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.
