ABSTRACT:
Method and Apparatus for injection steam of know quality into a subterranean reservoir containing hydrocarbon fluids, to enhance or stimulate production of said fluids through a production well. Production stimulating steam from a pressurized source is injected into the reservoir by way of a critical flow venturi and an injection well, in a manner to maintain the steam at a desired pressure and flow rate. The venturi's constricted throat is formed as a function of the stimulating steam's original characteristics.
