Abstract: The present invention is directed to systems and methods for initiating annular obstructions in wells used in, or in support of, enhanced oil recovery operations-particularly enhanced oil recovery (EOR) efforts involving steam injection (e.g., steam flooding). In at least some instances, system and method embodiments of the present invention utilize one or more passively-activated annular obstruction devices (and/or hybrid active/passive devices) for inducing annular obstruction, wherein the associated passive or hybrid activation is at least partially controlled by thermal means such that it can be deemed to be thermally-directed or thermally-controlled. Such thermally-directed passive activation can afford considerably more control over the annular obstruction process and, correspondingly, over the overall steam injection into the formation and associated reservoir-thereby providing more efficient recovery of hydrocarbons.

Abstract: The present invention relates to a preparation method for a biodegradable polymer microparticle and a microparticle prepared by the method. More particularly, the present invention relates to a method for preparing a polymer microparticle, wherein the method includes the steps of: dissolving a biodegradable polyester-based polymer in DMSO (Dimethyl Sulfoxide); spraying the solution in a low temperature hydrocarbon solution to provide a frozen DMSO microparticle; adding the microparticle in a low temperature salt aqueous solution to dissolve DMSO; and removing salt. The present invention provides a method for preparing a novel polymer microsphere which can be injected through a syringe due to excellent physical properties (such as biocompatibility, biodegradability, porosity, mechanical strength) and the microcarrier's size-adjustability, and can be easily mass-produced. The microparticle prepared by the method of the present invention may have variable sizes with biodegradability and biocompatibility, and thus can be used as a carrier for regeneration of a damaged cell or tissue by being injected into a body through a syringe.
