Abstract
A system, apparatus and method are useful for lifting reservoir fluid in a gas-producing wellbore through the application of a differential between pressure of the gas in the wellbore's gas-production conduit a lower end of which is disposed in reservoir fluid accumulated at a bottom of the wellbore and pressure of the wellbore annulus. The apparatus comprises a collection module disposed in the gas-producing wellbore for collecting by condensation reservoir fluid being lifted as vapor with produced gas in a gas-production conduit disposed in the wellbore, and one or more lift modules for applying the pressure differential to lift the reservoir fluid collected by condensation, and optionally reservoir fluid accumulated at the bottom of the wellbore, within the wellbore.
