"Composition And Method For Recovering Hydrocarbon Fluids From A Subterranean Reservoir"
Abstract: This invention is directed to a composition comprising expandable polymeric microparticles comprising hydrophobic polymers having a backbone with labile pendant groups, the microparticles having an unexpanded volume average particle size diameter of from about 0.05 to about 50 microns. The starting configuration of the hydrophobic polymers constrains the microparticle to an unexpanded volume average particle size diameter of from about 0.05 to about 50 microns. Labile pendant groups on the backbone are subject to hydrolysis under a change in environmental conditions that results in release of the expandable microparticle so that the microparticle expands. The invention is further directed to the use of the composition for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.
