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 19):
The process according to  claim 18 , where the step of providing the capsules comprises:\n providing a first liquid, the first liquid having a density greater than the density of supercritical carbon dioxide, adding a first monomer to the first liquid to create a first monomer-liquid composition; providing a second liquid, the second liquid operable to form a liquid phase when combined with the first liquid; adding a second monomer to the second liquid to create a second monomer-liquid composition; adding the first monomer-liquid composition to the second monomer-liquid composition; agitating the first monomer-liquid composition and the second monomer-liquid composition to create a dispersion of first monomer-liquid composition in the second monomer-liquid composition; and allowing the first and second monomers to diffuse and to co-polymerize at a liquid-liquid interface at a pre-determined time such that co-polymerized capsules are formed encapsulating the first liquid.
