| A bending restrictor for a rigid but resilient rod-shaped intervention cable includes a series of pipe sections and articulation sleeves. Each pipe section includes a straight pipe piece with a spherical sector in either end. Each articulation sleeve includes two axially oppositely directed spherical-sector seats for holding about each pipe's spherical sector. The spherical sector seats are arranged in either ends of a central axial passage for the intervention cable. Two guide sheaves each with its sheave groove reside in the articulation sleeve's axial plan is laterally displaced relative to the middle of the axial passage so as for enveloping the axial passage for the intervention cable. The articulation sleeve is provided with two opposite axially directed and flattened pivot funnels, and each pivot funnel is provided with its narrower end in adjacent to each its spherical-sector seat. Each pivot funnel has, in the axial plane a funnel shape which allows the pipe section's straight pipe piece to pivot about the spherical sector seat in the axial plane, and wherein the pivot funnel's funnel shape is flattened in another axial plane perpendicular to the first axial plane, so as for the pipe sections to be able to pivot only in the first axial plane. The articulation sleeve is splittable in the plane into two articulation sleeve half housings. | ||||||

The invention provides a method and a system for expanding a tubular element. The tubular element comprises a wall which is bent radially outward and in axially reverse direction defining an expanded tubular section extending around an unexpanded tubular section. The system comprises: pipe production means for extending the unexpanded section of the tubular element; a pipe pusher for pushing the unexpanded section into the expanded section to expand the tubular element; and moveable guide means for receiving the tubular element from the pipe production means or from the pipe pusher, and for guiding the tubular element towards a wellhead selected from a multitude of wellheads. The moveable guide means may comprise a flexible guide conduit for receiving and guiding the tubular element. The method includes guiding the tubular element to another wellhead using the guide means, without moving the rest of the equipment.

| A coiled tubing support guide for maintaining an arch in a length of coiled tubing as it is unwound from a storage reel and feed into a coiled tubing injector connected with a wellhead is mounted to an elongated support structure rather than to the coiled tubing injector. The elongated support structure bears a load created by tension placed on the coiled tubing by the reel, thereby avoiding putting a bending moment on the wellhead. In alternate embodiment, a coiled tubing injector being held by a hoist line from the elongated support structure is coupled to the elongated support structure with a bending-resistant coupling that permits relative rotation of the coiled tubing injector. | ||||||

| The invention relates to a handling device for drill pipes (18) and to a so-called top drive (16) gripping said handling device, a so-called pipe handler, having means for detecting a position of elevator equipment (30) gripped by the handling device/pipe handler and for forwarding the associated positional information. The positional information is forwarded from the pipe handler to, for example, the top drive (16) and is converted into an electrical signal for detecting and avoiding possibly critical situations as a result of a position/deflection of the elevator equipment (30). | ||||||
| 157 | DRUM LOAD MONITORING | EP10789096.4 | 2010-06-17 | EP2443308A2 | 2012-04-25 | BRADY, Dominic |
| An assembly for monitoring load on a drum during an operation in a well with a well access line deployed from the drum. The assembly may include multiple line detection mechanisms for acquiring real-time information relative to dynamic characteristics of the lone over the course of the operation. The assembly also includes a processor for computing the real-time information in light of pre-stored information relative to physical characteristics of the line and the drum. As a result, real-time monitoring of a load on the drum may be achieved. Thus, the operation may be adjusted in real-time as necessary to avoid over- loading of the drum. Additionally, a drum load history may be recorded so as to better account for the true condition of the drum following successive operations. | ||||||
