... et al., 2012). A study by Zhao et al. (2015 ) investigated viscous oil and gas slug flow characteristics and proposed correlations to predict slug flow parameters such as slug length and holdup ( Al-Safran et al., 2013 , Yang et al. 2015 ). Abstract This study provides horizontal pipe...

... Abstract An experimental study is conducted in a 6-in. inner diameter (ID) high-pressure facility to investigate the pressure effects on two-phase oil-gas low-liquid-loading flow in horizontal pipes. The investigated flow characteristics include pressure gradient and liquid holdup. Total...

... Abstract Three-phase gas-oil-water experiments have been conducted in horizontal pipes at various flow rates and water cuts. Three-phase flow patterns have been observed and identified using a high speed video system and a new classification of three-phase flow patterns is proposed. Twelve new...

.... The experiments are performed on a flow loop with a test section of 50.8-mm ID and 18.9-m long horizontal pipe. Superficial liquid and gas velocities vary from 0.01 to 1.75 m/s and from 0.1 to 20 m/s, respectively. Oil viscosities from 0.181 to 0.587 Pa·s are investigated. The experimental results are used...

... ABSTRACT A pipe viscometer facility was constructed to investigate the flow of oil-water dispersions in horizontal pipes. Pressure drop, liquid mass flow rate, mixture temperature, input water fraction, and mixing intensity data were obtained for 490 oil-water tests. Mixture velocities ranged...

.... Correlations for predicting two-phase friction factors for horizontal pipe flow have been published by many authors. All published correlations are based on experimental data, and no previous attempts have been made to compare these correlations. Published equations for predicting two-phase flowing pressure...
