1. A method of treating a subterranean formation comprising:
- providing a foamed consolidation fluid comprising;
a resin in emulsified form comprising an aqueous external phase, and an organic internal phase, and wherein the emulsified resin does not comprise a hardening agent;
a hardening agent component; and
,an emulsifying agent comprising a mixture of an amphoteric surfactant present in an amount from about 30% to about 45% by weight of the surfactant mixture and an anionic surfactant in an amount from about 55% to about 70% by weight of the surfactant mixture;
introducing the consolidation fluid into a subterranean formation comprising unconsolidated particulates; and
,curing the resin to at least partially consolidate the unconsolidated particulates.

Abstract
Method of treating a subterranean formation comprising providing a consolidation fluid, introducing the resin consolidation fluid into a subterranean formation comprising unconsolidated particulates; and, curing the resin to at least partially consolidate the unconsolidated particulates. The consolidation fluid comprises a resin in emulsified form with an aqueous external phase and an organic internal phase wherein the emulsified resin does not comprise a hardening agent and an aqueous base fluid that further comprises a hardening agent. The consolidation fluid may further comprise an emulsifying agent.
