ABSTRACT:
An uncased wellbore penetrating a subterranean hydrocarbon-bearing formation is sealed by forming a gel at the open wellbore face 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 wellbore to form the continuous single-phase gel in situ.
