A slickline shredder tool includes a housing, a housing inlet, a power receiver, a shredder coupled to the power receiver, and a storage unit. The shredder rotates about a first axis when the power receiver receives power. Malfunctioning slickline enters the housing through the housing inlet and is shredded into shredded pieces by the shredder. The shredded pieces are stored in the storage unit.

Systems and methods for retrieving equipment from a wellbore of a subterranean well include an overshot housing having a central axis. The overshot housing is a tubular shaped member with a housing bore. An internal sleeve is located within the overshot housing. The internal sleeve is a tubular shaped member with a sleeve bore. The internal sleeve is axially moveable within the overshot housing. A catching net is located radially outward of the internal sleeve, within the overshot housing. The catching net moveable between a contracted position and an extended position. The catching net has a shorter axial length and a wider radial width in the contracted position than in the extended position. An anchoring assembly is located at a downhole end of the catching net. The anchoring assembly is actuable to releasably secure the downhole end of the catching net to the equipment.

A wireline recovery tool for retrieving a wireline from a wellbore includes an outer sheath and a rotatable spear positioned within the outer sheath. The rotatable spear includes a plurality of angled portions and a plurality of vertical portions such that the rotatable spear has an asymmetrical profile. The outer sheath includes a first and second wall, each of which includes an inner surface and an outer surface. A plurality of angled prongs extend from the inner surfaces of the first and second walls. A torque device including an indexing mechanism and ratcheting mechanism rotates the rotational spear positioned within the outer sheath. As the rotatable spears rotates, the wireline being retrieved from the wellbore becomes increasingly entangled with the rotatable spear and outer sheath, such that the wireline can be removed from the wellbore.

The present disclosure describes a cable head for a wireline tool that includes a housing that comprises an outlet opening for a wireline and an interface configured to connect the housing to the wireline tool; a spool rotatably mounted in the housing; an anchoring point configured for mechanical attachment to an end of the wireline; and a drive configured to rotate the spool and thereby wrap a portion of the wireline around the spool to and retract the wireline into the housing. A wireline tool and a method of retrieving a lost wireline tool are also described.

The present disclosure is directed to a fishing head and a steel boot of a downhole receiver tool. In certain embodiments, the fishing head may include multiple body portions that include a channel to hold a cable of a downhole tool and a recess that is formed at the interface of the body portions. The body portions may be coupled via one or more pins that are fitted into the recess. In certain embodiments, a collar may be positioned on an exterior portion of the body portions of the fishing head to further secure the components. In certain embodiments, the collar may be coupled to the body portions of the fishing head via a biasing member such as a spring pin or other suitable coupling components.

A wireline fishing tool includes a body having opposing upper and lower ends and defining an inner flowpath extending between the upper and lower ends, a spear arranged within the inner flowpath and including a spear body having opposing uphole and downhole ends and an inner channel extending between the uphole and downhole ends. One or more hooks are pivotably attached to the spear body at the downhole end, wherein the spear is movable between a retracted state, where the one or more hooks are arranged within the inner flowpath, and an extended state, where the spear body extends out of the inner flowpath at the lower end and the one or more hooks exiting the inner flowpath, and the one or more hooks pivot radially outward and away from the spear body upon exiting the inner flowpath.

A cable grab assembly includes a body having a longitudinally extending internal cavity disposed therein. A piston is disposed in the cavity and is axially moveable between a first position and a second position. At least two grab arms are hingedly attached to a bottom end of the body. A linkage assembly operatively couples the piston and the at least two grab arms such that movement of the piston between the first position toward the second position causes the at least two grab arms to pivot inward from an open position toward a closed position. A shear-pin restrains the piston to the first position. At least one spring element is disposed between the piston and an end of the cavity to shift the piston from the first position toward the second position to capture a broken cable when the shear-pin is sheared.

A coiled tubing venturi junk basket tool retrieves junk, debris and/or wireline from a wellbore. A collection housing or waste basket is removeably coupled to the venturi body. The collection housing (waste basket) is customizable for volume, hole diameter and the type of junk and debris retrieved. An elastomeric trap is used to retain junk and debris in the collection housing. The collection housing is also interchangeable with a grab housing for retrieving wireline.

A slickline shredder tool includes a housing, a housing inlet, a power receiver, a shredder coupled to the power receiver, and a storage unit. The shredder rotates about a first axis when the power receiver receives power. Malfunctioning slickline enters the housing through the housing inlet and is shredded into shredded pieces by the shredder. The shredded pieces are stored in the storage unit.
