broken gel fragment stabilizer. The gel fluid can optionally include crosslinking agents, proppant materials, pH buffers and other components. The broken gel fragment stabilizer is a dialkyl sulfosuccinate that has dispersing properties sufficient to diminish the propensity of broken gel fragments formed when the gel fluid breaks to agglomerate. Also provided is a method of treating a subterranean formation penetrated by a well bore. The inventive gel fluid and method are particularly suitable for fracturing a subterranean formation to stimulate the production of hydrocarbons therefrom.

摘要： A method of fracturing a subterranean formation with a stabilized foamed fracturing fluid comprising from about 30 percent to in excess of about 95 percent by volume of carbon dioxide with the remainder comprising a substantially anhydrous liquid and a selected surfactant. The foam is formed in situ by injection of a stabilized liquid-liquid emulsion containing liquid carbon dioxide into a well bore penetrating the formation. The temperature and pressure of the emulsion is controlled to maintain the carbon dioxide in the liquid phase during injection into the well bore. Thereafter, the carbon dioxide is heated by the subterranean formation to a temperature above about 88.degree. F. at which time the stabilized emulsion spontaneously forms a high quality stabilized foam.
