| In one embodiment, the present disclosure provides an apparatus and method for supporting a tubing bundle during installation or removal. The apparatus includes a clamp for securing the tubing bundle to an external wireline. In various examples, the clamp is external to the tubing bundle or integral with the tubing bundle. According to one method, a tubing bundle and wireline are deployed together and the tubing bundle periodically secured to the wireline using a clamp. In another embodiment, the present disclosure provides an apparatus and method for coupling conduit segments together. A first pump obtains a sample and transmits it through a first conduit to a reservoir accessible by a second pump. The second pump further conducts the sample from the reservoir through a second conduit. In a specific example, one or more clamps are used to connect the first and/or second conduits to an external wireline. | ||||||

| A method and device for preventing a pipe string (5) clampingly arranged in a slips (2) from slipping out of the slips (2) in the event of the pipe string (5) slipping in the slips (2), wherein a pipe clamp (22) is clamped, preferably hydraulically, onto the pipe string (5) at a position above the slips (2) and maintained in the clamped state for essentially as long as the pipe string (5) is held by the slips (2), the pipe clamp (22), in the event of the pipe string (5) slipping in the slips (2), being displaced together with the pipe string (5) until the pipe clamp/tong (22) stops against the wedges (16) of the slips (2). | ||||||
| 145 | Pump rod clamp and blowout preventer | US10810704 | 2004-03-29 | US07000888B2 | 2006-02-21 | Andrew J. Wright; James Bentley |
| A pump rod clamp for gripping a pump rod in an oil, gas or water well. The pump rod clamp comprises a central housing having a longitudinal bore for receiving a pump rod, a plurality of clamping members receivable within the central housing, and one or more actuators to cause the clamping members to be moved between an activated position where they grippingly engage the pump rod and a deactivated position where they are released from contact with the pump rod. Each of the clamping members have a leading face that includes one or more gripping inserts releasably secured thereto. The gripping inserts having outer faces generally aligned with the pump rod for grippingly engaging the pump rod when the clamping members are in their activated position such that force exerted by each individual clamping member against the pump rod is concentrated and distributed over the outer faces of the one or more gripping inserts of each clamping member. | ||||||
| 146 | Method and system for avoiding damage to behind-casing structures | US10082469 | 2002-02-25 | US20030159826A1 | 2003-08-28 | Herve Ohmer |
| A structure is positioned on the outer surface of a casing or liner to enable cutting the casing in substantially any azimuth over a given length of casing without damaging the structure. After placing the casing in a wellbore, the position of the structure on the casing may be determined with reference to an orienting slot in an indexing coupling. Thereafter, a non-colliding region on the casing may be identified for cutting the casing. | ||||||
| 147 | T-bar wireline clamp | US917506 | 1997-08-26 | US5979022A | 1999-11-09 | Larry V. Cooper |
| A heavy duty clamp for cables or wires, and the like, said clamp having increased strength and resistance to distortion or breakage. Two overlying clamp plates, or segments, are held against relative movement by one of the plates having a shoulder member that engages with a portion of the other plate. The plates contain a split, tubular gripping member and the plates have increased longitudinal strength by having extended ends of the plates to provide protection against shearing forces created by the split tubular gripping member against the adjacent ends of the clamp plates. | ||||||
