Embodiment Construction

[0012]The present invention provides an improved tool and method for retrieving actuator balls and engaging and shifting elements of the valves. The present invention's particular applicability is to multiple sleeve wellbores that are actuated by balls of the same diameter.

[0013]Referring more particularly to the drawings, wherein like reference characters are used throughout the various figures to refer to like or corresponding parts, there is shown in FIG. 1 one embodiment of the tool 10 of the present invention which is adapted to be lowered into a wellbore while connected to a wire line or tubular string. It should be understood by those skilled in the art that the use of directional terms, such as above, below, upper, lower, upward, downward and the like are used in relation to the illustrative embodiments as they are depicted in the figures, the upward direction being toward the left side of the corresponding figures and the down-hole direction being toward the right side of t...

Abstract

Disclosed is a tool for changing a plurality of sleeve valves in a well from a ball catching restricted bored state to an open bore state and for retrieving sleeve valve actuator balls of substantially the same diameter from the well.

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...
