Simulation of fracture slip and propagation in hydraulic stimulation of geothermal reservoirs
(Doctoral thesis, 2023-09-01)Rollen til hydraulisk stimulering i å øke produksjonen fra geotermiske reservoarer, og muliggjøre kommersiell utnyttelse av et større spekter av geotermiske ressurser, har fått økt oppmerksomhet de siste tiårene. Under ... -
Simulation of geomechanical effects of CO2 injection in cold aquifers with possibility of hydrate formation
(Chapter; Peer reviewed, 2011)The injection of CO2 in saline aquifers can have a significant impact on the geochemistry and the geo-mechanics of the reservoirs. Due to this injection, minerals will dissociate in regions with low pH or precipitate in ... -
Simulation of hydrate dynamics in reservoirs
(Chapter; Peer reviewed, 2011)Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon dioxide ... -
Simulation of injection-induced deformation for a stimulation experiment at the Grimsel underground laboratory
(Master thesis, 2020-11-06)Numerical models have increasingly become important tools to complement planning, testing, and implementation of technologies and strategies for geothermal reservoir projects in basement and crystalline igneous rock. Access ... -
Simulation of Nanoparticle-Stabilized CO2-Foam in Sandstone

Simulation of prompt gamma production in particle therapy and beam trajectory imaging
(Master thesis, 2015-06-01)In cancer oncology, using of Mega electron Volt (MeV) bremsstrahlung photons has been clinically practised on cancer patients since photons can deliver a significant dose to tumour volumes when projected into the body in ... -
Simulation of Reactive Transport in Fractured Porous Media
(Journal article; Peer reviewed, 2023)Numerical simulations of reactive transport in fractured porous media require the solution of coupled physical and chemical processes that depend on the fractures. Such coupled processes are described by a system of nonlinear ... -
Simulation of seismic attributes for earth models with different continuity properties
(Master thesis, 2019-11-21)The combination of kinematic and dynamic ray tracing has been used since the 1970s for simulation (modelling) of seismic energy in the subsurface. Kinematic/dynamic ray tracing is used to simulate the travel time, amplitude ... -
Simulation of the Eemian Greenland ice sheet
(Doctoral thesis, 2019-03-05)This thesis focuses on the simulation of the Greenland ice sheet (GrIS) during the Eemian interglacial period (~125,000 years ago). The warm Eemian summers on Greenland are used as a past analogue for future warmer conditions. ... -
Simulation of viscous instabilities in miscible and immiscible displacement
(Master thesis, 2008-06-09)This study includes modeling of viscous instabilities at both miscible and immiscible displacement. Oil recovery of heavy oil leads to unstable displacement for adverse mobility ratio for both miscible and immiscible ... -
Simulation Studies of Hybrid EOR
(Master thesis, 2019-06-22)Injection of low salinity brine in combination with surfactant and polymer for enhanced oil recovery (EOR) have been proven to substantially increase oil recovery. Large EOR potential exists on the biggest fields on the ... -
A Simulation Study of Goodness-of-Fit Tests for Binary Regression with Applications to Norwegian Intensive Care Registry Data
(Master thesis, 2019-01-31)When using statistical methods to fit a model, the consensus is that it is possible to represent a complex reality in the form of a simpler model. It is helpful to systematically measure a model’s ability to capture the ... -
Simulation Study of In-Situ Polymer Rheology in a Radial Flow Experiment
(Master thesis, 2018-06-27)The global energy demand is continuously growing, and even though renewable energy sources are becoming increasingly important, oil remains the leading energy fuel to this date, accounting for one third of the consumption. ... -
Simulation Study of Polymer Injectivity and Rheology in Radial Models
(Master thesis, 2017-08-02)The simulation study conducted in this thesis was carried out at the Centre for Integrated Petroleum Research (Uni CIPR) at the University of Bergen (UiB). The main objective in this thesis was to study polymer rheology ... -
A simulation workflow for large-scale CO2 storage in the Norwegian North Sea
(Journal article, 2016-06)Large-scale CO2 injection problems have revived the interest in simple models, like percolation and vertically-averaged models, for simulating fluid flow in reservoirs and aquifers. A series of such models have been collected ... -
Simulation-based assessment of cholera epidemic response: A case study of Al-Hudaydah, Yemen
(Journal article; Peer reviewed, 2023)Cholera kills between 21,000 and 143,000 people globally each year. It is often fatal, killing up to 50% of the severely symptomatic patients; but death by cholera is preventable with timely treatment, so that the fatality ... -
