This patent describes a method for increasing the production flow from a well penetrating a geothermal reservoir from a wellhead. The method consists of: (a) continuously injecting a sufficient amount of an inert, non-condensible lift gas into the well during the production of geothermal fluids therefrom to cause a substantial fraction, or to substantially increase a preexisting fraction, of steam in the produced fluids without having to significantly reduce the pressure of the produced fluid at the wellhead; and (b) recovering increased produced fluids and the lift gas from the well.
