Abstract: A multi-tooth jaw for a torque stopper device prevents rotation of downhole tools suspended in a wellbore casing. The jaw includes a base for positioning adjacent an outside wall of the torque stopper and a hinge connection allowing the jaw to pivot around an axis of rotation running lengthwise through the base. The jaw further includes a plurality of radial tips, i.e., teeth, each a different distance from the axis of rotation. When viewed from a side with the axis of rotation being a point around which the jaw pivots, the tips are in ascending order of distance with a first, leading tip having a shortest distance from the axis of rotation as the jaw pivots from a stowed to a deployed position. A torque stopper device with the multi-tooth jaw supports a range of casing internal diameters. A repair kit allows swapping a one-tooth jaw with the multi-tooth jaw.

Abstract: A tubing anchor catcher for anchoring well equipment in a well conduit to arrest movement in both longitudinal directions and rotational directions. A mandrel connected to the equipment has one or more grooves for slideably receiving respective drive pins from a drag body on the mandrel. A slip cage on the mandrel houses a slip or slips for selectively engaging and disengaging the conduit. Manipulation of the mandrel at surface causes the drive pins to move within the one or more grooves on the mandrel and the drag body conical surface to move toward the slip cage driving the slip or slips outward to grip the conduit. Further pulling at surface maintains the set position. The anchor is unset at surface by releasing the tension, rotating the mandrel in the second direction, and pulling the mandrel to disengage the slip or slips.

Abstract: The present invention provides a ¼ turn tubing anchor catcher for use in tubing strings within petroleum wells. The tubing string may also include a pump for increasing the delivery of petroleum through the well bore. The ¼ turn tubing anchor catcher can be set by a quarter turn. The ¼ turn tubing anchor catcher may act as an anchor that prevents rotation caused by the pump. The ¼ turn tubing anchor may also act as a catcher if the structural integrity of one or more portions of the tubing string fails. The present invention also provides an anchoring and movement reducing system that comprises a ¼ turn tubing anchor catcher, a pump and an torque anchor section. The system anchors the tubing string against rotation caused by the pump. The system may also act as a catcher if the structural integrity of one or more portions of the tubing string fails.

Abstract: A torque anchor for anchoring well equipment in a well conduit to arrest movement in both longitudinal directions and rotation in a first direction, but not rotation in an opposed second direction. A mandrel connected to the equipment has one or more grooves for slideably receiving respective pins from a drag body on the mandrel. A slip cage on the mandrel houses slips for selectively engaging and disengaging the conduit. Manipulation of the mandrel at surface causes the pins to move within the one or more grooves on the mandrel and the drag body to move toward the slip retainer driving the slips outward to grip the conduit. Further pulling at surface maintains the set position. The anchor is unseta surface by releasing the pull, rotating the mandrel in the second direction, and pushing the mandrel to disengage the slips.

Abstract: A tubing anchor for anchoring and catching well equipment in a well conduit to arrest movement in both longitudinal directions and rotation in a first direction. A mandrel connected to the equipment has in one embodiment C or reverse C-shaped grooves when viewed in front elevation for slideably receiving respective pins from a drag body on the mandrel. A slip retainer on the mandrel houses slips for selectively engaging and disengaging the conduit. An initial pull of the mandrel causes the pins to move the drag body toward the slip retainer driving the slips outward to grip the conduit. Rotation of the mandrel in the first direction sets the anchor to arrest movement. Further pulling and a reversed turn of the mandrel maintains the set position. A spring biases the slips outward to maintain their set to catch the well equipment in the event of a break in the string above the anchor.

Abstract: A torque anchor for anchoring well equipment in a well conduit to arrest movement in both longitudinal directions and rotation in a first direction, but not rotation in an opposed second direction. A mandrel connected to the equipment has L-shaped grooves for slideably receiving respective pins from a drag body on the mandrel. A slip retainer on the mandrel houses slips for selectively engaging and disengaging the conduit. An initial pull of the mandrel causes the pins to move the drag body toward the slip retainer driving the slips outward to grip the conduit, and rotation of the mandrel in the first direction sets the anchor to arrest movement. Further pulling maintains the set position. The anchor is unset by releasing pull, rotating the mandrel in the second direction, and pushing the mandrel to disengage the slips. Alternate unsetting requires increased pull beyond the shear resistance of the slip retainer.

Abstract: A torque anchor for use with progressive cavity pumps (PC Pumps) for preventing rotation of the PC Pumps and any related tool string within a well bore, possessing a connector constructed and adapted to connect a tube, which in a preferred embodiment is a diluent cable, between the two fixed slips. A method is also recited for running coiled tubing or a diluent cable downhole using the torque anchor.

Abstract: The invention describes a torque anchor for use with progressive cavity pumps (PC Pumps) for preventing rotation of the PC Pumps and any related tool string and tubing within a wellbore. The torque anchor includes at least one fixed rigid slip and one pivotable slip that in combination enhance the ability of the torque anchor to remain centered within wellbore casing and provide space between the torque anchor and wellbore casing for other tubing and/or other cabling or instruments to be run within the well and/or facilitate the passage of sand and other substances indigenous to many well formations past the torque anchor.

Abstract: An apparatus for remotely cleaning an overhead gutter (10) includes a first and a second fork (17, 25) disposed near the top of an elongated handle (15). The first fork (17) is stationary with respect to the handle (15) and is slid along the interior of the gutter. The second fork (25) is adapted for rotational motion with respect to the first fork (17) in order to selectively engage debris positioned therebetween. The gutter cleaner also includes a pusher blade (47) mounted on the second fork (25) for cleaning under gutter hanger spikes (10e), as well as brush (74) and mirror (78) attachments.
