Abstract
A method and apparatus for the enhanced recovery of hydrocarbon fluids from subterranean reservoirs using cryogenic fluids. Using the Earth's geothermal energy to warm cryogenic flood fluids injected into subterranean reservoirs, the pressure within the subterranean reservoir is increased. This rise in pressure due to the injection of the cryogenic fluid leads to the production of fluids from to the subterranean reservoirs.
