Patent ID: 8905136

Claim:
A method for treating a subterranean formation penetrated by a wellbore, comprising the steps of: introducing a diverting composition into one or more fractures in a subterranean formation penetrated by a wellbore, wherein the diverting composition comprises a carrier fluid and a partially dehydrated or anhydrous borate source material that does not swell substantially when placed in contact with the carrier fluid, wherein the carrier fluid is a water-miscible non-aqueous fluid selected from the group consisting of ethylene glycol, propylene glycol, N,N-dimethylformamide, tetrahydrofuran, dichloromethane, 1,4-dioxane, dimethylsulfoxide, tetramethylenesulfone, acetonitrile, hexamethylphosphoramide, 1,3-methyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone, propylene carbonate, ethylene carbonate, and combinations thereof; and exposing the diverting composition to a sufficient amount of aqueous fluid, whereby the aqueous fluid (a) swells the borate source material to a point where it bridges the one or more fractures, and then (b), after the one or more fractures have been bridged, dissolves at least a portion of the diverting composition.
