    Abstract: Systems and methods include a system for processing health information for multiphase flow meters (MPFMs) of different types and at one or more different locations. Multiphase flow meter (MPFM) readings of different MPFM types are received in real-time from MPFMs at different locations. For each MPFM, an MPFM health rule that corresponds to the MPFM readings is determined using the MPFM readings and logic of MPFM health rules. A recommendation is determined for each MPFM based on the MPFM health rule. A health status and an alarm priority are determined for each MPFM using the MPFM readings and the logic of MPFM health rules. A dashboard is presented to a user that includes, for each MPFM, the MPFM readings, the recommendation, the health status, and the alarm priority.

  • Patent number: 10908131
    Abstract: Apparatus and methods for the measurement of gas volume fraction of produced oil are described. A first method measures the response of a pipe containing the produced oil excited by a source of vibration in the form of an acoustic frequency chirp containing a linearly varying range of frequencies in the tens of kilohertz range encompassing at least one resonant mode of the pipe. As the gas volume fraction increases, the location of the peak maximum of the measured frequency spectrum responsive to the excitation increases in frequency, and the height of the peak maximum increases, thereby permitting a linear calibration curve to be obtained. A second method measures the response of a pipe containing the produced oil to excitation by a continuous source of vibration having a chosen frequency above those which excite flexural vibrations in the pipe and simultaneously excite acoustic waves in the fluid contained in the pipe, known as the coincidence frequency.

  • Patent number: 10634537
    Abstract: An apparatus, system, and method for use in determining at least one property of a flowing multiphase fluid involves comparing an initial signal and a pair of local reference signals with a set of flow characteristics extracted from reference sensor feature maps wherein the signals are related to the flow of the multiphase fluid as it passes through a flow passage which is continuously monitored, adjusted, and calibrated. Based upon the comparison, a decision is made to either resume monitoring of the flowing multiphase fluid by using a pair of local reference signals which are closely positioned and defined, or to adjust the flow passage area significantly in order to improve metering flow conditions. The invention is best suited for determining transport flow velocity and gas void fraction or relative proportions of the gas phase and the liquid phase within the multiphase fluid which subsequently can be used to quantify gas and liquid flowrates.

    Abstract: Tomographic reconstruction is performed of cross-sectional images of downhole or surface multiphase flows containing water (brine), oil, and gas phases. Measures are obtained of digital transmission (or analog attenuation) and also of analog transit time to form two views of the same cross sectional flow in a location of interest in a flow conduit. The measures are then merged by synthesizing a composite image of the multiphase flows. Rather than performing a complex tomographic reconstruction requiring a large number of calculations, measures are also obtained directly from the tomographic pattern which can be used to reconstruct an approximation of the cross sectional flow by the superposition of circles of variable position, radius and density representing flow patterns.

  • Patent number: 9424674
    Abstract: Tomographic reconstruction is performed of cross-sectional images of downhole or surface multiphase flows containing water (brine), oil, and gas phases. Measures are obtained of digital transmission (or analog attenuation) and also of analog transit time to form two views of the same cross sectional flow in a location of interest in a flow conduit. The measures are then merged by synthesizing a composite image of the multiphase flows. Rather than performing a complex tomographic reconstruction requiring a large number of calculations, measures are also obtained directly from the tomographic pattern which can be used to reconstruct an approximation of the cross sectional flow by the superposition of circles of variable position, radius and density representing flow patterns.

    Abstract: The present invention relates to a Coriolis mass flow meter, a vibrating tube density meter and a vibrating sheet used therein, and more particularly, to a vibrating sheet for use in a Coriolis mass flow meter or a vibrating tube density meter, the vibrating sheet having at least one welded connecting portion that is fixedly welded to the flow tube of the Coriolis mass flow meter or the vibrating tube density meter, the flow tube being excited to vibrate around a revolving axis at the welded junction of the vibrating sheet and the flow tube. The welded connecting portions of the vibrating sheet are only formed in the stress insensitive region of the vibrating sheet, wherein the stress insensitive region is the region of the vibrating sheet which has an angle of not more than 45 degrees with respect to the revolving axis. In addition, the present invention also provides a Coriolis mass flow meter and a vibrating tube density meter using the vibrating sheet.

  • Patent number: 9347310
    Abstract: Multiphase flow measurement in extreme environments such as subsea or in-well is a difficult task for many reasons including reliability, survivability, and longevity issues; accessibility to the equipment; and complexity of the varying flow field as a function of position and time. Embodiments of the present invention provide techniques and apparatus for performing subsea multiphase flow measurement by combining two technologies. One is based on infrared water-cut measurement technology which is capable of measuring water and oil concentrations in multiphase flow with up to 99.5% gas volume fractions. The second technology is based on in-well fiber-optic flow measurement capable of resolving gas and total liquid flow through the measurements of flow velocity, fluid mixture speed of sound, and absolute pressure and temperature at meter location. This hybrid system represents an approach to subsea multiphase metering that may offer advantages compared to traditional systems for some applications.

  • Patent number: 9316518
    Abstract: The method for measuring the flow rate of a multi-phase liquid determines the speed of sound and the density of each phase, and determining the speed of sound in each of the phases of the liquid within a working temperature range. The amplitudes of the vibrations of the pipe along which the multi-phase liquid flows and the frequencies corresponding thereto are determined A range of frequencies with maximum amplitude values is selected. The measured range of frequencies is divided into three parts—the low frequencies corresponding to the gas phase, the mid-frequencies corresponding to the oil phase, the high frequencies corresponding to the water phase. In each of the parts of said frequencies the maximum values of the amplitude are isolated after the use of fast Fourier transforms. Then the volumetric flow rate of each phase of the liquid is calculated on the basis of a given formula.

  • Patent number: 9188471
    Abstract: A sensor system detects the occurrence of two-phase flow by comparing records of fluidelastic force coefficients, which are characteristically different for single-phase and two-phase flows. A baseline of measurements is obtained for a single phase flow, and a baseline of measurements is obtained for a two-phase flow. Measurements of the amplitude and phase of the fluidelastic forces are recorded, and the corresponding fluidelastic force coefficients computed. The fluidelastic force coefficients can be determined for any flow, and compared to the baselines to determine whether the flow is a single-phase or two-phase flow.

  • Patent number: 8984959
    Abstract: A steam quality and flow rate measurement system is described. Embodiments of the system include a steam quality measuring device having a converging/diverging nozzle and ceramic spacer. The steam quality measuring device can be adapted to measure an impedance of a two-phase steam to determine steam quality. The converging/diverging nozzle can be implemented to mix the two-phase flow and reduce pressure loss. The ceramic spacer can be positioned such that steam is in a cross flow when interfacing with the ceramic spacer inside the steam quality measuring device. By placing the spacer in such a position, an electrically conductive liquid phase can be prevented from coating a surface of the ceramic spacer.
