Electrical resistance tomography-based multi-modality sensor and drift flux model for measurement of oil–gas–water flow

Abstract This paper proposes a novel method to measure each constituent of an oil–gas–water mixture in water continuous flow, typically encountered many processes. It deploys dual-plane electrical resistance tomography sensor for measuring dispersed phase volume fraction and velocity; gradiomanometer flow density meter drift flux model estimate slip velocities; with absolute pressure temperature measurements. These data are fused rates. Other commonly used operational parameters can be further derived: cut or liquid ratio (WLR) gas (GVF). Trials described rates 5–10 m 3 h ?1 ; oil 2–10 1–15 . The comparative results included published from the Schlumberger Gould Research facility. use configuration measurement flows error ±10% within GVF 9%–85% WLR > 45%.
