ABSTRACT:
A method for conducting an in situ combustion process in a hydrocarbon-bearing subsurface geologic formation wherein water and essentially pure oxygen are injected into a well at essentially the same time but physically separated from one another so that a combined hot water/steam and in situ combustion drive is set up in the formation for the tertiary recovery of hydrocarbons therefrom.
