Abstract: A subterranean debris catcher swirls the incoming debris laden stream by putting grooves or spiral projections on the inside of the inlet pipe. The solids come out of openings in the side of the inlet pipe or the solids can exit near the top either directly into the enclosed solids holding volume as the liquid exits straight out or the solids can be discharged out the end of the inlet pipe into the bigger open space defined by the housing. In the latter case the inside housing wall can have a screen or vanes that slow down the solid particles as the fluid continues to a housing exit and eventually to an exit screen before being discharged to either go to the surface or recirculate back along the outside of the tool to the inlet pipe while picking up additional debris.

Abstract: A mill cutting structure is differently configured in three zones. Those zones are the center, the outer edge and in between. At the center has highly wear resistant material that has good temperature bond strength and high impact resistance. The outer periphery can have a material that is highly resistant to wear and impact. In between can be inserts such as used in the Metal Muncher® mills using sintered carbide shapes that resist tracking and create a chipping rather than a grinding action. The shapes should have high edge retention capability and shapes such as a double sided pyramid can be used. The wear patterns of prior designs are addressed to allow longer and faster milling of the fish.

Abstract: A subterranean debris catcher swirls the incoming debris laden stream by putting grooves or spiral projections on the inside of the inlet pipe. In some embodiments the solids come out of openings in the side of the inlet pipe and in others the solids can exit near the top either directly into the enclosed solids holding volume as the liquid exits straight out or the solids can be discharged out the end of the inlet pipe into the bigger open space defined by the housing. In the latter case the inside housing wall can have a screen or vanes that slow down the solid particles as the fluid continues to a housing exit and eventually to an exit screen before being discharged to either go to the surface or recirculate back along the outside of the tool to the inlet pipe while picking up additional debris.

Abstract: A grapple device is secured to a mill to allow relative rotation between them. The grapple has an outward bias to allow it to grip the packer bore or an extension from the packer. The mandrel has a wedge adjacent its lower end and torque fingers that fit between grapple segments when relative longitudinal movement occurs between the mandrel and the grapple assembly. The grapple assembly has a left hand thread so that it comes out of the packer if the mandrel engages the grapple assembly in a manner for tandem rotation. The torque fingers on the wedge on the mandrel support the grapple fingers over their length as rotation to the right removes the grapple assembly from the packer bore. Reverse circulation takes away the cuttings into the mill bore where they are separated from the reverse circulating fluid.

Abstract: A debris removal tool has a lower end pickup hose into which debris laden fluid is pulled when there is circulation through the debris removal tool from the surface. An anchor near the open end of the hose stabilizes the lower end near a recess or groove from which debris is to be removed. Once the anchor is set the hose can be extended or retracted as well as rotated on its axis to pick up debris. A camera can be located in or near the hose opening to be able to see where the debris is located and for confirmation that the debris is being removed and that the debris has fully been removed.

The second plurality of cutting elements are substantially identical in shape to each other, and the second plurality of cutting elements are interspersed with the first plurality of cutting elements at the cutting end of the tool body. Also included is a method for making a cutting/milling tool.

Abstract: A debris removal device features structural support from an exterior housing that allows more space for debris collection. The debris enters the collection volume from the top to eliminate debris from having to go through a valve. The screen in the device is disposed internally to protect it during handling and running. A variety of external flow diverters are used to direct debris laden fluid into the tool and to keep debris out of an annular space around the tool that could interfere with its removal. The diverters can be actuated by relative movement in the tool or applied pressure to a piston which can inflate a sleeve or orient or misalign paths through brushes for selective bypassing of fluid exterior to the tool.

Abstract: A subterranean screen system features openings in a base pipe and sleeve sections of a porous material that preferably swells in the borehole to span an annular space around the base pipe. Retainers are mounted to the base pipe in a desired location and mechanically fixated using an internal grip system actuated through the wall of the retainer. A wedging action of slip segments is initiated by an angularly advancing assembly through the wall of the retainer. The retainer can have end rings extending past one or both ends over which the screen sleeve extends. Flat or ridges on the exterior of the retainer or end rings make assembly easier with hand tools to allow for rapid field assembly, if needed. Filtration occurs through the sleeves that abut the borehole wall and into the base pipe openings and to the surface.

Abstract: Cutting elements for cutting tools comprise a pre-formed fracture plane disposed in at least one surface of the cutting elements. The pre-formed fracture plane can comprise a groove cut into one of the surfaces of the cutting element, or the pre-formed fracture plane can be formed by using a laser or other heat concentrating source to weaken a portion of one of the surfaces of the cutting element so that the cutting element will break along the pre-formed fracture plane.
