| 71 | Logging tool retrieval system | US19663 | 1998-02-06 | US5984009A | 1999-11-16 | Rocco DiFoggio |
| An apparatus as method for identifying, locating, and retrieving a downhole tool from a borehole. A controller is lowered into the borehole and is capable of detecting a signal from the tool. The signal can be broadcast from the tool, can be generated in response to a signal from the controller, or can be reflected from a controller signal. The controller processes the signal to identify the location and heading of the controller from the tool, and to guide the controller toward the tool. When the controller is moved proximate to the tool, a catch mechanism can be activated to connect the tool and controller housing. The tool is then dislodged for further operation, or is retrieved to the borehole surface. | ||||||

| 73 | Whipstock apparatus and methods of use | US201800 | 1994-02-25 | US5425419A | 1995-06-20 | Bobby G. Sieber |
| An oil field Whip-Anchor System, for deviating a well bore, which uses an improved Whipstock incorporating a new setting apparatus and method, attached to a hydraulic or mechanical anchor packer is disclosed. The complete Whip-Anchor System also includes an apparatus and method for retrieving the Whip-Anchor if it is used in well bores which require retrievable well bore deviation tools. The new apparatus reduces the number of whipstock bodies that must be warehoused to three fundamental types which fit all commonly used well bores. The apparatus permits the proper "set" of a mechanical packer without fear of shearing the releasable attachment device currently used in the industry and permits an operator to "bottom hole wash" while setting a mechanical packer in a well bore. The same technique and apparatus are used for both mechanical or hydraulic packers. The system utilizes a slot cut in the face of the whipstock for setting and retrieval. Other improvements include a pinned spring loaded hinge assembly which assures that the tip of the whipstock will fall against the well bore, a deflector plate that uses polycrystaline diamond inserts to reduce wear on the top portion of the device during the window milling operation. | ||||||
| 74 | Downhole oil and gas well jacking tool for use with coil tubing unit | US160898 | 1993-12-02 | US5370180A | 1994-12-06 | Phil Barbee |
| A coil tubing supported jacking tool can be used to remove articles that are stuck in an oil and gas well casing bore. The coil tubing unit transmits pressurized fluid to the tool body. At its lower end, the tool body grips the stuck article. A piston chamber expands to set slips for anchoring the tool body to the well casing. The piston then moves upwardly away from the slips, pulling the stuck article free. | ||||||
| 75 | Wireline hydraulic retrieving tool | US749176 | 1991-08-23 | US5228507A | 1993-07-20 | Marcel Obrejanu; David H. Weiler |
| In wireline operations, it is known to retrieve objects stuck in a well bore by application of a retrieving force applied to the object through the wireline and a wireline pulling tool attached to the wireline and engaged with the object. The present invention provides a wireline retrieving tool which is adapted to apply a large retrieving force on a pulling tool engaged with an object in the well bore without having that force transmitted directly through the wireline. The retrieving tool is adapted to be lowered into the well bore on the wireline to a position where the pulling tool engages the stuck object. Slips carried on in the tool then anchor the tool against the tubular casing or tubing of the well bore and a controlled retrieving force generated in the tool by an electric motor and hydraulic pump is applied between the casing or tubing and the pulling tool to dislodge the object. | ||||||
| 76 | Downhole force generator | US574815 | 1990-08-30 | US5070941A | 1991-12-10 | Marion D. Kilgore |
| A hydraulic well tool for running into a flow conduit of a well on a handling string, such as reeled tubing or jointed pipe, for generating and applying an axial force to an object in the well, the well tool including an anchoring mechanism actuatable by fluid pressure in the handling string for anchoring the well tool in the flow conduit, this well tool further including a piston/cylinder arrangement also actuatable by fluid pressure in the flow conduit for moving the aforementioned object. The object may be a well tool, a sliding sleeve, a fish, or other well tool. The hydraulic well tool may be provided with a suitable device to permit increasing the pressure in the handling string for actuation of the anchoring mechanism and the piston/cylinder arrangement. Devices suitable for such purpose include a flow restrictor, ball and seat, velocity check valves, plugs, or the like devices. The displacement of such object is brought about hydraulically while the well tool is anchored in the flow conduit and without axially stressing the handling string. The anchoring mechanism includes piston type anchor members each formed with a sinusoidal seal ring recess at its inner end for increasing the stroke of the anchor members, and with a recess running across the inner face of the anchor member in a direction parallel to the longitudinal axis of the well tool to avoid obstructing the longitudinal body bore. | ||||||
| 77 | Fishing tool to retrieve cables from wells | US193304 | 1980-10-02 | US4353585A | 1982-10-12 | Herman C. Carver |
| A fishing tool to snag and to retrieve cables from wells. The tool includes an elongated body which has two ends, a substantial length, and peripheral boundary of lesser lateral dimensions than a well down which the tool is to be sent with the first of its ends pointed down. A snag member comprises a shank and a snag end on the shank. The shank is mounted to the body so that the snag end faces toward the second of said ends and so that the snag end is movable toward and away from the peripheral boundary. Bias means biases the shank to move the snag end toward the peripheral boundary, and a detent is interposed between the snag member and the body releasably to hold the snag member with its snag end away from the boundary in opposition to the bias force, where it can be released upon contact with an object. | ||||||
