PLUGGING AN ABANDONED WELL WITH A POLYMER GEL

摘要

PLUGGING AN ABANDONED WELL WITH A POLYMER GEL An abandoned well penetrating a subterranean formation is plugged using a 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 wellbore to form a continuous single-phase gel therein.
