Laboratory evaluation of sodium silicate for zonal isolation
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)A common problem for maturing oil fields is excessive water production. Ultimate oil recovery could be increased considerably by implementing an appropriate water production management. Solutions for managing excess water ... -
A laboratory scale approach to wettability restoration in chalk core samples
(Peer reviewed; Journal article, 2019)Wettability in chalk has been studied comprehensively to understand fluid flow mechanisms impacting coreflooding experiments. Wettability becomes paramount in understanding the parameters influencing chalk-fluid interactions. ... -
Lack of Association Between GBA Mutations and Motor Complications in European and American Parkinson's Disease Cohorts
(Peer reviewed; Journal article, 2021)Background: Motor complications are a consequence of the chronic dopaminergic treatment of Parkinson’s disease (PD) and include levodopa-induced dyskinesia (LIDs) and motor fluctuations (MF). Currently, evidence is on ... -
Landkraft til havs: Hvem er det som spør?
(Journal article; Peer reviewed, 2012-06)Elektrifisering vil si å erstatte gass-generatorer til drift av petroleumsvirksomhet med kraft fra land. Problemstillingen belyses i artikkelen fra et bedriftsøkonomisk og et samfunnsøkonomisk perspektiv ved hjelp av to ... -
Large Eddy Simulation of buoyant plumes
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)Industrial and environmental safety relies on understanding and evaluating risks and failures on the individual processes and operations. Simulating hazardous fluid flows with the use of Computational Fluid Dynamics (CFD) ... -
Large Eddy simulations of flow around tandem circular cylinders in the vicinity of a plane wall
(Peer reviewed; Journal article, 2018)In order to investigate the three-dimensional flow around free-spanning, tandem marine pipelines, Large Eddy Simulations (LES) with Smagorinsky subgrid scale model are performed using the open-source code OpenFOAM. Two ... -
Large eddy simulations of flow past an inclined circular cylinder: Insights into the three-dimensional effect
(Peer reviewed; Journal article, 2023)The flow past an inclined cylinder is simulated using large eddy simulations to study the three-dimensional wake flow effects on the forces on the cylinder at Re = 3900. Four inclination angles of α = 0°, 30°, 45°, and 60° ... -
Large Time Step schemes for Hyperbolic Conservation Laws in 2 Space Dimensions
(Master thesis, 2022)Numerical solutions to partial differential equations (PDEs) will create varying amounts of error depending on different factors such as the numerical scheme and how fine the grid size is. In this thesis, we explored two ... -
Late life field material balance analysis – Statfjord Fm.
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2012)Recently, it has become apparent that the prediction of the Statfjord reservoir potential determined from the ECLIPSE simulator differs from the actual formation performance, i.e. simulated fluid production results are too ... -
Late Paleozoic development of the Finnmark Platform, southwestern Barents Sea, Norway
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-12)Following the recent Gohta and Alta discoveries in the Loppa High by Lundin Norway AS in 2013 and 2014 respectively, there has been an enhanced interest for the Upper Paleozoic succession in the Norwegian Arctic Shelf ... -
