Abstract

Embodiments of an apparatus, a system, and a method are provided for deliquification of a production well. The apparatus can be a production tube that receives produced fluid from a subterranean reservoir and provides a pathway for transmission of the produced fluid to a surface location. The production tube includes a nozzle disposed therewithin and an opening positioned proximate to the nozzle through which a foaming agent is introduced into the production tube. The nozzle has a first end that defines an inlet, a second end distal to the first end that defines an outlet, and a passageway extending between the first end and the second end such that the produced fluid received by the inlet is delivered to the outlet. The passageway defines a region of decreased cross-sectional area that agitates the produced fluid passing through the nozzle thereby increasing mixing of the foaming agent.
