Abstract: Overshot fishing tools for retrieving objects, i.e., “fish” lodged within a wellbore are disclosed. The overshot fishing tool comprises a housing having a housing bore with at least one recess disposed along the inner wall surface of the housing bore. A slip is disposed within each of the recesses. Each slip has a gripping profile for engaging and securing the fish. Each slip also has a length and a width such that the slip, when actuated, provides circumferential loading on the housing. In specific embodiments, each slip includes two or more different gripping profiles to facilitate retrieval of different types and sizes of fish.

Abstract: A downhole tool for engaging a borehole wall of a well, with outwardly displacing gripping elements to engage the borehole wall in such a way as to prevent rotation of the tool relative to the borehole wall, thereby preventing a downhole motor from imposing a reactive torque on the workstring uphole from the tool. The gripping elements can have one or more rolling elements, such as wheels, to roll longitudinally along the borehole wall in either the uphole or downhole direction, or both, while preventing transmission of reactive torque to the workstring. The gripping elements can also be configured to prevent longitudinal motion of the tool, such as blades. Displacement of the gripping elements can be hydraulically actuated.

Abstract: A blade support assembly for use with a casing cutter to cut through casing or pipe downhole in a well. A tubular body fits over the casing cutter, with slots aligned with the pivoting cutter blades. Support plates next to each slot provide support for the blades during cutting operations. Torque keys and matching torque slots in the blade support assembly and the casing cutter body transfer torque from the casing cutter body to the blade support assembly, and thence to the blades.

Abstract: A stabilizer (36) mounted on a mandrel (14) of a workstring (12) within a casing (10) of a well bore hole. The stabilizer (36) has an upper carrier (38) fixed to the mandrel (14) and a lower carrier (40) mounted on the mandrel (14) for relative sliding movement. Shoes (70) are mounted by links or arms (64, 74) to bearing housing (50, 80) on the carriers (38, 40). The bearing housings (50, 80) are mounted for relative rotation on the carriers (38, 40) and permit the mandrel (14) and workstring (12) to rotate relative to the shoes (70) upon fluid actuation of lower carrier (40) and engagement of the casing (10) by the shoes (70).

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: 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.
