Abstract:
A system for recovering liquids from a downhole formation and through a production tubing string, comprising:an upper lateral extending outward from a substantially vertical wellbore and into a gas cap formation;a lower lateral extending externally from the substantially vertical wellbore and into a liquid bearing formation;a downhole injector within the substantially vertical wellbore for passing formation fluids through the injector and to the production tubing string while preventing gases from passing through the injector; anda packer positioned in the substantially vertical wellbore above the downhole injector and above the gas cap formation for sealing a well annulus radially outward of the production tubing string such that gases which are prevented from entering the production tubing string by the injector are retained downhole by the packer for passing through the upper lateral and assisting in the recovery of formation fluids from the lower lateral.
