  • Reversible polymeric gelation for oilfield applications
    Patent number: 7987912
    Abstract: A subterranean location accessed via a wellbore is treated with an oilfield fluid containing a viscosifying agent which is a polymer and a cross-linking agent which can undergo the Diels-Alder reaction to form a gel. Conditions at the subterranean location alter fluid viscosity by bringing about the Diels-Alder reaction to increase viscosity or the retro Diels-Alder reaction to decrease the viscosity of the gel.
    Type: Grant

  • REVERSIBLE POLYMERIC GELATION FOR OILFIELD APPLICATIONS
    Publication number: 20090126932
    Abstract: This invention relates to the synthesis and use in oilfield applications of copolymers which can undergo the Diels-Alder reaction to form a gel. Under appropriate conditions, the retro Diels-Alder reaction can take place to provide for decreasing the viscosity of the aforementioned gel.
