20150345235 | A WELL INTERVENTION CABLE BENDING RESTRICTION FOR A RIGID RESILIENT ROD-SHAPED INTERVENTION CABLE - 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. | 12-03-2015 |
20150315861 | WELL OPERATION METHOD AND A WELL OPERATION EQUIPMENT SYSTEM FOR HANDLING A CONTINUOUS ELONGATE DEVICE TO BE INSERTABLE INTO A WELL - A well operation method and system for handling a continuous elongate device (CED) ( | 11-05-2015 |
20140060807 | INJECTOR FOR LOGGING OR INTERVENTION STRING - A well logging- or well intervention string injector includes two adjacent motorized endless chains with gripper elements for bearing against the string. The gripping elements have an engagement packer against the string. The gripping elements run over the back supporting rollers carried by separate back supporting roller brackets. The back supporting roller brackets further bear against an elongated hydrostatic pressure equalizing cushion with hydraulic fluid. The pressure equalizing cushion bears against a back supporting rail. | 03-06-2014 |
20140014317 | DRUM UNIT WITH AN ARCH COMPENSATOR FOR A WELL INTERVENTION STRING - A drum unit for an intervention string for a well includes a drum with a drum axis and with a radius, arranged in a structural frame and rotatable by a motor and a tension compensator. The tension compensator includes a guide arch displaceable in a direction generally along the intervention string, orthogonal to the drum axis, using a first force device connected to the structural frame for keeping the intervention string in tension. At least a first end of the guide arch is laterally displaceable in a direction generally orthogonal to the intervention string, parallel with the drum axis. The intervention string runs between the guide arch to or from the first end to the drum. The intervention string runs via a second, opposite end of the guide arch via a second, fixed guide at the structural frame, directly or indirectly to or from the well. | 01-16-2014 |
20130161441 | DRUM UNIT FOR A WELL INTERVENTION STRING - A drum unit for an intervention string for a well includes a drum with a radius for the intervention string, arranged in a structural frame and rotatable by a motor, the drum being arranged translating along a drum axis and driven by a translation motor, for controlled winding of the intervention string onto the drum relative to a first, fixed guide in the structural frame. A compensator includes a guide arch, the guide arch being displaceable in a direction orthogonal to the drum axis using a force device at the structural frame. The intervention string runs between the guide arch and the first fixed guide to or from a first end of the guide arch to the drum. The intervention string runs via a second, opposite end of the guide arch via a second, fixed guide at the structural frame, to or from the well. | 06-27-2013 |
