Abstract: A cost efficient and pressure resistant system for interconnecting fiber optical cables in-situ at a hydrocarbon fluid production facility comprises:—a pressure resistant light transparent window (41);—a first lens system (48A-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 (46A-C) into a collimated light beam (51A-C) that is transmitted through the window; and—a second lens system (50A-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 (47A-C).

Abstract: 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.

Abstract: 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 μr,m 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.

Abstract: 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.
