ABSTRACT:
A method of recovering crude oil and other hydrocarbon values from a subterranean formation which comprises generating "bottom hole pressure" within the formation by introducing an aqueous solution of a polymeric complex capable of releasing active hydrogen under the temperature and pressure conditions of the formation. Preferably, the polymeric complex is an inorganic multimetal polymeric complex in which the active hydrogen is at least partially in the form of a group selected from --NH, --PH, and --SH.
