  • Publication number: 20070281870
    Abstract: Treatment fluids comprising: an aqueous base fluid; and a stimuli-degradable gel formed by a reaction comprising a gelling agent; and a stimuli-degradable cross linking agent described by the following formula: R1-[A]-[R3—[B]—R2 wherein R1 and R2 may be the same or different, and are selected from the group consisting of: substituted or unsubstituted ethylenically unsaturated groups, N-acryl, O-acryl, acrylol, vinyl, allyl, maleimide, and derivatives or combinations thereof; A and B are optional bridging units; and R3 is a degradable group or polymer.

  • Patent number: 7216705
    Abstract: Among the methods provided are methods of treating a subterranean formation comprising placing a solid treatment chemical and a tacky polymer onto a solid substrate to create a coated solid substrate; placing the coated solid substrate into a portion of a subterranean formation; and, allowing the tacky polymer to degrade and allowing the solid treatment chemical to be released into the portion of the subterranean formation. Also provided are methods of creating a particulate pack comprising a treatment chemical in a subterranean formation comprising placing a solid treatment chemical and a tacky polymer onto a particulate to create a coated particulate; creating a slurry comprising the coated particulates slurried into a treatment fluid; placing the slurry into a portion of a subterranean formation so as to create a particulate pack; and, allowing the tacky polymer to degrade and allowing the solid treatment chemical to be released into the portion of the subterranean formation.

  • Patent number: 7093664
    Abstract: The present invention is directed to disposable composite downhole tool formed of a resin-coated fiber. The fiber is formed of a degradable polymer, such as a poly(lactide) or polyanhydride. The resin is formed of the same degradable polymer as the fiber. It chemically bonds to the fiber, thereby making a strong rigid structure once cured. The fiber may be formed into a fabric before being coated with the resin. Alternatively, the fiber is formed of a non-biodegradable material.
