Study on oil–water two-phase flow in horizontal pipelines

Journal of Petroleum Science and Engineering, 2007
Abstract The simultaneous flow of oil and water in pipelines is a common occurrence in the petroleum industry. Water fractions in the output stream increase materially during the producing life of a well and many wells exist from which economic production can still persist with water volume fractions in the liquid phase in excess of 90%. The presence

Ultrasound attenuation characteristics in oil-water two-phase flow

2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015
Accurate measurement of multiphase flow parameter has significance on the optimization of production process and equipment. Ultrasonic measurement technology has potential applications in two-phase flow measurement. In order to understand the ultrasonic testing mechanism, the ultrasound attenuation characteristics in the oil-water two-phase flow are ...

Stratified Oil-Water Two-Phases Flow of Subsea Pipeline

The Journal of Ocean, Mechanical and Aerospace -science and engineering- (JOMAse), 2014
Oil-water two-phase flow in 0.0254m horizontal pipe is simulated using FLUENT 6.2. The stratified flow regime is modeled using Volume of Fluid (VOF) with turbulent model RNG k-?. Grid independent study has been conducted to decide mesh size for solution accuracy and optimum computational cost.

Experimental Studies on the Measurement of Oil-water Two-phase Flow

AIP Conference Proceedings, 2007
Oil‐water two‐phase flow measurement was investigated with a Venturi meter and double‐U Coriolis meter in this work. Based on the Venturi differential pressure and the quality of two‐phase flow, a model for measuring oil‐water mass flow rate was developed, in which fluid asymmetry of oil‐water two‐phase flow was considered.

Oil-Water Two-Phase Flows in Large-Diameter Pipelines

Journal of Energy Resources Technology, 2001
Two-phase oil-water flows in a 10-cm-dia horizontal pipe have been experimentally investigated to study the effect of surfactant on oil-water distributions. Results show that at input water cut of 20 percent and lower, the water layer velocity is lower than mixed layer velocity up to an input mixture velocity of 1.6 m/s.

Two-Phase Flows (Oil/Water): Flow Regimes and Wetting

2002
We report experimental investigations on the flow regimes obtained in a two-phase flow of two immiscible fluids in a micro-channel. It is shown that the wetting properties crucially control the regimes: when one phase completely wets channel walls, ordered patterns are obtained, while, disordered patterns are produced when wetting is partial.
