Abstract
The locus of a processing zone advancing through a fragmented permeable mass of formation particles in an in situ oil shale retort in a subterranean formation containing oil shale and which generates an effluent fluid is determined by placing a halogen source in the permeable mass for providing an identifiable halogen and monitoring effluent fluid from the processing zone for presence of such halocarbon. The halogen source provides halogen at a predetermined temperature.
