Abstract:
Methods and compositions using surface chemistry and internal porosity of proppant particulates to consolidate the proppant particulates are described herein. The methods can include a method of gravel packing a wellbore. The method 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. The method can also include consolidating at least a portion of the plurality of resin-coated proppant particulates to provide a consolidated gravel pack, wherein the consolidated gravel pack has 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.
