摘要

A volume in or near a wellbore penetrating a subterranean hydrocarbon-bearing formation is plugged using a cementing gel comprising a high molecular weight, water-soluble carboxylate-containing polymer and a chromic carboxylate complex crosslinking agent. The gel components are combined at the surface and injected into the volume via the wellbore to form a continuous single-phase gel therein.
