Abstract
A method is provided whereby continuous injection of lift gas into a producing geothermal well, preferably from a liquid-dominated reservoir, increases production flow of geothermal fluids from the well by initiating a steam distillation effect within the wellbore. Apparatus is also provided for continuously injecting the lift gas during production from the well.
