Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] None.BACKGROUND

[0002] 1. Technical Field

[0003] This invention relates to tools for recovering actuator elements, such as, balls and darts, inserted into wells from the surface to actuate subterranean well tools such as sliding sleeve valves and tools for shifting the well tools. More particularly, this invention relates to recovering actuator elements from sleeve valves and for shifting elements of the valves.

[0004] 2. Background Art

[0005] It is common to assemble and install wellbores with a plurality of sleeve valves spaced along the length of the wellbore to provide access to selected formation areas along the wellbore. These sleeve valves are operated by inserting and pumping actuator elements down the wellbore. These balls engage a seat on the valve's sleeve allowing pressure to build up to force the ball and sleeve to shift to the open position. It is also common to use circular cross section shaped actuator darts instead of spherical b...
