Title: Fluid pipeline leak detection and location with miniature RF tags

Abstract

Sensors locate troublesome leaks in pipes or conduits that carry a flowing medium. These sensors, through tailored physical and geometric properties, preferentially seek conduit leaks or breaches due to flow streaming. The sensors can be queried via transceivers outside the conduit or located and interrogated inside by submersible unmanned vehicle to identify and characterize the nature of a leak. The sensors can be functionalized with other capabilities for additional leak and pipeline characterization if needed. Sensors can be recovered from a conduit flow stream and reused for future leak detection activities.

  • A method and apparatus for the detection of leaks in an interconnected pipeline system are disclosed. The method involves recording flow characteristics over a specific, short time period, e.g., one-half hour daily, at control stations distributed throughout the network. By arranging the control stations in this manner, subnetworks are defined and the existence of leaks therein determined in accordance with deviations in measurements which facilitate localization procedures for the leaks. The apparatus is a well for use at the control stations immovably fixed in the network and accessible from the outside.
  • This patent describes a method for the location of a leak in a subsea hydrocarbon pipeline. It comprises: transmitting acoustic waves into the pipeline, the waves traveling through a rupture in the pipeline causing the leak; towing an array of hydrophones in the vicinity of the pipeline; knowing the relative location of each of the hydrophones in the array; and correlating the intensity of the acoustic waves received by each hydrophone will the known location of each hydrophone to calculate the location of the leak.
  • For sealing a pipeline at selective locations in order to perform leak tests, a pipeline packer assembly capable of internal travel within the pipeline can be moved to and stopped at selected locations and the packer inflated against the interior pipe walls to prevent further movement of the unit, and to provide a seal so that the pipeline may be subjected to internal high pressures to detect leaks. According to the invention, a control device for such unit comprises a gamma ray detector and signal processor receiving the electrical analogue signal from the gamma ray detector. An energizing signal frommore » the signal processor actuates a stepping switch which provides ''inflate'' and ''deflate'' energization of the packer, and is kept in ''off'' condition while the packer is inoperative as in transit within the pipeline. A radiation source on the surface or selectively inserted into a bore hole near the pipeline provides a stimulus for the gamma ray detector which controls the operation of the stepping switch. The insertion and subsequent withdrawal of the radiation source from the vicinity of the pipe adjacent the control unit, successively causes the successive stepping of the stepping switch to ''inflate'', ''deflate'' and ''off'' conditions. The assembly is moved through the pipeline at low pressure, and the pipeline subjected to high pressure behind the packer when it is inflated, thereby to permit leak detection at successive locations within the pipeline.« less
  • A method and device are disclosed that provide for detection of fluid leaks in analytical instruments and instrument systems. The leak detection device includes a collection tube, a fluid absorbing material, and a circuit that electrically couples to an indicator device. When assembled, the leak detection device detects and monitors for fluid leaks, providing a preselected response in conjunction with the indicator device when contacted by a fluid.
  • Fluid in a pipeline or container at a refinery or at any of various petroleum producing operations is bombarded with neutrons, and high energy gamma rays resulting from capture of thermal neutrons are detected. The spectra of the detected gamma rays are then analyzed to determine the concentration of the element chlorine, which gives an indication of the presence and concentration of salt water in the fluid. The concentration of sulfur and the percentage gas in the fluid may be determined simultaneously with the concentration of chlorine.
