▼ The performance of a coupled slotted orifice and swirl
flow meters, and a coupled slotted orifice and an impedance probe
flow meter for
multiphase flow is evaluated to develop a new
multiphase flow meter. The slotted orifice also provides well homogenized
flow for several pipe diameters downstream of the plate. This characteristic provides a homogeneous mixture at the inlet of the swirl
meter, and impedance probe for gas volume fraction measurement (GVF). In order to evaluate the performance of the designed
flow<meters, the GVF and mass
flow rate responses are investigated at varying pressures (20, 40, and 60 psi) and water
flow rates (30, 40, 50, 60, 70, 80, and 90 GPM). The proper correlations are established to provide high accurate two<phase
flow measurement. The new proposed approach provides the GVF measurement with less than 0.017 % error, and the total mass
flow rate measurement within error ?? 0.38 over the range of 4 to 13 lbm/sec.

▼ Multiphase flow is a common
flow when oil and gas are produced from underground, and in the process of hydrocarbon products transportation.
Multiphase flow meters have been one of the most important developments in oil and gas industries. The purpose of inventing a
multiphase flow meter is to measure the
flow rate of a fluid with multiple phases and/or the fraction of different components in the
multiphase fluid.
Electrical impedance measurement is a method that has been recently applied so that a new type of
multiphase flow meter can be developed. Its principle is to record instantaneous measurements of impedance of a
multiphase fluid. After comparing it to the impedance of each component of the fluid, the fractions of each component are known.
One of the limitations of this method is that the
multiphase flow needs to be well homogenized so that the measurement of impedance is accurate and steady. Therefore, in this study a slotted orifice plate is used to homogenize the
multiphase flow.
Venturi meters are commonly used to measure the
flow rate of a fluid. It uses a converging section of pipe to increase the velocity of the
flow which causes pressure drop according to Bernoulli’s theory.
Flow rate can be calculated when the differential pressure is measured.
Flow visualization is a method to get qualitative or quantitative information of a
flow by making the
flow patterns visible.
In this research,
flow rate and gas volume fraction of a water and gas
flow is measures by a slotted orifice plate
flow meter coupled with a Venturi
meter in different orientations. Electrical impedance measurement method is used to obtain the Gas Volume Fraction of the working fluid. Results show that the gains of the signals at 1 MHz frequency have 6th order polynomial correlations with GVF values in both horizontal and vertical orientations, and that phase angles of the signals at 10 MHz frequency have linear correlations with GVF values only in horizontal orientation. The Venturi
meter is used to measure the bulk
flow rates of the working fluid. The Discharge Coefficients of the Venturi
meter is calculated to be 0.97 and 0.89 in horizontal and vertical orientations respectively. In addition, the Discharge Coefficient of the slotted orifice plate is proved to be independent from orientations. At last, a
flow visualization study is conducted to show different
flow patterns as well as the homogenization ability of the slotted orifice plate. Results of the visualization study show that the slotted orifice plate has remarkable ability to homogenize the water-air mixture in all
flow regimes and in both horizontal and vertical orientations.

▼ Depleting oil reserves and fluctuating oil prices have necessitated to increase the efficiency of oil production process. This thesis is focused on developing low-cost sensors, which can increase oil production efficiency through real-time monitoring of oil wells and help in safe transport of oil products from the wells to the refineries. Produced fluid from an oil well is a complex mixture of oil, water and gases, which needs to be quantified for various strategic and operational decisions. For many years, test separators have been used to separate oil, water and gases into three separate streams and then to analyse them individually. However, test separators are being replaced by
multiphase flow meters (MPFM) which can analyse the complex mixture of oil, water and gas without separating it. However, existing MPFMs are either intrusive or require fluid mixing before the sensing stage. In contrast to existing techniques, first part of this thesis presents a microwave sensor, which can measure water fraction in oil in a non-intrusive way without requiring it to be mixed. Gas fraction sensing can also be performed using the same microwave sensor, which is an on-going work. The sensor operates on dielectric measurement principles and comprises a microstrip T-resonator that has been optimized for a 3D pipe surface. Certain locations on an oil field have limited available space, for which we have also presented a compact version of the microwave water-fraction sensor in this thesis. In this version, metallic housing of the sensor has been used to function as a ground plane for the coaxially located spiral resonator. This housing also protects the sensor from environmental effects. In addition to the efficient production of oil, its safe transport is also a concern for the industry. It is physically impossible to inspect a network of thousands of kilometres of pipelines manually. The existing leak detectors suffer from low sensitivity, high false alarms and dependence on environmental effects. In the last part of this thesis, we present a flexible ringresonator based leak detector, which can be clamped at vulnerable locations along the pipeline for early leak detection.

