US Patent 11884878 Substituted amine acid salt activation of furfuryl alcohol-based resins

Methods and fluids for consolidating unconsolidated particulates. An example method introduces a furfuryl alcohol-based resin treatment fluid into a wellbore; wherein the furfuryl alcohol-based resin treatment fluid is a furfuryl alcohol-based resin and a diluent. The method contacts the unconsolidated particulates within the wellbore with the furfuryl alcohol-based resin treatment fluid to produce resin-contacted unconsolidated particulates. The method further introduces a substituted amine acid treatment fluid into the wellbore after the introduction of the furfuryl alcohol-based resin treatment fluid into the wellbore; wherein the substituted amine acid treatment fluid is a substituted amine acid salt and a solvent. The method further contacts the resin-contacted unconsolidated particulates with the substituted amine acid treatment fluid.
