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 |

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 |

20130160988 | FLEXIBLE ROUTING DEVICE FOR WELL INTERVENTION - A conduit device for a petroleum well intervention string includes a first end connected to an intervention string drum unit with a drum and a second end connected to an injector head of a wellhead assembly. The conduit device, at any point between said first end and said second end, has a radius of curvature larger than or equal to a given smallest allowable radius of curvature for the intervention string. The conduit device forms a substantially incompressible fixed length path for the portion of said intervention string at any time present between the first end and the second end. The conduit device constitutes a tubular path for the intervention string. | 06-27-2013 |
