Abstract
A method and system for producing a mixed gas-oil stream through a tubing wherein at least a portion of the gas is separated from the stream and flowed through a restriction in the tubing to cool the separated gas and reduce its pressure to thereby retain larger amounts of liquid (i.e. condensate) in the gas-oil stream which is to be produced to the surface. The separated gas is compressed downhole before it is injected into a downhole formation.
