ABSTRACT:
A chamber in a well is connected to two externally separate tubing strings to unload liquid which is applying backpressure against a formation so that the production of fluid from the formation is obstructed. Volumes of the liquid are intermittently collected in the chamber and lifted out of the well through one of the tubing strings in response to high pressure gas injected solely into the chamber through the other tubing string.
