摘要:
A process of making a foamed conformable material by reaction injection molding comprises providing a first component from a first feed tank at a first flow rate, via a first conduit, to a mixing device; providing a second component from a second feed tank at a second flow rate, via a second conduit, to the mixing device, the second component reactive with the first component in the presence of a foaming agent; mixing the first component and the second component in the mixing device to form a reaction mixture; introducing the reaction mixture into an injection molding device; molding the reaction mixture to form a foamed conformable material; wherein the mixing of the reaction mixture is adjusted to achieve a desired average cell size of the foamed conformable material. The process can produce wellbore-conforming materials that can function to filter out sand or other undesirable fines from a formation.

摘要:
A downhole fluid separation assembly, including a body having greater affinity to a first fluid than a second fluid. The body is operatively arranged with openings for enabling fluid flow therethrough. A member is included that is movable with respect to the body and operatively arranged to compress a section of the body adjacent to the member for urging fluid out of the body and toward a target location. The body is configured to expand when not adjacent to the member for enabling fluid to reenter the body. A method of separating fluids is also included.
