CA 2288560

The present invention provides a method of treating a subterranean formation with a particulate laden fluid whereby particulate flowback is reduced or prevented. The method includes the steps of providing a fluid suspension including a mixture of a particulate, a tackifying compound and a multifunctional material, pumping the suspension into a subterranean formation and depositing the mixture within the formation whereby the tackifying compound retards movement of at least a portion of the particulate within the formation upon flow of fluids from the subterranean formation and said multifunctional material subsequently reacts with said tackifying compound to consolidate at least a portion of said particulate within said formation.
