ABSTRACT:
Method for recovering bitumen from oil or tar sand using jets of hot water and/or steam introduced into the sand via raises connected to underlying spaced aprt tunnels. The jets are arcuately moved horizontally in overlapping patterns to slurry the sand. Caverns are formed by caving the tar sand and removal of the slurry into which the over burden is permitted to cave forming there above a surface depression usable as a tailing pond. Cavities are formed by other jets which connect with the priorly formed cavities so there is a continuous backward movement of interconnecting cavities.
