摘要： Diverting compositions for treating a subterranean zone substantially distanced from a wellbore, comprising: a carrier fluid; and a particulate, partially dehydrated or anhydrous borate source material that does not substantially swell when placed in contact with the carrier fluid. The carrier fluid is capable of carrying and placing the borate source material into a stimulation network substantially distanced from a wellbore, and wherein the borate source material is dissolvable through sufficient contact with an aqueous fluid. 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.

摘要： Methods and compositions using gel compositions in treatment fluids employed in subterranean operations. A method includes providing a degradable gel precursor as a solid or dispersion in which substantially all the water has been removed, the degradable gel precursor being formed by a combination of a monomer and a degradable crosslinking agent of formula R1-[A]-[R3]—[B]—R2, wherein R1 and R2 may be the same or different, and includes at least one group selected from a substituted or unsubstituted ethylenically unsaturated group, N-acryloyl, O-acryloyl, vinyl, allyl, maleic anydride, a derivative thereof, and a combination thereof, A and B comprise optional bridging units, and R3 comprises a degradable group or polymer, the method including placing the degradable gel precursor in an aqueous base fluid thereby forming a treatment fluid which includes a degradable gel, and placing the treatment fluid into a subterranean formation.
