In situ oil shale retorting process using introduction of gas at an intermediate location |
| abstract |
Values are recovered from a subterranean in situ oil shale retort containing a fragmented permeable mass of formation particles by passing a measuring gas through the retort to determine the presence of a blockage in the fragmented mass. If there is such a blockage, only a portion of the fragmented mass is processed and the portion of the fragmented mass having the blockage is left unprocessed. This is effected by introducing a processing gas to the retort at an intermediate location between opposing ends of the fragmented mass and withdrawing gaseous and liquid products of processing at an end of the fragmented mass remote from such blockage. |
