ABSTRACT:
Hydrocarbon recovery from subterranean reservoirs that are penetrated by either injector or producer wells is enhanced by selective permeability modification of the strata of the reservoir with gel-forming phenolic compositions. The injection of the phenolic composition follows a pH sequence specific to the reservoir environment which allows emplacement of the gel-forming composition the desired distance away from the wellbore and production of a uniform gel throughout the treated hydrocarbon-bearing reservoir. The permeability of a treated subterranean reservoir can be restored by treatment of the reservoir with either aqueous hypochlorite or mineral acid.
