Method of obtaining oil from oil shale deposits
Patent
·
OSTI ID:6430353
The present method involves the initial mining of horizontally extending layers of oil-rich or ''kerogen phase continuous'' shale. The oil-rich shale is brought to the surface where it is retorted in above-ground retorts of one of the known types. The leaner oil shale which is still ''in situ'' is then explosively fragmented into the voids created when the oil-rich shale was mined, and oil is obtained as the fragmented shale is ignited, in accordance with known horizontal type modified in situ oil shale retorting techniques.
