A new and improved method of producing hydrocarbons from a subterranean oil shale formation containing heat-sensitive carbonates comprising penetrating said formation with at least one well and forming a cavern therein so that communication is established between the surface and the cavern; circulating a hot fluid preferably in the upper region of the cavern to effect decomposition of the carbonates to carbon dioxide thereby causing pressure build-up resulting in fracturing and/or rubbling and enlarging the cavern upward to a desired dimension; terminating this process by injecting, preferably simultaneously, into the upper region of the cavern a cooling fluid and into the rubblized zone of the oil shale a kerogen pyrolyzing fluid to effect hydrocarbon recovery.
