ABSTRACT:
A method is disclosed for altering the permeability of a gravity override path through a subsurface earth formation resulting from hot fluid (steam) injection into the subsurface formation. The method includes adding selected sized particulate material to a foam and injecting the foam into the gravity override path to deposit the particulate material thus altering the permeability in the path. The method may include the use of a noncondensible gas in the foam as well as a variety of combinations of the hot fluid injection and foam plus particulate material injection to maximize the sweep efficiency of the hot fluid injection into the subsurface formation.
