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 18):
A process for preparing the stable capsule dispersion of  claim 1  comprising:\n providing the capsules containing the dense liquid; \n functionalizing the capsules by adding the carbon dioxide-philic compound to the outer side of the capsule wall to create the functionalized co-polymerized capsules; and \n preparing the dispersion by adding the functionalized capsules to supercritical carbon dioxide such that the stable dispersion of capsules in supercritical carbon dioxide is achieved.
