Abstract:

A mechanically actuated tubing drain for service with oil wells, water wells, gas wells and/or thermal wells has a configuration in which the drain opens by operation of a bumper member which may be pulled upwardly to move a sleeve member which is initially positioned adjacent to a drain port, thereby sealing the drain port. Once the bumper member pushes the sleeve member upwardly, any fluid in the tubing above the drain port will drain from the tubing. The bumper member may be pulled upwardly either by upward movement of a rod string or by operation of a wireline or slickline tool. The mechanically actuated drain does not require a tubing anchor to operate.
