Abstract
A method of gravel packing a wellbore can include mixing an activator, a thickener, a crosslinker and a plurality of resin-coated proppant particulates to provide a gravel pack fluid and introducing the gravel pack fluid into a gravel pack region of the wellbore. At least a portion of the plurality of resin-coated proppant particulates can be consolidated in the gravel pack region of the wellbore to provide a consolidated gravel pack. The consolidated gravel pack can have a UCS of at least about 60 psi when formed under a pressure of about 0.01 psi to about 50 psi and a temperature of about 160° F. to about 250° F.
