A New Method for Measuring Water Holdup of Oil-Water Two-Phase Flow in Horizontal Wells
Processes, 2022 The production profile logging technology of Oil-water two-phase flow is an important support technology for efficient development of horizontal oil wells. Moreover, the water holdup of Oil-water two-phase flow is one of the important dynamic measurement parameters for production profile logging technology.

Simple microwave method for detecting water holdup [PDF]
Microwave and Optical Technology Letters, 2007 AbstractA microwave sensor is designed to measure the resonance behavior of the hydrocarbon mixture to determine the water holdup of a near horizontal oil carrying pipeline. This technique is particularly useful for detecting very small water holdup (<5%) as demonstrated by simulated and experimental results. © 2007 Wiley Periodicals, Inc. Microwave

Influence of Oil and Water Holdup on Mixture Velocity in Horizontal Flows [PDF]
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2008 Usage of a traversing beam gamma densitometer measurement for the phase fractions distribution of a mixture of water and kerosene was achieved experimentally in a horizontal pipe tube. The phase fractions distribution was determined with the beam being traversed in three directions for example 0, 45 and 90° of the vertical line passing through the axis
