A METHOD, A SYSTEM AND AN APPARATUS FOR IN SITU PROCESSING OF AN OIL SHALE FORMATION
A method, system and apparatus using injection (124) and producer (128) wells to create underground fluidised bed retort systems (110). A cavern (118) for the retort system (110) may be created without the use of explosive mining methods, conventional fracking or other fragmentation methods. The cavern (118) and the fluidised bed (120) are created by the use of high pressure injection jets of pure hot hydrogen gas (H2) and steam upon an oil shale rock (112).
