Abstract: A method for forming an insulated conductor heater includes placing an insulation layer over at least part of an elongated, cylindrical inner electrical conductor. An elongated, cylindrical outer electrical conductor is placed over at least part of the insulation layer to form the insulated conductor heater. One or more cold working/heat treating steps are performed on the insulated conductor heater. The cold working/heat treating steps include: cold working the insulated conductor heater to reduce a cross-sectional area of the insulated conductor heater by at least about 30% and heat treating the insulated conductor heater at a temperature of at least about 870° C. The cross-sectional area of the insulated conductor heater is then reduced by an amount ranging between about 5% and about 20% to a final cross-sectional area.

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 magetic orienting tool that is located within the wellbore tubular.

Abstract: A method of providing optical fiber in a wellbore may include lowering a spindle holding the optical fiber through the wellbore and anchoring a distal end of the optical fiber in the wellbore. The method may also include drawing the optical fiber from the spindle by pulling the spindle back through the wellbore. A device for providing optical fiber in a wellbore may include a spindle configured to hold at least a portion of the optical fiber as the spindle moves through the wellbore. The optical fiber is drawn from the spindle as the spindle passes through the wellbore.

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.

Abstract: An insulated electrical conductor (MI cable) may include an inner electrical conductor, an electrical insulator at least partially surrounding the electrical conductor, and an outer electrical conductor at least partially surrounding the electrical insulator. The insulated electrical conductor may have a substantially continuous length of at least about 100 m. The insulated electrical conductor may have an initial breakdown voltage, over a substantially continuous length of at least about 100 m, of at least about 60 volts per mil of the electrical insulator thickness (about 2400 volts per mm of the electrical insulator thickness) at about 1300° F. (about 700° C.) and about 60 Hz. The insulated electrical conductor may be capable of being coiled around a radius of about 100 times a diameter of the insulated electrical conductor. The outer electrical conductor may have a yield strength based on a 0.2% offset of about 100 kpsi.
