Abstract
Despite intensive research dedicated to multiphase flow measurement in the past decades, accuracy remains one of the key challenges in the oil and gas industry. The Multiphase flow of gas-liquid mixtures has been extensively addressed in the literature. However liquid-liquid flows, are intrinsically more complex and their hydrodynamics are not yet completely understood.
The present study investigates the capabilities of in-line tomography technologies for water cut determination in co-current immiscible liquid-liquid flows. The proposed experimental metering system operates by interrogating the imaging region contained by the pipe walls with a high-frequency alternating electric field. The experiments are conducted on the horizontal section of a flow rig of 100mm in diameter using synthetic oil and saline water as test fluids. Measurements of stratified flows from electric capacitance tomography are contrasted to measurements from an electrical capacitance meter. Measurements enable the computation of water cut in horizontal pipes for diverse flowrates. The results show for the first time the potential of using high frequency non-intrusive electric capacitance meters for oil-water flow measurement.
