Abstract: The present invention generally relates to the field of conformance control in oil fields, particularly to a re-crosslinkable preformed particle gel system, and composition thereof. The composition of the re-crosslinkable preformed particle gel system contains monomers, crosslinkers, a polymer matrix, and additives. Components in the composition for re-crosslinkable preformed particle gel in the present invention have excellent compatibility with each other, and the obtained gel has excellent long term high-temperature resistance property. Different from prior products, in the re-crosslinkable preformed particle gel compositions according to embodiments of the present invention, the components that are used to re-crosslink the particle gels may be grafted on the polymer chain and will act as initiator or secondary crosslinker in different conditions. During particle injection process, all compositions would move together, thereby avoiding chromatographic problems typical of prior products.

Abstract: Compositions of swellable non-toxic hydrogels and their use in conformance control are described herein. More specifically, the present invention generally relates to the hydrogels compositions that can be used to treat the oil reservoirs having high temperature and high salinity conditions. The compositions generally comprise a plurality of swellable particles having one or more crosslinkers interspersed within a polymer matrix. The compositions can also be used in biomedical, agricultural, fracking and similar applications wherein thermally-stable, nontoxic hydrogels are required.

Abstract: The present invention generally relates to the composition of particle gels for CO2-EOR and CO2 storage. More particularly, CO2 resistant particle gels are provided that can re-crosslink at subterranean conditions. These particle gels can be deployed to improve the conformance of CO2 flooding, CO2 huff-puff, or Water-Alternative-Gas (WAG). The applications may also involve CO2 storage, such as the blocking of CO2 leakage and similar CO2 processing.
