ABSTRACT:
A method is provided for in-situ production of oil shale wherein a network of fractures is formed by injecting liquified gases into at least one substantially horizontally disposed fracturing borehole. Heat is thereafter applied to liquify the kerogen so that oil shale oil and/or gases can be recovered from the fractured formations.
