Abstract

Two production springs extend downwardly from a well head of an oil well to a point adjacent a producing region. Lower ends of the two production strings are connected by a coupling which allows a mechanical interface launched adjacent the well head of one of the production strings to descend along the production string through the coupling and upwardly through the other production string to displace oil from the production strings to a surge tank. High pressure gas is utilized to move the mechanical interface through the production strings and suitable valves are provided for controlling the flow of gas and oil through the production strings.
