| 41 | Device for gripping an object in a constrained space | US14718035 | 2015-05-20 | US09909394B1 | 2018-03-06 | David G. Hosie |
| A gripper assembly for gripping coiled tubing with lower and upper ball carriers. A first gripper portion and a second gripper portion each have a channel for a bore through the gripper portions. Gripper portions can rotate in relation to each other. Rotation causes the gripper portion to close around an object that passes through the bore. With a translational force, the gripper portions rotate relative to each other to grasp an object. | ||||||

| 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. | ||||||

| 44 | Support system, excavation arrangement, and process of supporting an object | US14032341 | 2013-09-20 | US09719349B1 | 2017-08-01 | Bill W. Arnold |
| A support system, an excavation arrangement, and a process of supporting an object are disclosed. The support system includes a weight-bearing device and a camming mechanism positioned below the weight-bearing device. A downward force on the weight-bearing device at least partially secures the camming mechanism to opposing surfaces. The excavation arrangement includes a borehole, a support system positioned within and secured to the borehole, and an object positioned on and supported by the support system. The process includes positioning and securing the support system and positioning the object on the weight-bearing device. | ||||||

| In one aspect, a wellbore system including a longitudinal member disposed within a wellbore; a retention device associated with the longitudinal member, wherein the retention device is configured to deploy in response to a critical fluid flow rate to decelerate the longitudinal member subject to an unimpeded travel within the wellbore. In another aspect, a method of retaining a longitudinal member within a wellbore, including providing the longitudinal member within the wellbore; associating a retention device with the longitudinal member; subjecting the longitudinal member to an unimpeded travel within the wellbore; deploying the retention device in response to a critical fluid flow rate; and decelerating the longitudinal member within the wellbore via the retention device. | ||||||
| 46 | TUBING ANCHORING AND MOVEMENT REDUCING SYSTEM | US14710303 | 2015-05-12 | US20150259998A1 | 2015-09-17 | EDWARD L. MOORE |
| 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. | ||||||
| 47 | Tubular catcher system and method | US13664228 | 2012-10-30 | US09057246B2 | 2015-06-16 | Jonathan Brian O'Blenes |
| Present embodiments are directed to a tubular catcher system configured to detect a falling tubular through a drilling rig and grip the tubular before it drops into the wellbore. A sensor configured to detect the velocity or acceleration of the tubular activates an actuation mechanism when the velocity or acceleration exceeds a specific threshold, indicating a falling tubular. The actuation mechanism forces a gripping mechanism into contact with the tubular, catching the tubular and sending energy from the tubular to a hydropneumatic shock absorber coupled to the actuation mechanism and/or the gripping mechanism. | ||||||

| A capture basket system for use below an underdeck pipehandling machine on a drill rig. The capture basket system includes a capture basket to retain a falling object such as a pipe. The capture basket is coupled to a structure of the drill rig by an energy absorber that includes an elongated element. | ||||||

| 50 | Braking device for tool strings | US10275597 | 2003-07-24 | US20040011533A1 | 2004-01-22 | Lewis Lawrence; Brian Scott; David Martin; Graeme Makin; Stuart Ferguson |
| An embodiment of the invention discloses a restraint mechanism (12) of a braking device (10) for location in tubing (16) such as the casing of an oil or gas well. The braking device (10) forms part of a tool string which is run into the tubing (16) on a wireline and, in the event that the wireline breaks or is severed, the braking device (10) and the associated tool string falls through the tubing. The restraint mechanism (12) includes a sensor assembly (18), and a brake mechanism (22). The sensor assembly (18) senses the uncontrolled movement and provides an appropriate output causing activation of the brake mechanism (22), bringing the braking device (10) and tool string to a controlled stop. | ||||||
| 51 | Wire line no-blow tool | US307910 | 1981-10-02 | US4427064A | 1984-01-24 | Michael L. Bowyer |
| No-blow tool for braking rapid upward movement of a pulling tool and the device being retrieved caused by sudden upward fluid flow. The no-blow tool is assembled as part of a wire line tool assembly below jars and above the pulling tool. The no-blow tool includes three telescoping members, the lowest of which is secured to the pulling tool. Rapid upward movement of the pulling tool and the lowest telescoping member relative to the intermediate telescoping member cams serated slips radially outwardly to grip a well conduit, thereby braking the upward movement. A shearable connection between the upper and intermediate telescoping members permits jarring forces to be transmitted downwardly through the tool, without interference from the slip system. | ||||||

| Present embodiments are directed to a tubular catcher system configured to detect a falling tubular (30) through a drilling rig (10) and grip the tubular (30) before it drops into the wellbore. A sensor (44) configured to detect the velocity or acceleration of the tubular (30) activates an actuation mechanism (46) when the velocity or acceleration exceeds a specific threshold, indicating a falling tubular (30). The actuation mechanism (46) forces a gripping mechanism (48) into contact with the tubular (30), catching the tubular (30) and sending energy from the tubular (30) to a hydropneumatic shock absorber (90) coupled to the actuation mechanism (46) and/or the gripping mechanism (48). | ||||||
