摘要：
Disclosed is a method for detecting the flame front in the in situ combustion of a subterranean carbonaceous stratum which comprises providing two or more resistance probes inserted into the ground electrically connected in one or more circuits capable of measuring the resistance between pairs of said probes, and monitoring the change in resistance in one or more of said circuits as an indication of the extent and movement of said flame front.
