Method for operating an in situ oil shale retort having channelling |
| abstract |
An in situ oil shale retort contains a fragmented permeable mass of formation particles containing oil shale and has a primary combustion zone advancing through a first region having a first fluid flow path, and a second region having a second fluid flow path. The first and second paths have different gas permeabilities. An oxygen containing retort inlet mixture is introduced to the fragmented mass for advancing the primary combustion zone through the fragmented mass and for flow of gas along the first and second flow paths. n To maintain a substantially flat primary combustion zone, gas flowing through the first fluid path is maintained at a first average temperature and gas flowing through the second fluid path is maintained at a sufficiently different average temperature to provide substantially equal rates of advancement of the combustion zone through the fragmented mass in the first and second regions. n This can be effected by maintaining the temperature, composition, and/or oxygen mass flow rate of gas introduced to the first region different from the temperature, composition and/or oxygen mass flow rate of gas introduced to the second region. |
