  • Publication number: 20190369152
    Abstract: The invention relates to a method for cable condition monitoring of an electric cable. The method comprises inducing a test current in the electric cable, measuring a resulting current in a measurement point of the electric cable by measuring a magnetic nearfield of the electric cable, measuring a resulting voltage in the measurement point of the electric cable by measuring an electric nearfield of the cable, calculating an impedance of the electric cable based on the resulting current and the resulting voltage by a line resonance analysis system, and analysing the impedance by the line resonance analysis system establishing a condition of the electric cable. A coupler arrangement providing a non-galvanic connection to the cable is also disclosed.

  • Patent number: 8726726
    Abstract: The present invention concerns a dynamic pressure sensor unit (5A) for a logging tool for hydrocarbon wells with a piezoelectric element (5) in a sensor sleeve (3). The piezoelectric element (5) is a tubular element with an inner and an outer diameter. The sensor sleeve (3) has an inner cylindrical area with an inner diameter greater than the outer diameter of the tubular piezoelectric element (5). The piezoelectric element is situated in the inner cylindrical area of the sensor sleeve (3). A gap (12) with a gap thickness is formed between the inner cylindrical area of the sensor sleeve (3), defining an annular volume. The gap is filled with a noise transmitting liquid.

  • Patent number: 8370089
    Abstract: A method and equipment are provided for determining the level/height, of one or more interfaces between two or more fluid phases of different density that are contained in a vessel, tank or the like. The position of the different interfaces in a tank is determined by measuring the pressure thereby determining the density of the fluid over the height of the tank by using a pressure measuring rod, equipped with pressure sensors, positioned in the tank. A mathematical model or algorithm is used which calculates how the density and hence the pressure vary over the height of the tank as a function of the fluid properties of the respective fluids in the tank, the interface, on the basis of the density being the same within each layer of the respective fluid, as a respective point at which the density changes from one layer to the next in the tank.

  • Publication number: 20130016582
    Abstract: A system for communication through subterranean structures underneath a surface comprises at least one exploration tool adapted to penetrate into the underground, at least one transmitter, at least one receiver, and signal transfer means for transmitting signals between the exploration tool and a recording unit arranged overground, where at least one of the transmitter or receiver is integrated in the exploration tool. The exploration tool is a device which is able to penetrate into the underground in order to bring equipment into the underground independent of any existing or new wells.

  • Publication number: 20120091732
    Abstract: The present invention concerns a power generating apparatus for generating power from a fluid flowing in a pipe (14). The apparatus includes a cylindrical body (13), and an annular turbine (4) for driving an electric generator. Fluid bearings (8, 9, 10) support the turbine (4). A central flow passage (17) extends through the entire power generating apparatus. A fluid conditioner stage removes contamination of solid particles from the fluid, for conditioning the fluid before entering the fluid bearing (8, 9, 10), lubricated by the fluid. A first static flow shaper (1) is included in the fluid conditioner stage for providing a rotating vortex flow acting to concentrate the contamination of solid particles in a flow along an outer circumference of the apparatus and an uncontaminated flow to the bearings (8, 9, 10).
