CA 2721948

The present disclosure is directed to compositions and methods that may be used for enhanced oil recovery, for modifying the permeability of subterranean formations and for increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations. The compositions may include, for example, expandable cross linked polymeric microparticles having an unexpanded volume average particle size diameter of from about 0.05 to about 5,000 microns and a cross linking agent content of from about 100 to about 200,000 ppm of hydrolytically labile silyl ester or silyl ether crosslinkers and from 0 to about 300 ppm of non-labile crosslinkers.

La présente invention concerne des compositions et des procédés qui peuvent être utilisés pour une meilleure récupération de l'huile, pour modifier la perméabilité des formations souterraines et pour augmenter la mobilisation et/ou le taux de récupération des fluides hydrocarbures présents dans les formations. Les compositions peuvent comprendre, par exemple, des microparticules polymères réticulées expansibles ayant un diamètre particulaire moyen en volume non expansé compris entre environ 0,05 et environ 5 000 microns et une teneur en agent de réticulation comprise entre environ 100 et environ 200 000 ppm d'agents de réticulation éther de silyle ou ester de silyle hydrolytiquement labile et d'environ 0 à environ 300 ppm d'agents de réticulation non labiles.
