ABSTRACT:
A method of recovering hydrocarbon from a hydrocarbon-bearing formation by the use of steam in which after the steam is injected into the formation a material is injected which will cause the production of a condensable foam blocking zone so that the well can be put into production and during said production much of the steam will be maintained in the formation until the foam condenses, thereby providing more efficient use of the heat in the steam.
