| 6 | Shearing gate valve | JP1473390 | 1990-01-24 | JPH0360910A | 1991-03-15 | JIERARUDO ESU BEIKAA |
| PURPOSE: To prevent damage to a gate by forming sleeves and inset rings from a hard wear resistant material, and mounting and keeping the sleeves and the insert rings in respective positions under compressive preloads such that they resist damage during the operations of closing, sealing, and shearing a valve. CONSTITUTION: Seat rings 34, 36 made of tungsten carbide or the like which has little tensile strength are fitted into dents 38, 40 in a main body 12, and prior to assembly the inner dent is given a smaller bore than that of insert rings 46, 48 and heated in order to permit the insertion of the insert rings 46, 48 without application of undue load. A gate 32 is connected to a connecting rod 30 and is heated and shrink fitted to allow a sleeve 44 of hard material to be easily inserted into an opening 42. Therefore a wire or the like which passes through a gate valve 10 can be sheared without causing damage to the hard inserts 46, 48 and the hard sleeve 44, and the valve 10 is used without repair through a number of cycles of closing and shearing.

| 8 | A DOWNHOLE TOOL | EP12843707.6 | 2012-10-26 | EP2771537B8 | 2018-08-01 | MANSON, David |
| A downhole tool mechanism for applying a driving force, such as a cutter tool for cutting a line captured within the tool, comprises a resiliently compressible member for storing a compressive force; a retaining device for maintaining storage of the compressive force until released; a trigger mechanism for releasing the compressive force when the trigger mechanism is activated. In one form the resiliently compressible member comprises a plurality of concentrically arranged spring washers each having a radial slot therein for receiving a line along the length of the resiliently compressible member. In the cutter form, there is a cutter arranged to cut the line when the trigger mechanism is activated, and the trigger mechanism is activated when the tool receives a shock force to one or both ends. | ||||||

| A method and apparatus for releasing a coiled tubing internal line from a bottom hole assembly. The internal line may not have strength sufficient to permit the application of a tension force at the surface to disconnect the internal line from the bottom hole assembly. The bottom hole assembly may include a ball scat adapted to retain a ball permitting the application of a pressure differential above and below the ball seat. An anchor assembly connected to the internal line may be adapted to disconnect from the bottom hole assembly upon the application of predetermined pressure differential. A predetermined pressure differential may be used to shear a portion of the internal line releasing an upper portion of the internal line from the bottom hole assembly. | ||||||

| Method for cutting of at least one line (38, 40, 42, 44) disposed along a pipe string (16) in a well (2), comprising: (A) using a cutting tool (48) for selective cutting activation and provided with at least one cut-forming means (54, 56, 58, 60) for cutting in a radial direction outward from the cutting tool (48); and (B) lowering the cutting tool (48) to a longitudinal section (L1) where the cutting is to be carried out. The distinctive characteristic is that of using, in step (A), a cutting tool (48) for controlled cutting, by means of said means (54, 56, 58, 60), in a peripheral direction and distributed in an axial direction relative to the cutting tool (48); and (C) activating the cutting tool (48) and cutting, in the radial direction through and past the wall of the pipe string (16), at least one peripherally extending hole (62, 64, 66, 68) collectively covering the entire circumference of the pipe string (16), and also distributing the hole (62, 64, 66, 68) in the axial direction. | ||||||

| 17 | TOOL AND METHOD FOR ESTABLISHING HYDRAULIC COMMUNICATION WITH A SUBSURFACE SAFETY VALVE | EP08729775.0 | 2008-02-13 | EP2122119A2 | 2009-11-25 | MAILAND, Jason, C.; BAHR, Glenn, A. |
| A communication tool apparatus is described which is adapted to provide selective communication of control fluid through a downhole device such as a safety valve. The downhole safety valve is a tubing retrievable subsurface safety valve (“TRSSSV”). The communication tool may be run downhole and within the TRSSSV. Once within the TRSSSV, the communication tool apparatus activates a cutting device within the TRSSSV such that communication of control fluid through the TRSSSV is possible. A replacement safety valve run on a wireline may then be inserted into the TRSSSV and be operated via the control fluid line, as a new communication path created by the communication tool described herein. A method of using the communication tool apparatus is also described. | ||||||

| A pipe string in an oil well has a cable (2) slidingly attached along it. It may be necessary to break the pipe string. Apparatus is provided for controlling the position of a fracture in the cable, as it is desirable to break the cable at about the same point. The apparatus comprises a pocket (1) attached to the cable and having a passage through which the cable passes, and upper and lower nipples (5 and 6) attached to the cable in the pocket. The lower face (5') of the nipple (5) is skewed relative to the lower internal face (3') of the pocket and the facing faces (5', 6') of the two nipples are skewed relative to each other, so bending and kinking the cable when tension is applied. The cable therefore breaks at the bend or kink. The pipe string includes a plurality of such apparatuses located at spaced points along its length. | ||||||
| 20 | Ball valve | EP95302877.6 | 1995-04-27 | EP0679796A3 | 1997-01-02 | Noack, Timothy; Allred, Wesley R. |
A ball valve which can be used to cut coiled tubing extending therethrough, includes a ball (154) rotatably disposed within a housing and adjacent to a seat (152). Control arms (156,158) prevent relative longitudinal movement between the ball (154) and seat (152). The ball defines a pair of slots (202,204) therein, each slot having a bearing surface. A pair of control pins (164,166) are disposed on opposite sides of the ball and rotatably disposed in corresponding control frames (160,162) disposed on opposite sides of the ball. Each control pin (164,166) has an end (208) with a bearing surface (206,212) thereon extending into a corresponding slot (202,204) in the ball so that flat contact is provided between the control pin and the ball. This greater area of contact between the pins (164,166) and the slots (202,204) allows a greater load to be transmitted to the ball to provide the shearing load necessary to shear relatively large diameters of coiled tubing which extend through the open valve. The valve is opened and closed by pressure actuation of a piston. |
