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 is determined by monitoring in a well extending through unfragmented formation adjacent the retort, for condition in the retort affected by the advancement of such a processing zone through the retort. Monitoring can be effected by placing means for monitoring such a condition in such a well extending through unfragmented formation adjacent the retort.
