Claim 0:
1. A device for lifting a reservoir fluid in an oil and gas well, the device comprising a tubular member for forming a portion of a production tubing disposed in the well, wherein the tubular member defines an internal flow path for flow of the reservoir fluids in an axial uphole direction and comprises:
(a) a Venturi profile having a transverse cross-sectional area that gradually decreases in the axial uphole direction to a throat, the Venturi profile configured to flash out a free gas phase from the reservoir fluid as the reservoir fluid flows in the axial uphole direction through the Venturi profile, such that the reservoir fluid comprises the free gas phase and a liquid phase;
(b) a diffusion profile disposed above the throat of the Venturi profile and having a transverse cross-sectional area that gradually increases in the axial uphole direction, the diffusion profile configured to condense the free gas phase into the liquid phase as the reservoir fluid flows in the axial uphole direction through the diffusion profile; and
(c) an inlet port section defining a plurality of inlet ports, each having an axis aligned with the axial uphole direction,
wherein the plurality of inlet ports comprises at least one central inlet port and a plurality of spaced apart peripheral inlet ports.
