The present invention generally relates to the composition of particle gels for conformance control, well drilling and well treatments. More particularly, this invention relates to swellable polymer particle gels that can re-crosslink, i.e., reassociate and self-heal, at subterranean conditions. These particle gels can be deployed to improve the conformance of water flooding of especially matrix bypass events (MBEs), that are also known as void space conduits. Moreover, these particle gels can be deployed for controlling the water production and increasing of petroleum recovery. The inventive particles can also be deployed as diverter for well stimulation.

Re-crosslinkable particle for conformance control and temporary plugging

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.
