A method and system for producing a mixed gas-oil stream wherein at least a portion of the gas is separated downhole by an auger separator which is comprised of an upstream and a downstream section. As the mixed stream flows through a converging passageway in the upstream section and gas is separated by an auger, the velocity of the stream is increased thereby reducing the temperature and pressure of the stream. This allows more of the condensate to remain with the liquids and not be separated with the gas. The liquids exit the upstream section and are produced to the surface. The separated gas flows through a diverging passageway in the downstream section where a port ion of the reduced pressure is regained before the gas either produced to the surface or compressed for downhole injection.
