摘要： A casing spear may comprise a mandrel, and a slip assembly comprising at least one slip. The at least one slip may comprise a generally wedge-shaped surface positioned and configured to cause the at least one slip to move radially outwards relative to the mandrel in response to a rotation of the mandrel and a torque acting on the slip assembly, the torque opposing the rotation of the mandrel. Additionally, a method of operating a casing spear may comprise inserting a casing spear into a casing, rotating a mandrel of the casing spear, applying a torque to a slip assembly of the casing spear with the casing, opposing the rotation of the mandrel, and applying a force in a radial direction to at least one slip of a slip assembly of the casing spear in response to the torque.

摘要： A wellbore cleanup tool collects debris when moved in one direction downhole. A flow diverter is extended for such flow diversion when debris is collected. When running the tool in the opposite direction in the wellbore, the flow diverter is in whole or in part articulated to retract so as to reduce resistance to fluid that passes around the outside of the tool. A segmented diverter can have fixed and movable components that are guided. The movable components can become longitudinally offset from the fixed components for movement in the direction where maximum flow bypass around the outside of the tool is desired. In an alternative embodiment, the diverter segments can all be movable on an inclined track to retract against a bias force for fluid bias with movement of the tool in the opposite direction allowing the bias to push the segments on the inclined track for diversion of debris laden fluid into a capture volume in the tool.

摘要： 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.
