摘要
Re-crosslinkable preformed particle gels and compositions containing, e.g., those further comprising at least one re-crosslinking agent are provided, as well as the use thereof, e.g., in methods, processes, and techniques related to enhanced oil recovery, e.g., conformance control, wherein the use of said re-crosslinkable preformed particle gels when re-crosslinked may improve hydrocarbon recovery, e.g., by improving sweep efficiency. These re-crosslinkable preformed particle gels and compositions containing are also useful in water and gas shutoff, fluid loss control, zone abandonment, water and gas coning, squeeze and recompletion, chemical liner completions and lost circulation during drilling operations and plugging during drilling and drilling completion.
