A study of two-phase gas-liquid flow with viscous oil in a vertical pipe and annuli channel
Bolarinwa, Olusegun Damilare (Master thesis, 2016)The knowledge of gas-liquid flows in annulus geometries can be found in several applications such as the geothermal, nuclear, space, chemical and petroleum. Over time, the design of ducts with annulus geometries for transport ... -
Dynamic two phase flow models for flushing
Rahbari, Ahmadreza (Master thesis, 2014)This thesis aims at modeling the separated liquid-liquid flows with application for flushing. In the beginning, there will be a short review of the governing equations and the fundamental concepts used in this thesis. Two ... -
Experimental study and CFD simulation of water coning phenomenon in perforated geometry
Weberg, Halvor; Stautland, Kristian (Master thesis, 2016)The focus of this thesis is to further examine the water coning phenomenon in annular geometry in a horizontal well completion. This phenomenon is of particular interest to the oil & gas industry, as it may restrict ... -
Experimental study of displacement of viscous oil in pipes by water
Kazemihatami, Milad (Master thesis, 2013)This study is specifically concerned with the understanding of real restart procedure that is very crucial for prediction of oil-water columns displacement after un-expected shut down at water-viscous crude oil transportation. ... -
Experimental study of multiphase flow in an upward-inclined pipe
Kallager, Magnus; Vassmyr, Marit (Master thesis, 2017)This work has been dedicated to gain knowledge about two-phase flow in an inclined pipe through experimental investigation and adaption of theoretical framework from relevant literature. Two-phase flow experiments with ... -
Experimental study on droplet size of dispersed oil-water flow
Khatibi, Milad (Master thesis, 2013)Experimental investigation on droplet sizing measurement techniques both in flow of oil-in-water dispersion and water-in-oil dispersion were performed at the Statoil multiphase flow laboratory in Rotvoll. The focus of these ... -
Modeling of two-phase gas-oil flow in a vertical pipe with viscous oil
Høsser, Eirik (Master thesis, 2014)Most of the physical models that are used for modeling two phase gas oil flows are derived from experiments with less viscous oil. This paper has studied the applicability of these models in commercial codes for flows with ... -
Numerical simulation of surge wave instability of long distance transport of multiphase flow
Dan, Linge (Master thesis, 2018)The surge wave is an unstable flow phenomenon that may occur in the wet gas pipelines. The dramatic decrease in gas flow rate or the stopping of gas production due to other reasons would cause the liquid accumulation at ... -
The Effect of Gas Kinetics on the Gas-Lift Efficiency for Viscous Oil in Vertical Pipe Flow
Steinbakk, Carina Hoddø (Master thesis, 2015)For heavy oil, artificial lift can be applied to increase and stabilise production flow. How the gas kinetics, i.e. the lift-gas composition will influence this increase is the subject of this thesis and will be described ... -
Unstable two phase flow in long vertical pipes
Ravnås, Morten (Master thesis, 2018)Flow instabilities can cause operational problems when transporting multiphase mixtures of oil and gas in offshore risers and pipelines. Several types of flow instabilities have been studied and are well documented. This ...
