Induction coil method for detecting underground flame fronts |
| abstract |
Disclosed is a method for detecting the flame front during the in situ combustion of a subterranean carbonaceous stratum which involves providing at least one multi-turn coil of wire on the surface of the ground electrically connected into one or more circuits in which an electrical resonance condition is established, and monitoring the change in impedance in one or more of said circuits as an indication of the extent and movement of said flame front. |
