Abstract
A method for identifying the location of the extent of travel of a combustion front following an in situ oil recovery operation employs a source of seismic energy and at least one seismic receiver for detecting seismic reflection signals from boundaries between subterranean formations on either side or opposite sides of such location. The properties of these seismic reflection signals are changed by the reduction in water saturation in the oil reservoir caused by the drying effect of the combustion front, and any such change is detected as an identification of the location of the extent of travel of the combustion front through the oil reservoir.
