Abstract: The present invention relates to methods for controlling the migration of particulates, such as proppant and formation sands, from subterranean formations using solutions of tackifying materials. One embodiment of the present invention provides a method of treating a subterranean formation comprising the steps of placing a tackifying composition into the subterranean formation and then placing an after-flush fluid into the subterranean formation.

Abstract: A method of injection of a higher density fluid into the top of the annulus of a well while lower density fluid is withdrawn from the top of the annulus of the well, wherein the higher density fluid has a composition such that it will drop through the lower density fluid without dispersing therein, thus flowing into the deeper reaches of the annulus and not short circuiting through the top of the annulus to the point from which the lower density fluid is intended to be withdrawn. A method of injection of a higher density fluid into the top of the annulus of a well without simultaneously withdrawing a lower density fluid from the top of the annulus of the well, wherein the higher density fluid has a composition such that it will drop through the lower density fluid without dispersing therein, thus flowing into the deeper reaches of the annulus so that when the pressure induced in the annulus as a result of this injection is subsequently bled off, principally the lower density fluid will be that which is withdrawn.

Abstract: A method for stabilizing a subterranean formation which includes introducing a stabilizing composition into a subterranean formation, for example, by pumping into and through cracks and crevices in the formation and allowing the stabilizing compositions to cure thereby stabilizing the formation. The stabilizing composition includes a non-shrink synthetic resin, a catalyst and various additives and fillers.
