Abstract:
A system and method are provided for recovering bitumen from a bitumen reserve. The method includes recovering bitumen from an alternative pay region in the bitumen reserve via gravity drainage using an inclined horizontally drilled well drilled from a drainage pit upwardly into the bitumen reserve. The drainage pit has been excavated into an area of an underlying formation that is, at least in part, adjacent to and underlying the bitumen reserve. The alternative pay region includes a region unsuitable for recovering bitumen by surface mining or by in situ recovery using wells that produce bitumen to ground level above the alternative pay region.
