D'Souza, A; Friedmann, F

This patent describes a process for the recovery of oil from a petroleum reservoir by improving steam sweep efficiency during steam-flooding, wherein a foaming agent is added to divert steam to unswept zones and the reservoir is penetrated by at least one injection well and at least one production. It comprises injecting steam and a surfactant solution comprising the foaming agent into an injection well, while concurrently and separately injecting an additional amount of liquid water into the injection well to generate a foam and thereby increase the pressure at the injection well; and recovering oil from a production well.
