“…processing equipment [1][2][3]. Various multi-modality sensors and methods have been reported for multiphase flow measurement such as dual-modality electrical resistance tomography (ERT) and electromagnetic flowmeter (EMF) [1], Venturi meter with blind tee and gamma ray system [4], x-ray tube and group method of data handling [5] and so on.…”

“…Novel methods have recently been proposed for measuring oil-gas-water flows, such as electrical impedance tomography (EIT) in combination with EMF and flow density metering (FDM) in vertical upward flow [7]; combined electrical and ultrasonic sensors in horizontal water-based flow [3] and so on. Such methods measure three-phase flow rate in a safe manner; however, they utilise multiple expensive instruments, resulting in an increased capital and maintenance costs.…”

This paper proposes a novel method to measure each constituent of an oil-gas-water mixture in a water continuous flow, typically encountered in many processes. It deploys a dual-plane electrical resistance tomography sensor for measuring dispersed phase volume fraction and velocity; a gradiomanometer flow density meter and a drift flux model to estimate slip velocities; with absolute pressure and temperature measurements. These data are fused to estimate constituent volume flow rates. Other commonly used operational parameters can be further derived: Water Cut or Water Liquid Ratio and Gas Volume Fraction. Trials are described for flow rates of water 5-10 m3 h-1; oil 2-10 m3 h-1 and gas 1-15 m3 h-1. The comparative results are included with published data from the Schlumberger Gould Research flow facility. The paper proposes the use of the described configuration for measurement of volume flow rates in oil-gas-water flows with an absolute error of ±10 % within Gas Volume Fraction 9 % - 85 % and Water Liquid Ratio > 45 %.

Refineries, fuel depots, airports and storage terminals commonly use fluid level measurement in storage tanks. Different fluid level measurement techniques and devices differ in the inaccuracy of measurement results, costs, and company needs. In addition, these measurements seek reliability of measurement data, immediate response times, control in operations, oil movement, custody transfer and inventory control. The objective is to develop a computer system for measuring fluid levels in oil storage tanks, using ultrasonic and temperature sensors, creating a web application for an automated measurement system (SAM) for managing volumes of Petroleum. The study methodology is i) Analysis of measurement reports. ii) Selection of physical components of the computer system. iii) SAM algorithm design and web application, and iv) Validate the system. The SAM application developed in open source proposes functional modules for administration, control, security, management and monitoring of storage tanks, the status of physical components and generation of dynamic reports in real-time. The results show the control characteristics of storage tanks such as maximum and minimum volume, temperature, time, precise data records in less time than certain current computer structures.

“…Electrical technique has rapid response, however, it is affected by fluid salinity and electrical conductivity. Moreover, electrical methods are difficult to unambiguously distinguish oil, gas and water fluids in oil-gas-water threephase flow, also have limitations related to phase inversion and blending process in oil-water flows [5]. Microwave resonance technique, such as resonant frequency measurement, is ineffective in water-continuous flows.…”

Phase fraction is one of important indexes to characterize multiphase flow. In order to measure each phase fraction of oil-gas-water three-phase flow, liquid level height is detected by Time of Flight – TOF of reflected ultrasound at gas-liquid interface, while oil phase fraction in reflection path is calculated according to the ultrasound attenuation. By studying interactions between multiphase flow and the ultrasound propagation in certain flow patterns, a prediction model for phase fraction measurement of three-phase flow is proposed based on ultrasound transmission attenuation and reflection TOF in the process of horizontal flow with actual phase distributions. Simulation and experimental results under conditions of oil-water two-phase structure with stratified gas in a horizontal pipe show that the proposed method and the established model can accurately detect gas-liquid interface, so that measure oil, gas, water phase fraction. The mechanism prediction model and the measurement device effectively solve the nonlinear response of the ultrasonic measurement parameter, so that can estimate phase fractions of liquids and gas in two-phase as well as three-phase flows simultaneously, which extends the measurement range and the applicable scope of ultrasonic technique to multiphase flow.
