(Master thesis, 2020-05-28) -
Diffusion as an Oil Recovery Mechanism During CO2 Injection in Fractured Reservoirs
(Master thesis, 2013-11-19)This thesis is part of an ongoing study of enhanced oil recovery by CO2 injection in the Reservoir Physics research group at the Department of Physics and Technology (IFT) at the University of Bergen. This work investigates ... -
The effect of calcite minerale on hydrate stability and CO2 adsorption
(Master thesis, 2011-06-01)The background for conducting this study are the huge unused possibilities for storage of large quantities of the greenhouse gas carbon dioxide in old or depleted oil reservoirs or deep brackish aquifers. The method of ... -
Enthalpies of CH4 and CO2 Hydrate Formation and Dissociation Using Residual Thermodynamics
(Master thesis, 2019-11-27)The problem in the processing industries regarding the formation of gas hydrate in pipelines or equipment have inspired much of the research for better understanding of hydrates. The world’s increasing demands for more ... -
Field Pilot Injection Strategies for CO2 Foam EOR in a Layered Heterogeneous Carbonate Reservoir
(Master thesis, 2018-06-20)Injection of CO2 foam for enhanced oil recovery (EOR) may provide economic incentives for large-scale industrial CO2 storage. An international field pilot research program has been initiated to develop and test CO2 foam ... -
Hydrate Formation and CH4 Production from Natural Gas Hydrates - Emphasis on Boundary Conditions and Production Methods
(Master thesis, 2009-05-13)Natural gas hydrate is a solid state of gas and water at low temperature and high pressure. Gas hydrates are known to form hydrate plugs in production line, and has thus generally been considered a problem to the oil ... -
Hydrate formation and CO2 - CH4 exchange in sandstone - An experimental study with emphasis on the role of initial brine saturation and salinity
(Master thesis, 2013-06-01)Recent research activity has demonstrated the viability of producing methane from gas hydrate bearing sediments by injecting and sequestering CO2 in a process where CO2 replace methane in gas hydrate by a process called ... -
Modelling substances present in an amine scrubbing plant during CO2 capture with aqueous monoethanolamines using multivariate data analysis and ATR-FTIR spectroscopy
(Master thesis, 2018-06-20)Since the 19th century, an increase in the earth’s temperature has been recorded. The rise in temperature is caused mainly by anthropogenic greenhouse gases, such as CO2. Industrial processes are the cause of 40% of the ... -
New Concept for Evaluating the Risk of Hydrate Formation during Processing and Transport of Hydrocarbons
(Master thesis, 2017-10-31)Transport of hydrocarbons from reservoir to gas processing plants and for supply to delivery terminals is predominantly done using pipelines, particularly within reasonable distance. In the North Sea of Norway, there are ... -
A numerical study of transport and spreading of gases from natural analogues of gas-seepage through the seafloor
(Peer reviewed; Journal article, 2009-02)Natural leakages of CO2 are reported in the literature at mid ocean ridges and CH4 seepages in hydrocarbon rich ares. These could potentially serve as natural analogues of leakages from CO2 storages. In this study we have ... -

(Master thesis, 2008-06-02)Bakgrunnen for denne oppgaven er et samarbeidsprosjekt mellom Institutt for Energiteknikk(IFE), Christian Michelsen Research (CMR) og Prototech. Prosjektet heter Zero Emission Gas Power Project, ZEG. Prosjektet innebærer ... -
Quantitative Pore-Scale Analysis of CO2 Foam for CCUS
(Master thesis, 2019-12)This experimental thesis is a part of ongoing projects lead by the Reservoir Physics group at the Department of Physics and Technology, University of Bergen. The main objectives of this thesis were to develop image analysis ... -
A statistical gap-filling method to interpolate global monthly surface ocean carbon dioxide data
(Peer reviewed; Journal article, 2015-10-24)We have developed a statistical gap-filling method adapted to the specific coverage and properties of observed fugacity of surface ocean CO2 (fCO2). We have used this method to interpolate the Surface Ocean CO2 Atlas (SOCAT) ... -
Study of Gas Mobility Control during CO2 Injection for Enhanced Oil Recovery
(Master thesis, 2016-06-01)Carbon Dioxide (CO2) has been used as a commercial source for Enhanced Oil Recovery (EOR) for over 40 years. In recent years, the utilization of anthropogenic CO2 has become more attractive, because of its proven EOR and ... -