▼ Because of the high cost of many of industry’s current
multiphase flow meters, there is a desire to develop low-cost solutions to the
multiphase flow measurement problem. One such potential solution is an electrical impedance based device placed downstream of a slotted orifice plate.The electrical impedance based part allows one to measure the density, while the slotted orifice plate measures the total volumetric
flow rate. This type of device has been proven effective for NPS 2” piping, but not for larger piping with higher
flow rates and pressures. This thesis describes the design, testing, and evaluation of one such
multiphase flow meter (MPFM) designed for an NPS 6” pipeline carrying an air/water mixture. The MPFM was tested in a closed loop test facility capable of operating at various
flow rates, pressures, and gas volume fractions (GVFs). The test set-up also included a venturi tube
flow meter downstream of the MPFM for additional
flow rate verification.
The electrical impedance portion passes a multi-frequency signal through the fluid between two electrodes diametrically opposed on the pipe. The signal gain across them was measured and shown via analysis of variance (ANOVA) techniques to be correlated to total
flow rate and pressure as well as the GVF of the fluid. The
flow rate correlation had not been seen in smaller diameter pipes using this MPFM concept. A multi-variable regression was applied accordingly, resulting in a calibrated equation that predicted the fluid GVF with an uncertainty of ±5.85% GVF with 95% confidence.
The slotted plate
flow rate data is believed to have been affected partially by the presence of large plastic pieces in its upstream piping, but removing the anomalous data showed an average measurement uncertainty of ±8.80% with 95% confidence. The venturi was capable of predicting the
flow rate with an uncertainty of ±4.53%.
Because of the interdependence of GVF and
flow rate predictions, an iterative technique was used to achieve the accuracies described above. The technique assumes an initial guess for
flow rate and uses that guess in the GVF prediction equation. The GVF prediction is then used in the
flow rate equation to obtain a better
flow rate estimate. This improved
flow rate estimate is then used in the GVF equation, and the process repeats itself until
flow rate and GVF converge on a solution. This technique resulted in total mass
flow rate predictions with an uncertainty of ±6.14%, and GVF predictions with an uncertainty of ±5.85% GVF. These results imply that the electrical impedance-based MPFM concept is applicable to pipes as large as 6”.

▼ Multiphase flow metering is one of the major focuses to develop in oil and gas industries. A combination of slotted orifice plate and electrical impedance technique was investigated in order to provide further development of a new type of
multiphase flow meter.
Flow visualization was conducted in this study to show the performance of the slotted orifice plate to homogenize the mixture
flow and continued with the pattern
flow discussion.
The visualization studied showed that the slotted orifice plate can be applied as a
flow conditioner for two-phase
flow in the pipe in many patterns
flow. An existing pattern
flow map based on the velocity of the each component in the mixture showed that the
flow regime is a volumetric
flow rate and gas volume fraction (GVF) dependant.
Temperature affected the measurement results based on the mixture conductivity behavior. Using a combination of linearization technique and curve fit method, the effect of the temperature to the measurement results can be eliminated for GVF range from 2.5% to 97.5%. The slotted orifice characteristics were then investigated with using the calibration factor, Euler number, and Morrison number with respect to differential pressure and pressure of the mixture
flow.
