Method of forming a rubblized in-situ retort |
| abstract |
An in-situ retort is formed in an oil shale deposit by a sublevel caving method in which the starting slot for the sublevel caving is at opposite ends of the retort on adjacent sublevels. Any zones of high permeability that are formed adjacent to the starting slots are limited in vertical extent to the vertical spacing of the sublevels and are spaced from the zones of high permeability in adjacent sublevels by the length of the retort. A source of channeling through the retort that is caused by the usual sublevel caving mining method is thereby eliminated. |
