Improved methods for consolidating particulates in subterranean formations wherein the particulates are consolidated using curable resins that require the use of a hardening agent in order to cure. The improved methods use an organosilane coupling agent to increase adhesion of the curable resin to inorganic surfaces, such as proppant particulates or rock surfaces, and to act as a resin hardening agent.

La présente invention concerne des procédés améliorés pour consolider des matières particulaires dans les formations souterraines. Selon les procédés, les matières particulaires sont consolidées à l'aide de résines polymérisables qui exigent l'emploi d'un agent durcisseur pour pouvoir polymériser. Ces procédés améliorés font appel à un agent de couplage de type organosilane pour augmenter l'adhérence de la résine polymérisable aux surfaces inorganiques, telles que des matières particulaires de soutènement ou des surfaces rocheuses, et pour l'utiliser comme agent de durcissement de résine.
