| A method and apparatus for installing control lines (119, 120) and pipe (118) into a well. The work surface (116) for equipment and personnel employed in assembling the pipe is elevated above the rig floor (111). Personnel operating below the work surface (116) use clamps (121) to attach control lines (119, 120) to the pipe (118) being installed in the well. The pipe-holding spiders (113) that are normally mounted on the rig floor (111) are mounted on the elevated work surface (116). Assembling the control lines to the pipe below the work surface permits the control lines to be attached to the pipe without first travelling through the spider (113). | ||||||

| A load compensator (304) is disclosed for use in connection with a pipe running tool (10). The load compensator (304) includes an outer housing (308) connected to the portion of the pipe running tool (10) that holds the pipe segment. A piston (310) is disposed within the housing (308), and is connected to a top drive system of the pipe running tool (10). The housing (308) is formed with a first port (312) through which pressurized air is delivered inside the housing (308) to drive the piston (310) within the housing (308). A second port (314) is disposed at a selected location on the housing (308), such that when the piston (310) is advanced past the second port (314), pressurized air passes through the port (314), and causes the control circuit (306) to stop delivering air through the first port (312). Once pressurized air no longer flows through the second port (314), the control circuit (306) causes air to be delivered to the first port (312). | ||||||

| A wellbore tubular handling system and method is provided for operation in holding and lowering tubulars, such as tubing strings, casing strings, pipe strings, and the various components thereof, at a rig site. The handling system utilizes a shock table (10) with a compressible support surface (20) that compressively moves with a selected compression rate in response to the weight of the wellbore tubular string (24). The shock table (10) preferably has a shock table body (16) mounted below the rig floor (12) and supports the shock table (10) with a flange (14). A split-sectioned landing spear (30, when open, can allow large items such as collars of other string components to pass through the shock table (10). In a closed position, the landing spear (30) supports and upper collar (34) of the string (24) to thereby support the weight of the string (24) and apply the weight to the compressible support surface (20) of the shock table (10). | ||||||

| An apparatus for preventing pipe buckling when downwardly directed axial forces are applied to a pipeline (3) which extend from a derrick (1) down into a well bore, especially when snubbing. The apparatus comprises two sets of pipe supports (8) linked together to give a continuous chain (10), which is arranged to extend from a respective guide rail (6, 7) in the derrick (1) to the pipeline (3), and the pipe supports (8) are movably arranged in the guide rail (6, 7) parallel to the pipeline (3). The guide rail (6, 7) extends in a general U-shape with the U-bend (6c, 7c) located closest to the lower end of the derrick (1) and comprises two legs (6a, 6b, 7a, 7b), of which a first leg (6a, 7a) is arranged close to the pipeline (3) and a second leg (6b, 7b) is arranged at a greater distance from the pipeline. The pipe supports (8) are designed to be placed in the first leg (6a, 7a) when operative, and are designed to be transferred to the second leg (6b, 7b) when they are to be rendered inoperative. | ||||||

| An apparatus for injection of coiled tubing or jointed tubulars into a well bore, using an injector head (12) capable of handling either type of tubular. The injector head and a working platform (14) are mounted on a structure over the well head, with the injector being positioned so as to allow personnel access to the tubing on the working platform without having to relocate the injector head away from the well head location. The injector can be mounted below the working platform, or it can be mounted spaced above the working platform on a vertically movable trolley (56) on a mast. When the injector is mounted below the working platform, the tubulars and any bottom hole assembly are accessible to personnel on top of the working platform, whether coiled tubing or jointed tubulars are being used. When the vertically movable trolley is used for coiled tubing operations, the injector head can be lowered to the working platform for injection or pulling operations, and it can be raised above the working platform to give access to the tubing and the bottom hole assembly. When the vertically movable trolley is used for jointed tubular operations, the injector head can be raised above the working platform for all phases, and a movable mandrel can be used in the injector head for raising or lowering the jointed tubulars. | ||||||

| Apparatus and methods are disclosed for accessing a drill pipe bore through a drill pipe top drive unit (56). The top drive (56) is carried by a traveling block (58) so it may be used for simultaneous application of rotational and longitudinal force on the drill string. A pack-off body (12) has a shortened effective length due to mounting a flange (14) thereabouts for securing to the top drive unit (56) once a gooseneck circulation flow line has been removed in accordance with the method of the invention. A sheave support arm (24) is mounted in cantilever fashion to the pack-off body (12) and carries thereon two sheave wheels (16 and 18) provided at desired locations to direct a wireline cable (64) radially outward without frictionally engaging either the traveling block (58) and hook (88) or the top drive unit (56). The angles of bending of the wireline by placement within the support arm (24) are chosen to prevent damage to the wireline (64) containing an electrical connector. | ||||||

| L'invention concerne une méthode permettant la poursuite de mesures à l'aide d'une sonde (1) immobilisée dans un puits et reliée à la surface par un câble (4). La méthode consiste notamment à descendre une garniture tubulaire (12) concentriquement au câble (4) jusqu'à accrocher la sonde par un raccord spécial (11) fixé à l'extrémité de la garniture. Les tubulaires servent à la protection du câble. On utilise un raccord à fenêtre latérale (28) pour minimiser le temps de manoeuvre. Après accrochage, la sonde est utilisée pour faire des mesures en déplaçant la garniture tubulaire. | ||||||
