multiphase flow meter working principle

If homogeneity of flow can be achieved, then three instruments are required each measuring a characteristic of the mixed fluid flow. Handbook of Multiphase Flow Metering Page 1 of 113 Preface Multiphase metering, and a handbook for providing the users, manufacturers and others some form of guidelines for handling multiphase flow measurement has been wanted by the industry from the start. With co-mingled flow from oil zones with differing PVT response, and different water salinities and hence densities, this PVT uncertainty may be the largest source of error in the measurement. Nevertheless, it is still widely recognised that no single MPFM on the market can meet all multiphase metering requirements.Unconventional Solutions - SONAR Multiphase MeasurementUnconventional Solutions - SONAR Multiphase MeasurementDepartment of Trade and Industry (UK), ‘Guidance Notes for Petroleum Measurement’, Issue 7, December 2003, pp.

The meter is based on the isokinetic sampling method: this principle involves the sampling of a small part of the multiphase flow; the sampled mixture is then separated Depleting oil reserves, (More water and gas in the produced oil) along with smaller, deeper wells with higher water contents, saw the advent of increasingly frequent occurrences of multiphase flow where the single-phase meters were unable to provide accurate answers. 1.2 Principles of Measurement And Technologies of Multiphase flow meter (MPFM) A multiphase flow meter measures the velocity of each phase, i.e. Industry experts have forecast that MPFMs will become feasible on an installation per well basis when their capital cost falls to around US$40,000 – US$60,000. MSV's are particularly suitable for onshore pad drilling, and where many nearby wells have similar pressures, and allow MPFM's to be shared between groups of wells.

It also measures the cross-section occupied by each phase. Since oil, gas and water all contain hydrogen atoms, multiphase flow can be measured using magnetic resonance. The Norwegian Society for Oil and Gas Measurement (NFOGM) first developed a handbook to serve as a guideline and provide a common …

Multiphase Flow meter Principle. The introduction of the multi port selector valve (MSV) also facilitated the automation of the use of MPFM's, but this can also be achieved with conventional valving designs for well tests. In some cases, an ap… Multiphase Flow Meters (MPFM) are flow meters that can measure the flow of multiphase fluids (e.g.

The meter measures the flow rates at line pressures, which are typically orders of magnitude greater than atmospheric pressure, but the meter must report the oil and gas volumes at standard (atmospheric) pressure and temperature. However, Possible to get Radio active source type multiphase flow meters of slamburger make, working principle.We are looking for mass flow meters for measuring the out put of our ASU.The product is LIQUID OXYGEN LIQUID NITROGEN AND LIQUID ARGON. The difference in magnetic resonance properties allows making a distinction between the flowrates of oil, gas and water.This measurement principle also forms the basis of magnetic resonance based Multiphase Flow Meters (MPFM)s are recognized to provide a number of additional benefits to O&G production:MPFM can be employed to reconcile oil, gas and water measurement at all entry and exit points of a production network, minimizing potential serious economic consequences in terms of taxes and when a single processing facility is shared by different producers, MPFMs can be used to meter the production from each license owner;Multiphase flowmeters are able to deliver real-time, continuous data concerning production of the different phases; therefore they can be very useful for reservoir management and for optimization of the production;The continuous measurement from MPFMs provide further information to detect potential issues in the production system.Multiphase streams are typical of the O&G fields, since the producing wells normally generate mixture of liquid and gaseous hydrocarbons with a variable quantity of water. VO, VG, VW velocity of oil, gas and water respectively. As the initial interest in multiphase flow metering came from the offshore industry, most of the multiphase metering activity was concentrated in the Most modern meters combine a venturi flow rate meter, with a gamma densitometer, and some meters have additional measurements for water salinity. The largest Coriolis flow meter that is currently available has a maximum flow rating of 25,000 lb/min (11,340 kg/min), and is equipped with 6 in. Much of the early research was done at the Christian Michelsen research center in Bergen, Norway,A number of factors have instigated the recent rapid uptake of multiphase measurement technology: improved meter performances, decreases in meter costs, more compact meters enabling deployment of mobile systems, the need for sub sea metering, increases in oil prices and a wider assortment of operators. The meter must thus know the Pressure / Volume / Temperature properties of the oil, to add to the measured gas rate at line pressure the additional gas that would be liberated from the oil at atmospheric pressure, and also know the loss in oil volume from the release of that gas in conversion to standard conditions. Knowing single rates of gas liquid and water is crucial for the production industry in order to monitor the reservoir, to improve the well performances and to optimize the production.The traditional solution is represented by the test separators, large vessels where the different phases are divided and then measured through standard singlephase techniques. Multiphase Flow Meters (MPFM) are devices used to measure the individual oil, water and gas flow rates in a multiphase flow.

Since oil, gas and water all contain hydrogen atoms, multiphase flow can be measured using magnetic resonance.For this purpose the fluids are magnetised and subsequently excited by radio frequency pulses. Sub Sea meters typically use conventional sub sea valve designs, to ensure maintainability.
