Book excerpt: 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

Book excerpt: The oil and gas industry's goal of developing high performing multiphase flow metering systems capable of reducing costs in the exploitation of marginal oil and gas reserves, especially in remote environments, cannot be over emphasised. Development of a cost-effective multiphase flow meter to determine the individual phase flow rates of oil, water and gas was experimentally investigated by means of low cost, simple and non-intrusive commercially available sensors. Features from absolute pressure, differential pressure (axial), gamma densitometer, conductivity and capacitance meters, in combination with pattern recognition techniques were used to detect shifts in flow conditions, such as flow structure, pressure and salinity changes and measured multiphase flow parameters simultaneously without the need for preconditioning or prior knowledge of either phase. The experiments were carried out at the National Engineering Laboratory (NEL) Multiphase facility. Data was sampled at 250 Hz across a wide spectrum of flow conditions. Fluids used were nitrogen gas, oil (Forties and Beryl crude oil - D80, 33o API gravity) and water (salinity levels of 50 and 100 g/l MgSO4). The sensor spool piece was horizontally mounted on a 4-inch (102mm) pipe, and the database was obtained from two different locations on the flow loop. The ability to learn from 'experience' is a feature of neural networks. The use of neural networks allows re-calibration of the measuring system on line through a retraining process when new information becomes available. Some benefits and capabilities of intelligent multiphase flow systems include: · Reduction in the physical size of installations. · Sensor fusion by merging the operating envelopes of different sensors employed provided even better results. · Monitoring of flow conditions, not just flow rate but also composition of components. · Using conventional sensors within the system will present the industry with a much lower cost multiphase meter, and.

This book was released on 2012-12-06 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: A IUTAM symposium on "Measuring Techniques in Gas-Liquid Two Phase Flows" was held on July 5-8, 1983 in Nancy, France. This topic in cluded instrumentation for steam-water and liquid-vapor flows but strictly excluded measuring techniques for gas or liquid flows with solid particles. The top priority in the paper selection was given to presentations of new methods which had been substantiated by theoretical modeling, calibration tests and comparison tests with other techniques. Examples of experimental resul ts obtained with the proposed instrumentation had to be displayed. However the interpretation of these results in terms of two-phase flow or heat transfer modeling did not fall wi thin the scope of the meeting. Thirty four papers were presented during the Symposium and 79 participants coming from Canada, European countries, Japan and the United States attended the sessions. They represented not only Universities but also state agencies and private companies. After the meeting each paper was peer-reviewed by at least three referees.

Download or read book Development of a Multiphase Composition Measurement Method by Using Capacitive Sensor Array written by Javier Ortiz Castro and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase flow, a flow of two or more liquid/gas components, is present in many industries. One of the challenges is to measure accurately the volumetric/mass ratio of each component against the total volume/mass. In the oil and gas industry, this kind of measurement is performed on a regular basis. Since the early 1980s, many methods have been proposed for multiphase flow measurement and some are commercially available today. However, these sensors often depend on a separator to isolate each phase, or use a homogenizer/mixer to achieve consistent solutions, or employ Gamma- Ray radiation provided by a nuclear source. The approach used in this research is to combine a sensor with an integrated cyclonic stratifier that transforms diverse flow regimes of multiphase flow into a channel flow regime. The sensor employs a relatively simple capacitive sensor array and allows for accurate measurements of phase fractions in real time. The system is also capable of compensating for drift in parameters such as permittivity, often caused by a changed chemical composition, e.g. the level of sulphur in the oil, the salinity of water, or due to variable temperature.

This book was released on 2002 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase flow measurement has become an important topic for research due to the needs of users in various applications. Present systems are seen to have limitations in their measurement accuracy. This research presents a new approach to multiphase flow measurement by using signal analysis techniques to recover additional information from the unconditioned signals from conventional single-phase flowmeters. High frequency fluctuations embedded in sensor signals, which are treated as "noise" in conventional techniques of measurement, are extracted and analysed. The raw signals from different flowmeters are conditioned to obtain the high frequency signal components, and subjected to signal analysis using mainly the Fourier transform and power spectrum density function. The system uses electronic circuits for data acquisition, signal conditioning, and data processing. Neural networks are employed to yield the measurement information. Statistical parameters and extracted features from the high frequency signal are used as inputs to the neural networks. The outputs from the networks give separate values for the air and water flow rates within the two-phase flow without additional measurement from other instruments. Four different types of flowmeter, namely the orifice plate/differential pressure flowmeter, the electromagnetic flowmeter, the turbine flowmeter, and the vortex flowmeter were tested under two-phase flow conditions (air in water) in a laboratory flow rig at low pressure (less than 2.5 bar). A density meter based on a resonant sensor was also included in the tests. The results from neural networks show excellent ability at estimating and predicting individual phase flow rates in two-phase flow. The major advantage of this approach is that it uses the raw signal from the conventional sensors of standard flowmeters to implement the measurement, without needing further measurements from other sensors. Moreover, test laboratory results show that measurement accuracy to within ±2% is possible, especially using the vortex flowmeter.

Available in PDF, EPUB and Kindle. Book excerpt: This extensively research book assembles a tremendous amount of practical information on Multi-phase flow in oil and gas production wells and pipelines. The book summarizes those fundamental concepts with relevance to a broad spectrum of multiphase flows. This book is organized as follows.Chapter 2 gives an overview of multiphase flows looking at the flow regimes that are generally used, trends in multiphase flow modelling. Chapter 3 gives a detailed overview of the physical model of wellbore flow used. The concept of drift flux is briefly discussed. Methods used to the solve model equations numerically are discussed in Chapter 4. It is shown that the traditional central schemes are unable to capture properly the physics of the flow. For the complex flow systems, which include several non-linear coupled differential equations, a new computation algorithm is proposed. First, a Jacobian splitting must be applied accounting for different directions of the propagation of information. In Chapter 5 an assessment is performed of the impact of the chosen time-integration scheme on results of data assimilation based on the extended Kalman filter approach and also discusses the use of the implicit Euler scheme. Chapter 6 starts from analysis of the transient pressure signal generated in the wellbore due to inflow from the reservoir. The possibilities of indirect multiphase flow metering are then discussed. Finally, the method, which was limited to a rapid inflow scenario, is extended in Chapter 7 to a gas coning control application, in which the relevant quantities are estimated from multiple pressure measurements and single multiphase flow measurement at the outflow. The performance of both techniques proposed is evaluated using a series of simulation based test cases and measurements generated by the OLGA simulator. This book is targeted at final year students, graduate students and researchers at the cutting edge of investigations into the fundamental nature of multiphase flows; it is intended as a reference book for the basic methods used in the treatment of multiphase flows.
