Abstract: Embodiments for deliquification of produced fluid being produced from a well are provided. In one embodiment, a system comprises a production tubing, a casing, or both that receive the produced fluid from a subterranean reservoir and provide a pathway for transmission of the produced fluid to a surface location. The system also comprises a nozzle disposed within the production tubing, the casing, or both. The nozzle includes a passageway extending between an intake and a diffuser such that the produced fluid received by the intake flows through the nozzle via the passageway. The passageway includes a region of decreased cross-sectional area at a throat that reduces the pressure of the produced fluid passing through the nozzle and the produced fluid is deliquefied as it flows through the passageway. The system also comprises a sealer, a stopper, or both coupled to the nozzle to form a nozzle assembly.
