COMPOSITIONS AND METHODS FOR CONTROLLING UNCONSOLIDATED PARTICULATES

摘要

The present invention relates to methods for stabilizing an unconsolidated or weakly consolidated zone of a subterranean formation. One embodiment provides a method of stabilizing a subterranean formation comprising the steps of placing a gelable liquid composition into the subterranean formation, wherein the gelable liquid composition is capable of forming a gelled substance after placement; and, allowing the gelable liquid composition to convert into a gelled substance that stabilizes unconsolidated or weakly consolidated particles within the subterranean formation. Another embodiment provides a method of stimulating production from a subterranean formation comprising the steps of placing a gelable liquid composition into the subterranean formation; allowing the gelable liquid composition to convert into a gelled substance; creating at least one fracture in the subterranean formation extending from the well bore, through the gelled substance, and into an untreated zone of the subterranean formation; depositing proppant into at least one such fracture.
