Abstract: A method of deliquification of production wells includes placing an artificial lift tool in a gas wellbore, where the artificial lift tool includes a rack and multiple piezoelectric transducers. The rack includes multiple trays. Each piezoelectric transducer of the multiple piezoelectric transducers is positioned on a respective tray of the multiple trays. The method further includes providing, by a pump, a liquid on surfaces of the multiple piezoelectric transducers and providing, by a signal source, an electrical signal to the multiple piezoelectric transducers. The method also includes generating, by the multiple piezoelectric transducers, acoustic waves from the electrical signal, where at least some of the liquid provided to the multiple piezoelectric transducers is atomized by the acoustic waves.
