Abstract: A silicone composite for high temperature insulation applications is disclosed. The composite is formed of a silicone and a thermally decomposable inorganic filler which are compounded together. The compounded material is then injection molded, overmolded, compression molded, cast, laminated, extruded, or dispensed. When the silicone composite is exposed to a high temperature, it forms an inorganic composite and maintains its insulating properties and dimensional stability.

Abstract: A process for welding a conductor onto a workpiece includes providing the conductor including a first metal, providing the workpiece including a second metal, removing an insulation of the conductor over a predetermined length, and forming a bead in a stripped region of the conductor. The conductor is held down on the workpiece to produce a mechanical contact in a welding region between the conductor and the workpiece. The welding region is arranged in a region of the bead. The conductor is laser welded to the workpiece in the welding region.

Abstract: A wellbore communication system (1) comprises a downhole tool (2) having a downhole transmitter (40), a sensing element (22, 122, 222, . . . , 1022) located at surface and coupled to a surface receiver (44), and an insulated slickline (6, 106, 206, . . . , 1006) having an electrically conductive core surrounded by an insulating coating. The slickline is attached to the downhole tool and coupled to the downhole transmitter. The sensing element is capacitively coupled to the slickline so as to permit movement of the slickline relative thereto and so as to an electric field to extend from the core of the slickline through the insulating coating to the sensing element for transmission of information from the downhole transmitter to the surface receiver via the slickline and the sensing element.
