A gas lift apparatus for use with a well bore sealing device includes a tubing string coupled to the well bore sealing device, a gas inlet port in the tubing string extending between the well bore above the sealing device and a flow bore in the tubing string to provide a first flow path, and a second flow path in the tubing string wherein the first flow bore extends the first fluid path to a location in the well bore below the sealing device and the second flow path. A method for producing a fluid from a well bore zone below a set sealing device disposed in a production tubing includes providing a gas to a well bore annulus formed by the production tubing, flowing the gas downwardly into the production tubing and then through the sealing device, flowing the gas through the well bore zone and then into the well bore zone and flowing the fluid upwardly through the well bore zone, then into the production tubing and through the sealing device to the surface of the well.
