ABSTRACT:
A metal-containing oxidizing solution is injected through wellbores which reacts in a subterranean reservoir which has naturally-ocurring reduction capacity to form a slightly soluble compound of metal having a valence of +3. Thereafter, the metal crosslinks a water-soluble polymer which is injected into the metal-containing pore volume resulting in a decreased flow in the treated portion of the reservoir.
