HYBRID MODEL FOR DETERMINING DUAL STRING GAS LIFT SPLIT FACTOR IN OIL PRODUCERS

Upstream oil production using dual string completion, i.e., two tubing inside a well casing, is common due AirPods Case to its cost advantage.High pressure gas is employed to lift the oil to the surface when there is insufficient reservoir energy to overcome the liquids static head in the tubing.However, gas lifting for this type of completion can
