Abstract
A method for producing fluid from a well includes inserting a pump into a well tubing having at least one gas lift valve disposed at a selected depth. The pump arranged to lift fluid below the pump into the well tubing. A gas pressure in an annular space between the well tubing and a well casing is increased until the gas reaches a flow port in the tubing proximate the pump. The pump is operated by continuing pumping gas so as to lift fluid from a subsurface reservoir to the selected depth of the at least one gas lift valve.
