Water cut is a vital monitoring and surveillance parameter with great significance in oil production operations and processing. Water-cut measurements are also challenging due to the significant variations and the harsh measurement environment. The objective of this article is to review the current water-cut measurement techniques and suggest future areas that are expanding to overcome existing measurement challenges. Commercially available online methods such as capacitance-based sensors, tomography techniques, gamma densitometry, ultrasonic meters and infrared meters, and the traditional laboratory offline methods, are discussed, along with their principle of operation, detection range, and sensing resolution. Also, the discussed techniques are summarized, highlighting their main advantages and limitations. Furthermore, future trends and research areas, such as Artificial Intelligence (AI), soft computing, Metamaterials, and Nuclear Magnetic Resonance (NMR), which are integrated with water-cut measurements, are briefly mentioned. The current research hotspots are directed toward integrating full-range measurements with multi-parameter detection, high sensitivity, and reliability.

“…Over the past few decades, some techniques have been developed to achieve the accurate measurement of multiphase flow, especially gas-liquid two-phase flow. Some of these techniques, such as radiation attenuation and nuclear magnetic resonance, exhibit satisfactory performance in terms of measurement range and accuracy, and can directly provide mass flowrate, density and composition of multiphase flow 166,167 . Nevertheless, the high cost and system complexity restrict their applicability in the CCUS sector.…”

“…It is therefore very popular to employ this technique in low-cost low-field MR spectrometers. Beyond the two kinds of MR-based methods, O'Neill et al invented an Earth's field magnetic resonance flow meter to measure the velocity probability distribution and T1-velocity probability distribution of multiphase flow [40][41][42].…”

Laminar flow characterization using low-field magnetic resonance techniques

et al. 2021

Laminar flow velocity profiles depend heavily on fluid rheology. Developing methods of laminar flow characterization, based on low-field magnetic resonance (MR), contributes to the widespread industrial application of the MR technique in rheology.In this paper, we designed a low-cost, palm-sized permanent magnet with a 1 H resonance frequency of 20.48 MHz to measure laminar flow. The magnet consists of two disk magnets, which were each tilted at an angle of 1˚ from a starting separation of 1.4 cm to generate a constant gradient, 65 gauss/cm, in the direction of flow.Subsequently, a series of process methods, for MR measurements, were proposed to characterize Newtonian and non-Newtonian fluid flows in a pipe, including phasebased method, magnitude-based method, and velocity spectrum method. The accuracies of the proposed methods were validated by simulations, and experiments of Poiseuille flow and shear-thinning flow on the designed magnet. The new velocity profile methods proposed are advantageous because the MR instrumentation and measurement methods are simple and portable. The sophistication is found in the analysis although the physical principles are straight forward.
