Patent

CA 2337122

The present invention provides a method of treating a subterranean formation with a particulate laden fluid whereby particulate flowback is reduced or prevented while also providing a controlled release of a treatment chemical within the formation. The method includes the steps of providing a fluid suspension including a mixture of a particulate, a tackifying compound and a treatment chemical, 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 tackifying compound retards release of at least a portion.
