1. A method for consolidating unconsolidated particulates, the method comprising:
introducing a furfuryl alcohol-based resin treatment fluid into a wellbore; wherein the furfuryl alcohol-based resin treatment fluid comprises:
a furfuryl alcohol-based resin, and
a diluent;
contacting the unconsolidated particulates within the wellbore with the furfuryl alcohol-based resin treatment fluid to form resin-contacted unconsolidated particulates;
introducing 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 comprises:
a substituted amine acid salt; wherein the substituted amine acid salt is the reaction product of an alkanolamine and a mineral acid, and
a solvent; and
contacting the resin-contacted unconsolidated particulates with the substituted amine acid treatment fluid.
