ABSTRACT:
An apparatus and method for stimulating a flow from a geothermal well. A primary or stimulating fluid flows into the space between the inner and outer casings of the well. The primary fluid enters the inner casing through a series of valves at various elevations along the geothermal well casings. In one of the preferred embodiments the valves are responsive to the velocity of the primary fluid at the face of the valve to control the rate of fluid flow into the inner casing .
