Zusammenfassung:	A method, related device and system are provided for lifting a reservoir fluid in an oil and gas well. The method involves allowing the reservoir fluid to flow in an axial uphole direction through an internal flow path of a production tubing disposed in the well. The internal flow path includes a 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. The internal flow path also includes a diffusion profile disposed above the Venturi profile and configured to condense the free gas phase into the liquid phase as the reservoir fluid flows in axial uphole direction through the diffusion profile.
