摘要： An aqueous-swellable and degradable diverting system and the use of the system in treating a subterranean formation penetrated by a wellbore. The diverting system includes a carrier fluid and a partially dehydrated or anhydrous borate source material that does not swell or does not swell substantially 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. Exposure of the diverting composition to a sufficient amount of aqueous fluid swells the borate source material, bridges a desired portion of the stimulation network, and then dissolves at least a portion of the diverting composition. The diverting techniques allow for treatment in a subterranean formation to be diverted to a previously untreated portion of the formation, in particular a portion of the formation that is significantly distanced from the wellbore.

摘要： Disclosed herein is a delayed crosslinking agent. This crosslinking agent contains a borate source and a water-soluble polysaccharide. Suggested borate sources include borax, boric acid, and sodium tetraborate. Guar gum, carboxymethylhydroxypropylguar, and hydroxypropylguar are recommended water-soluble polysaccharides. The borate source is present in an amount of from about 5 to about 30% percent by weight, calculated as B.sub.2 O.sub.3, of the water-soluble polysaccharide.These delayed crosslinking agents are transported to the well site and admixed with an aqueous solution containing additional water-soluble polysaccharide. The delayed crosslinking agents re-equilibrate in the aqueous solution of the water-soluble polysaccharide. The resulting compositions are useful as fracturing fluids.
