Mining and retorting of oil shale
Patent
·
OSTI ID:6974247
Oil shale is retorted in situ by drilling a pilot hole through a shale bed, pull-through mining the shale to form a retort, and retorting the shale in situ. Lean shale is mixed with richer shales to obtain uniform retorting of the adjacent shale which forms the retort, as well as retorting of the shale within the retort. (7 claims)
