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 CO , flooding , CO , 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 .
