System, apparatus and method for well deliquification

摘要

A system or apparatus 10 for deliquification of production wells and a method thereof. The system or apparatus may comprise a production tube 22 that receives produced fluid from a subterranean reservoir 14 and provides a pathway 12 for transmission of the produced fluid to a surface location 16. The production tube includes at least one nozzle 40 disposed therewithin and an opening 82 positioned proximate to the nozzle through which a foaming agent is introduced into the production tube via an injection line 80. The nozzle has a first end 42 that defines an inlet 48, a second end 44 distal to the first end that defines an outlet 50, and a passageway 46 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.
