Abstract:
This invention generally relates to the field of oil recovery from reservoirs. More specifically, it relates to the recovery of oil from sandstone and carbonate reservoirs using a process for preparing a dispersion of capsules for use downhole including the steps of providing capsules containing a dense liquid, each capsule having a capsule wall defining an inner area, the capsule wall having an outer side. The capsules are functionalized by adding a carbon dioxide-philic compound to the outer side of the capsule wall. A dispersion is then prepared by adding the functionalized capsules to supercritical carbon dioxide such that a stable dispersion of capsules in supercritical carbon dioxide is achieved.

Claim (Index 1):
A stable capsule dispersion, the stable capsule dispersion comprising:\n a dispersed phase of a plurality of functionalized co-polymerized capsules,\n where each functionalized co-polymerized capsule contains a dense liquid with a density greater than that of supercritical carbon dioxide in an inner area within a capsule wall and is operable to be stably dispersed within supercritical carbon dioxide,\n where the capsule wall of each functionalized capsule defines the inner area and has an outer side functionalized with a carbon dioxide-philic compound; and \n \n a continuous phase of supercritical carbon dioxide; such that the density of the capsule dispersion is greater than the density of supercritical carbon dioxide at the same conditions and such that the viscosity of the capsule dispersion is greater than the viscosity of supercritical carbon dioxide at the same conditions.
