Abstract:
A method for the recovery of oil from a subterranean, viscous oil-containing formation by injecting steam into the lower portion of the formation, simultaneously injecting water into the formation to build up the pressure of the formation to about 300 psia, maintaining the formation pressure at about 300 psia during the steam drive, and producing oil from the upper portion of the formation.
