ABSTRACT:
An apparatus in which a casing pipe closed at both its ends extends from the surface of the earth into a formation producing geothermal brine. The casing pipe contains a string of pipe of lesser diameter extending through the closed ends of the casing pipe thereby forming an annular conduit between the pipes. The casing pipe contains openings that are located to be situated in the upper portion of the producing formation. The string of pipe is open at its lower end, is terminated at its upper end outside the casing pipe with a means for controlling flow, and contains a means for separating brine from vapor. The means for separating brine from vapor has means for discharging liquid into the annular conduit and for passing vapor into the portion of the string of pipe downstream of the separating means. In operation, geothermal brine passes through the string of pipe to the separating means with dry steam passing into the portion of the string of pipe downstream of the separating means and brine from which the steam has been separated returning to the producing formation by way of the annular conduit. Back pressure is maintained on the produced steam using a flow control means on the string of pipe.
