Evaluation of a Flow Simulator for Multiphase Pipelines
Jansen, Jeppe Mathias (Master thesis, 2009)This thesis concerns the terrain slugging capabilities of LedaFlow; it is showed that LedaFlow is indeed able to simulate terrain slugging type 1 and 2 in a S-riser geometry with air and water at atmospheric conditions, ... -
Expansion driven Unstable Two Phase Flows in Long Risers and Wells
Kanu, Elizabeth (Master thesis, 2011)Flow instabilities in long wells and risers under certain flow conditions, is well known. Expansion driven flow instability (EDI) which is relatively little known, refers to occurrence of flow instabilities in long wells ... -
An experimental investigation of multiphase gas-liquid pipe flow at low liquid loading
Chupin, Gaël (Dr.ing;2003:83, Doctoral thesis, 2003)In this thesis, the co-current flow of gas, oil and water in pipes has been studied at low input liquid loading. Despite the frequent occurrence of low liquid loaded gas flow in pipes involved in the production of gas ... -
Experimental investigation of transitional oil-water pipe flow
Schümann, Heiner (Doctoral thesis at NTNU;2016:164, Doctoral thesis, 2016)In this thesis transitional oil-water pipe flow is experimentally studied. Here the word transitional relates to two main topics. First, the study focuses on the investigation of transitional flow patterns and resultant ... -
Experimental investigation on heat extraction from a rock bed heat storage system for high temperature applications
Denis, Okello; Nydal, Ole Jørgen; Nyeinga, Karidewa; Banda, Eldad JK (Peer reviewed; Journal article, 2016)Solar energy is available in an intermittent way, and integrating an energy storage system with solar energy collection devices may promote uninterrupted supply of energy in the absence of the availability of solar energy. ... -
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 dispersed oil-water flow in a horizontal pipe with enhanced inlet mixing, Part 1: Flow patterns, phase distributions and pressure gradients
Schümann, Heiner; Tutkun, Murat; Yang, Zhi Lin; Nydal, Ole Jørgen (Journal article; Peer reviewed, 2016)The study demonstrates how a disturbance of the flow can affect the pressure gradient and further needs a considerable development length to recover. This is of importance for experimental studies as well as industrial ... -
Experimental study of dispersed oil-water flow in a horizontal pipe with enhanced inlet mixing, Part 2: In-situ droplet measurements
Schümann, Heiner; Tutkun, Murat; Nydal, Ole Jørgen (Journal article; Peer reviewed, 2016)Droplet size measurements in premixed oil-water flow are presented. Three traversable focused beam reflectance measurement probes (FBRM) positioned along the test section allowed for measuring averaged droplet size profiles ... -
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 water coning phenomenon in perforated pipes geometry
Shevchenko, Egor (Master thesis, 2013)This Master Thesis is performed in close cooperation between NTNU and Statoil Research Centre in Rotvoll, Trondheim. It focuses on the experimental study of the water coning phenomenon in perforated pipe geometry. This ... -
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 ... -
Experiments and Modelling for the Control of Riser Instabilities: Forsøk og simulering for regulering av ustabil strøm i stigerør
Seim, Jon Egdetveit (Master thesis, 2010)Multiphase flowline-riser systems sometimes encounter fluctuations in flow rate, pressure and liquid hold-up characterized as severe slugging. Slugging is undesirable because the piping and downstream receiving facilities ... -
Experiments on gas flow with wet pipe walls
Arnulf, Thomas (Master thesis, 2013)A new experimental setup, for investigation of a possible pressure drop reduction in gas transport pipelines through indruduction of a liquid film at the pipe walls, is presented. Two experimental series are performed, ... -
Experiments on Surfactant Stabilized Oil-Water Dispersed Flow
Schaefer, Eirik Husum (Master thesis, 2012)This thesis is a study on the behaviour of surfactant stabilized oil-water dispersed flow in horizontal pipes. Water in oil dispersions is a common phenomenon in the oil industry, where oil and water often are produced and ... -
Experiments with a latent heat storage for frying
Geiran, Martin Systad (Master thesis, 2021)Formålet med dette prosjektet har vært å teste et varmelagringssystem kombinert med en stekeplate, som skal brukes til matlaging. Systemet skal varmes med overflødig energi, eller fornybare energikilder på steder uten ... -
Field Development Study of Combined Well Cleanup and Dewatering to Shore on Tanzania Block 2
