Abstract

The present invention generally relates to the composition of particle gels for CO-EOR and COstorage. More particularly, COresistant particle gels are provided that can re-crosslink at subterranean conditions. These particle gels can be deployed to improve the conformance of COflooding, COhuff-puff, or Water-Alternative-Gas (WAG). The applications may also involve COstorage, such as the blocking of COleakage and similar COprocessing.
