Abstract
Disclosed is a method for controlling the flame front during the in situ combustion of a subterranean carbonaceous stratum which involves monitoring the extent and movement of said flame front to determine the location of one or more segments of the flame front which exhibit unfavorable combustion characteristics, and injecting one or more gases into the vicinity of one or more of said segments to control and optimize the combustion in said segment.
