Method for the in-situ treatment of hydrocarbonaceous materials

摘要: In-situ treatment of oil shale or other hydrocarbonaceous material by an inexpensive hot gaseous fluid, such as air flue gas, a heat transfer agent to volatilize kerogen matter and preferably also carrier sufficient crack fissure the make it permeable gas flow therethrough. Recovery volatilized is through one more bore holes remote from location introduction aided at least, but preferably, partial hydrogenation within localized zone between locations holes, adjoining latter.
