... 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 This study provides horizontal pipe pressure drop and liquid holdup measurements for three-phase flow of sand, viscous oil and gas with a focus on slug flow. We developed a correlation for predicting the liquid holdup and dimensionless pressure gradient in the presence of solids during...

...) proposed the following relationship for horizontal pipes, (3) v d = 0.542 g D . Benjamin calculated the value of the drift velocity coefficient by using inviscid (potential) flow theory (surface tension and viscosity are neglected). The drift velocity in horizontal slug flow...

... 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...

... 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...
