“…The inductive transducer produces small changes in inductance which vary linearly with the process variable, but their measurement is very difficult by the conventional Maxwell bridge. Ma et al [17] have provided a novel concept for non-intrusive measurement of continuous water flow in multiphase flows by combining magnetic induction tomography (MIT) and electromagnetic velocity tomography (EVT). MIT is used for measuring the cross-sectional volumetric fraction whereas EVT is used for the measurement of local axial velocity.…”

“…Since the measurements are based on the electrical conductivity and the magnetic permeability of the medium, it will require a high excitation frequency to increase the signal from the sensor [99]. In a recent research [100] a combination of magnetic induction tomography (MIT) and electromagnetic velocity tomography (EVT) showed promising results in measuring the velocity of the continuous phase (water) in a two-phase flow consisting of oil and water. MIT and EVT are both types of electromagnetic tomography techniques.…”

Multi-phase flow meters are of huge importance to the offshore oil and gas industry. Unreliable measurements can lead to many disadvantages and even wrong decision-making. It is especially important for mature reservoirs as the gas volume fraction and water cut is increasing during the lifetime of a well. Hence, it is essential to accurately monitor the multi-phase flow of oil, water and gas inside the transportation pipelines. The objective of this review paper is to present the current trends and technologies within multi-phase flow measurements and to introduce the most promising methods based on parameters such as accuracy, footprint, safety, maintenance and calibration. Typical meters, such as tomography, gamma densitometry and virtual flow meters are described and compared based on their performance with respect to multi-phase flow measurements. Both experimental prototypes and commercial solutions are presented and evaluated. For a non-intrusive, non-invasive and inexpensive meter solution, this review paper predicts a progress for virtual flow meters in the near future. The application of multi-phase flows meters are expected to further expand in the future as fields are maturing, thus, efficient utilization of existing fields are in focus, to decide if a field is still financially profitable.

“…saline water, and one non-conductive phase, like gas or oil. These work include the imaging of conductivity contrast by using static phantom setup [6], semi-static experimental verification [7], and water continuous two phase flow experiments [8]. In the present study, the former two approaches are used to demonstrate the feasibility of broadening the niche of electrometric induced systems for measurement of multiphase flows containing not only water and hydrocarbons but also inorganic particles like sand.…”

Electromagnetic metering offers significant promise in the measurement of low-conductivity medium like in multiphase flow. Such measurements rely on the measurement of conductivity contrasts formed by two medium of substances, one substance being conductive and the other being non-conductive. In these conditions, it is assumed that the permittivity-induced displacement current is small compared to eddy current induced by conductivity, therefore the displacement current is usually ignored. The present study demonstrates, through solution of the electromagnetic forward problem and pilot tests, that the temporal, spatial and frequency related permittivity and conductivity changes are all captured by the induced electrical voltage measurement. Permittivity reflects in the amplitude and the conductivity reflects both in the amplitude and the phase angle of the voltage. The weight of each parameter to the voltage measurement is studied here. The findings of the study disclose that an electromagnetic metering system may offer advantages in continuously monitoring and measuring hydrocarbon contents and solid concentrations via both the amplitude and phase shift changes.
