摘要： Surfactants are imbibed into Halloysite nanotubes (HNT) and the imbibed nanotubes are coated with wax on the nanotube outer surface. The wax layer prevents the surfactant from being disgorged from the HNT lumen until a triggering condition exists. Triggering conditions include contact with oil, which dissolves the wax; or exposure to temperatures above a melt transition of the wax, which causes the wax to melt. Upon exposure to a triggering condition, at least some of the imbibed surfactants are disgorged from the HNT and into the surrounding environment. The disgorged surfactants provide a conventional effect of reducing interfacial tension and changing reservoir rock wettability to enhance oil recovery. A range of surfactants and waxes are usefully employed in the compositions and methods described herein.

摘要： The present invention includes the use of anhydride compositions, including alkyl and aryl anhydrides, for use as a denmlsif&idigr;er in resolving emulsions of water and oil. In particular, the anhydride composition can be used alone or in a blend with other demulsif&idigr;ers. Suitable anhydrides suitable for the present invention include acetic and propionic, with acetic anhydride being preferred. The anhydride composition can be added directly to crude oil or other compositions to be resolved. As such, the demulsifier composition includes an anhydride, such as acetic anhydride, alone or in combination with other demulsifiers. The anhydride can be used in an amount ranging between trace and 100% by weight of the demulsifier composition.

摘要： This invention is directed to a composition comprising crosslinked expandable polymeric microparticles comprising structured polymers having labile crosslinks or having a labile core and non-labile crosslinks. The starting configuration of the structured polymers constrains the microparticle to an unexpanded volume average particle size diameter of from about 0.05 to about 5,000 microns. Labile crosslinks or the labile core of the structured polymers are subject to degradation which results expansion of the microparticle. 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.
