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.

Flow Measurement Handbook is a reference for engineers on flow measurement techniques and instruments. It strikes a balance between laboratory ideas and the realities of field experience and provides practical advice on design, operation and performance of flowmeters. It begins with a review of essentials: accuracy, flow, selection and calibration methods. Each chapter is then devoted to a flowmeter class and includes information on design, application installation, calibration and operation. Among the flowmeters discussed are differential pressure devices such as orifice and Venturi, volumetric flowmeters such as positive displacement, turbine, vortex, electromagnetic, magnetic resonance, ultrasonic, acoustic, multiphase flowmeters and mass meters, such as thermal and Coriolis. There are also chapters on probes, verification and remote data access.

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.

Over the last two decades the development, evaluation and use of MFM systems has been a major focus for the Oil & Gas industry worldwide. Since the early 1990's, when the first commercial meters started to appear, there have been around 2,000 field applications of MFM for field allocation, production optimisation and well testing. So far, many alternative metering systems have been developed, but none of them can be referred to as generally applicable or universally accurate. Both established and novel technologies suitable to measure the flow rates of gas, oil and water in a three-phase flow are reviewed and assessed within this book. Those technologies already implemented in the various commercial meters are evaluated in terms of operational and economical advantages or shortcomings from an operator point of view. The lessons learned about the practical reliability, accuracy and use of the available technology is discussed. The book suggests where the research to develop the next generation of MFM devices will be focused in order to meet the as yet unsolved problems. The book provides a critical and independent review of the current status and future trends of MFM, supported by the authors' strong background on multiphase flow and by practical examples. These are based on the authors' direct experience on MFM, gained over many years of research in connection with both operators and service companies. As there are currently no books on the subject of Multiphase Flow Metering for the Oil & Gas industry, this book will fill in the gap and provide a theoretical and practical reference for professionals, academics, and students.* Written by leading scholars and industry experts of international standing* Includes strong coverage of the theoretical background, yet also provides practical examples and current developments* Provides practical reference for professionals, students and academics

The Flow Measurement book comprises different topics. The book is divided in four sections. The first section deals with the basic theories and application in microflows, including all the difficulties that such phenomenon implies. The second section includes topics related to the measurement of biphasic flows, such as separation of different phases to perform its individual measurement and other experimental methods. The third section deals with the development of various experiments and devices for gas flow, principally air and combustible gases. The last section presents 2 chapters on the theory and methods to perform flow measurements indirectly by means on pressure changes, applied on large and small flows.

In previous studies the slotted orifice plate has demonstrated superior performance characteristics to those of the standard orifice plate. In this study, these comparisons are investigated further. The response characteristics of the slotted orifice plate to the standard orifice plate and V-Cone for two-phase flows of water and air at various qualities, flow rates, and pressures are shown visually. The effect of oil as it flows through a slotted orifice plate and standard orifice plate are visually documented. The effect of manufacturing accuracy on the slotted orifice plates is investigated as to the effect on the coefficient of discharge, percent change in pressure, and Reynolds number. The slotted orifice plate mixes two-phase flow better than the standard orifice plate and V-Cone. There is a manufacturing effect on the slotted orifice plates; the larger the area of the slots, the larger the discharge coefficient.
