A system for providing information through a metal wall employs a device adapted to be arranged on one side of the metal wall and a magnetic-permeability element, provided at, near or connected to the device. The magnetic-permeability element is based on a material having a relative magnetic permeability of at least 2000. The disclosure also provides use of said system. The use may involve the step of optimizing the magnetic-permeability element using equivalent inductive mass (EIm). The system can for example be used to magnetically sense the location of a cable present on the outside of a wellbore tubular using a magnetic orienting tool that is located within the wellbore tubular.

Cable system for downhole use and method of perforating a wellbore tubular

A metal wellbore tubular wall of a wellbore tubular, having a cable system arranged on an outside thereof, is to be perforated downhole. The cable system contains a fiber-optic cable, and a magnetic-permeability element with a relative magnetic permeability &#x3bc;of at least 2,000, such as an electrical steel, is configured along a length of the fiber-optic cable. The cable system is located by sensing the magnetic-permeability element through the metal wellbore tubular wall, using a magetic orienting tool which is being lowered into the wellbore tubular. subsequently, the metal wellbore tubular wall is perforated in a direction away from the cable system.

A flow velocity meter, for measuring flow velocity of a fluid, has a distributed acoustic sensor along aq longitudinal direction, which has a distributed sensing element. The distributed sensing element is acoustically coupled to a distributed fluid-contact surface via a distributed acoustic path extending between the distributed fluid-contact surface and the distributed sensing element. Moreover the distributed acoustic path is fully bypassing the fluid. At least a part of the fluid-contact surface is provided with a flow-disturbing surface texture having a surface relief with a pre-determined pattern in said longitudinal direction. Acoustic flow noise, emitted as a result of the fluid flowing along and in contact with the flow-disturbing surface texture, is picked up by the distributed sensing element as a distributed acoustic signal.

A cost efficient and pressure resistant system for interconnecting fiber optical cables in-situ at a hydrocarbon fluid production facility comprises:&#x2014;a pressure resistant light transparent window ();&#x2014;a first lens system (A-C), which is arranged at one side of the window and configured to convert a first light beam transmitted through a first fiber optical cable (A-C) into a collimated light beam (A-C) that is transmitted through the window; and&#x2014;a second lens system (A-C), which is arranged at an opposite side of the window and configured to receive and reconvert the collimated light beam into a second light beam that is transmitted into a second fiber optical cable (A-C).

Interconnecting optical fibers at a hydrocarbon fluid production facility

A method for adapting a tubular element extending into a wellbore formed in an earth formation, where the tubular element is susceptible to damage caused by axially compressive forces acting on the tubular element as a result of compaction of the earth formation surrounding the tubular element. The method comprises the steps of reducing the axial stiffness of at least one section of the tubular element, and allowing each tubular element section of reduced axial stiffness to be axially compressed by the action of said axially compressive forces, thereby accommodating compaction of the earth formation surrounding the tubular element.

Method for adapting a tubular element in a subsiding wellbore

A method is provided of applying an annular seal to a tubular element () for use in a wellbore (). The method comprises the steps of: a) providing at least one flexible seal layer () at the wellbore site, each seal layer having a pair of opposite longitudinal edges movable relative to each other between an open position wherein the seal layer can be radially applied to the tubular element, and a closed position wherein the seal layer extends substantially around the tubular element, the seal layer being made material susceptible of swelling upon contact with a selected fluid; b) partially lowering the tubular element () into the wellbore (); c) radially applying the seal layer () in the open position thereof to a portion of the tubular element extending above the wellbore; d) moving the seal layer () to the closed position thereof; and e) further lowering the tubular element () with the seal layer () applied thereto into the wellbore () until the seal layer is located at a selected location in the wellbore ().
