Abstract: A tool, such as a tape measure, including a spring-based retraction system is shown. Various spring-based retraction system embodiments are configured to decrease the size occupied by the spring within the tape measure housing, which consequently reduces tape measure housing size providing a more compact tape measure. Various spring-based retraction system embodiments are configured to control retraction of the tape measure in a manner that reduces whip or otherwise controls tape blade retraction. Some retraction system embodiments utilize a reduction gear train, and others utilize a compression spring and a transmission system that converts rotational movement of the tape reel to axial movement, which compresses the spring.

Abstract: A one trip bottom hole assembly allows setting and testing a plug and release from the plug. Cement can be pumped onto the plug, after the BHA is raised, to an extent to meet local regulatory requirements. The cutter spear combination can be activated with pressure built on a second dropped ball larger than the first ball to release the blades for extension with fluid circulation. The circulation path through the spear is opened using pipe manipulation during the spear setting sequence. The cuttings from severing the tubular fall onto the cement. The spear is set with string manipulation as the drill string rotates the blades while maintaining the string under tension. The spear can be released and repositioned for the top of the string to facilitate removal and disassembly at the surface. All the above described operations are accomplished with a single trip into the hole.

Abstract: A combination tool is delivered to compacted debris above a packer whose plug is to be removed. The shoe or mill is on the lower end of an outer bushing and the grapple or overshot is held within the bushing but away from the shoe so that the shoe can advance into the debris as reverse circulation takes the cuttings up through a mandrel to a debris removal tool. When the shoe lands on the packer the surface personnel can see it on the weight indicator. Weight is then set down to overcome a resisting force of a breakable member such as a shear pin or a spring or both so that the grapple advances to engage the packer plug. Advancing the mandrel relative to the bushing with the shoe at its lower end also releases a torque lug that previously allowed tandem rotation of the mandrel with the bushing.

Abstract: Magnetic retrieval tools for use in a wellbore or other tubular member to remove metallic debris. A magnetic retrieval tool includes a tool body having a central shaft with a plurality of ribs that project radially outwardly therefrom. The ribs present lateral sides that have recesses formed therein. Magnet bars are retained within the recesses by wedge members and retaining rings. The magnet bars include a hollow protective housing that encloses a plurality of magnets. Retaining plugs are used to secure the magnets within the housing.

Abstract: A magnetic retrieval tool used for collecting metallic debris and material from within a wellbore or other surrounding downhole tubular. The tool includes a tool mandrel. A removable insert resides upon the tool mandrel. The insert retains a plurality of individual magnets in a fixed array or matrix surrounding the mandrel.

Abstract: A magnetic retrieval tool used for collecting metallic debris and material from within a wellbore or other surrounding downhole tubular. The tool includes a tool mandrel with one or more pockets formed in its outer radial surface. A removable insert resides within each pocket. Each of the inserts retains a plurality of individual magnets in a fixed array or matrix surrounding the mandrel.

Abstract: A ball catcher is designed to stop balls that are the same size or different sizes at an inlet on a seat that is connected to a movable biased sleeve. Once the ball or other shaped object lands at the seat the flow around it increases differential pressure on the seat and sleeve and displaces them against the bias. The ball goes into a surrounding annular space and cannot exit. A preferably spiral sleeve guide the movement of the balls in the annular space so that efficient use of the annular space is made to maximize the number of balls that can be captured per unit length of the annular space. As soon as the ball enters the annular space the sleeve shifts back to the original position to stop the next ball at the inlet. Once in the annular space, the balls cannot escape if there is a flow reversal. The central passage remains open to pass other tools and flow.

Abstract: A magnetic retrieval tool used for collecting metallic debris and material from within a wellbore or other surrounding downhole tubular. The tool includes a tool mandrel with a removable insert which contains one or more magnets. The insert is formed such that both the north and south magnetic poles of the one or more magnets are able to attract metallic debris.
