  • Patent number: 8905136
    Abstract: 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.

  • Patent number: 8887816
    Abstract: A downhole tool or a component thereof may comprise a plasticized polymer composition that comprises a polymer and a water-soluble plasticizer, wherein the plasticized polymer composition has a first deflection test value. The tool may be exposed to an aqueous-based medium where the water-soluble plasticizer may leach out of the tool such that the plasticized polymer composition has a second deflection test value after exposure to the aqueous-based medium that is less than about 10% of the first deflection test value.

  • Patent number: 8720568
    Abstract: Disclosed herein are swellable and degradable sand plug systems used in wellbores and methods for using the systems in treating wellbores. The slurry composition includes a carrier fluid and a granular borate source material, where the borate source material is at least partially dehydrated or anhydrous. The carrier fluid may be non-aqueous fluid or, in some compositions, an aqueous fluid. The slurry composition is allowed to settle in a horizontal wellbore and at least partially fill at least a portion of the wellbore in a direction vertical to the wellbore, and is exposed to a sufficient amount of aqueous fluid to expand and substantially fill at least a portion of the wellbore, thereby plugging the wellbore. The slurry composition may be exposed to a sufficient amount of aqueous liquid to at least partially dissolve the expanded slurry composition, thereby at least partially removing the plug from the wellbore.

  • Patent number: 8720555
    Abstract: A method for diverting fluids across a perforation tunnel in high-rate water pack operations may include providing a wellbore extending into a subterranean formation, wherein a perforation tunnel provides a fluid connection between the wellbore and the subterranean formation; providing a diverting particulate that comprises a degradable plasticized polymer coating on a particulate; placing the diverting particulate into the perforation tunnel, wherein the step of placing the diverting particulate forms a particulate pack within the subterranean formation and the perforation tunnel; allowing the degradable plasticized polymer coating to deform and fill the interstitial spaces within the particulate pack in the perforation tunnel such that the fluid conductivity between the wellbore and the subterranean formation is substantially blocked; and allowing the plasticized polymer coating to degrade over time thereby substantially restoring the fluid conductivity between the wellbore and the subterranean formation.

  • Publication number: 20130233546
    Abstract: When performing subterranean treatment operations, it can be desirable to temporarily divert or block fluid flow by forming a degradable fluid seal. Methods for forming a degradable fluid seal can comprise: providing a sealing composition comprising: a degradable polymer, and a water-soluble material comprising a first portion and a second portion of rigid particulates, each portion having a sealing time and a particulate size distribution associated therewith, the particulate size distributions of the first portion and the second portion differing from one another; determining an amount of the first portion relative to the second portion needed to produce a degradable fluid seal having a desired sealing time that is different than that of the sealing time of either the first portion or the second portion; introducing the sealing composition into a subterranean formation; and allowing the sealing composition to form a degradable fluid seal in the subterranean formation.
