Claim:
1. A method for artificial lift deliquification of production wells, the method comprising: (a) providing a wellbore that receives reservoir fluids from a producing zone of a subterranean reservoir, the reservoir fluids comprising gas and liquid, wherein the liquid comprise hydrocarbon, water and mixtures thereof in a liquid column at the bottom of the wellbore; (b) providing a production tubing or a casing in the wellbore, wherein the production tubing or casing has a plurality of perforations for gas to flow from the reservoir up the production tubing or casing for subsequent recovery; (c) providing a downhole tool down the production tubing or casing in the wellbore, the downhole tool comprising: (d) generating the acoustic wave with the atomizing chamber, wherein the acoustic wave generated by the atomizing chamber has a frequency in an ultrasonic spectrum; (e) vaporizing the liquid within the atomizing chamber through vibration of the liquid by the acoustic wave emitted within the atomizing chamber, wherein vaporizing the liquid converts that liquid into the droplets; and (f) transporting the droplets that exit the atomizing chamber to a well surface by the gas flow up the production tubing or casing.
