摘要： Methods and compositions for sealing subterranean zones having temperatures in the range of from about 80° F. to about 300° F. are provided. A method of the invention is basically comprised of the steps of providing a subterranean zone sealing composition that becomes substantially rigid when exposed to subterranean zone temperatures above about 80° F. and has a pH above about 8.5 comprised of water, a substantially fully hydrated depolymerized polymer and a cross-linking agent. The sealing composition is introduced into the subterranean zone whereby it becomes rigid and seals the zone. The sealing composition can subsequently be removed by contact with a fluid having a pH below about 8 when a boron compound is utilized as the cross-linking agent.

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.
