| 121 | Tools and methods for hanging and/or expanding liner strings | US12436073 | 2009-05-05 | US08286717B2 | 2012-10-16 | Richard L. Giroux; Michael Lynch; Lev Ring |
| Embodiments of the invention generally relate to tools and methods for hanging and/or expanding liner strings. In one embodiment, a method of hanging a liner assembly from a previously installed tubular in a wellbore includes running the liner assembly and a setting tool into the wellbore using a run-in string. The setting tool includes an isolation valve and the liner assembly includes a liner hanger and a liner string. The method further includes sending an instruction signal from the surface to the isolation valve, wherein the isolation valve closes in response to the instruction signal and isolates a setting pressure in the setting tool from the liner string; and increasing fluid pressure in the setting tool, thereby setting the liner hanger. | ||||||

| A rope socket comprises a slip cone subassembly having a straight outer diameter and a tapered inner diameter. A plurality of slips is positioned within the slip cone body. A retainer ring holds the slips together. A guide plug is positioned within the slips to maintain the slips in an opening position during insertion of a cable. A spring stabilizer having a spring thereon is coupled above the slip cone assembly to ensure even compression of the spring. A safety slot is located on the body of the rope socket in order to provide a visual indication of the cable position. | ||||||
| 123 | OVERSHOT DEVICE | US13379233 | 2010-06-10 | US20120125612A1 | 2012-05-24 | Patrick Salvador |
| A device with an overshot including a first part with an elongated body adapted to be connected to a hoisting line in one end and with a tubular opening arranged/designed to receive a spearhead in the other end. The overshot further includes a second part with a scissor like mechanism including two lifting dogs arranged to pivot around a common pivot pin. The lifting dogs are connected via a biasing unit and the elongated body includes a central, axially extending slot. The scissor like mechanism is arranged with the common pivot pin sliding in the slot between a first end position where the biasing unit is arranged to close the lifting dogs such that a spearhead received in the tubular opening is locked and a second end position where an opener including an opening pin is arranged to force the lifting dogs open against the force of the biasing unit, such that a spearhead received in the tubular opening is released. | ||||||

| 125 | SIGNAL OPERATED TOOLS FOR MILLING, DRILLING, AND/OR FISHING OPERATIONS | US12436077 | 2009-05-05 | US20090266544A1 | 2009-10-29 | Thomas M. Redlinger; Thomas Koithan; Christopher M. Vreeland; Wesley Don Heiskell; Andrew Antoine; Scott McIntire |
| Embodiments of the present invention generally relate to signal operated tools for milling, drilling, and/or fishing operations. In one embodiment, a mud motor for use in a wellbore includes: a stator; a rotor, the stator and rotor operable to rotate the rotor in response to fluid pumped between the rotor and the stator; and a lock. The lock is operable to: rotationally couple the rotor to the stator in a locked position, receive an instruction signal from the surface, release the rotor in an unlocked position, and actuate from the locked position to the unlocked position in response to receiving the instruction signal. | ||||||
| 126 | Combined washover and retrieval device | US587465 | 1996-01-17 | US5810410A | 1998-09-22 | Roy S. Arterbury; Thomas C. Burroughs |
| A combined washover and retrieval device (30, 30A) for connection to the lower end of a tubular string (14, 14A) including an outer washover pipe (22, 22A) and an inner retrieval tool (36, 36A). Retrieval tool (36, 36A) includes an upper sub (30, 30A) secured at its upper end to a tubular support (23, 23A). In a preferred embodiment of FIG. 1-3, the sub (30) has a plurality of ports (35) to permit the upward flow of fluid with entrained soil and debris through the inner annulus (38) and ports (35) at the upper end of the annulus (38) to bypass the retrieval tool (36). Another embodiment illustrated in FIGS. 4-7 has a plurality of shear pins (31A) connecting the washover pipe (22A) to the sub (30A). Pins (31A) are sheared upon washover pipe (22A) abutting the packer (16A) under a predetermined weight from the tubing string (14A) to permit downward relative movement of retrieval tool (36A) for connection to the fish (18A). | ||||||
| 127 | Method for retreiving a slotted face wellbore deviation assembly using a retrieval tool | US420344 | 1995-04-11 | US5474133A | 1995-12-12 | Bobby G. Sieber |
| A method for retrieving a specially designed and retrievable slotted face wellbore deviation apparatus incorporating a special whipstock attached to a hydraulic or mechanical anchor packer is disclosed. The method utilizes a hook shaped retrieval tool which is guided along a slot cut in the face of the whipstock portion of the deviation apparatus and engages within a retrieving slot set in the face of the whipstock. | ||||||
| 128 | Rectilinear tool for use with a slotted face wellbore deviation assembly | US419915 | 1995-04-11 | US5467821A | 1995-11-21 | Bobby G. Sieber |
| An oil field tool for setting a Wellbore Deviation Apparatus, for deviating a wellbore, which uses an improved whipstock incorporating an elongated setting slot in the face of the whipstock, attached to a hydraulic or mechanical anchor packer is disclosed. The tool permits full drill string weight to be applied to the whipstock while the whipstock is placed in the wellbore. Additionally, the setting tool allows torque to be applied to the whipstock without prematurely releasing the deviation assembly. The same tool is used with mechanical or hydraulic packers. | ||||||
| 129 | Wireline hydraulic retrieving tool and downhole power generating assembly | US53221 | 1993-04-28 | US5398753A | 1995-03-21 | Marcel Obrejanu; David H. Weiler |
| In wireline operations, it is known to retrieve objects stuck in a well bore by means 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. Anchoring apparatus 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 is applied between the casing or tubing and the pulling tool to dislodge the object. A wireline power generating apparatus is provided to provide a controlled force in the interior of a well casing in a well bore. | ||||||

| A retrieval tool to retrieve loose pipe and the like from a well. A bell-mouth centering device is sent down the hole to center the pipe, and a spear passes through the centering device into the pipe. Gripping devices carried by the spear engage the pipe so as to pull it to the surface. The gripping devices are able to cut a thread in the pipe so as to be releasable from the pipe if desired. | ||||||
| 131 | Downhole retrieval tool | US593942 | 1984-03-27 | US4537435A | 1985-08-27 | Herman C. Carver |
| A downhole retrieval tool to recover lost wire or cable from a well. The tool has an elongated body with a smooth outer wall. A notch is formed in the wall to receive a wire to be retrieved. Within the body and operable in the notch is a latch member to trap the wire, and a trip member to release the latch member for that purpose when a wire is inside the notch. | ||||||
| 132 | Fishing tool to retrieve cables from wells | US288356 | 1981-07-30 | US4397494A | 1983-08-09 | 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 is pivotally mounted to the body so that its free end faces toward one of the ends and so that its free end is movable toward and away from the peripheral boundary. Bias means biases the shank to move the free 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 free end away from the boundary in opposition to the bias force, where it can be released upon contact with an object. The body or the snag member is provided with a snag recess to receive part of the cable. | ||||||
