A study of pressure decay in a closed CO2-water system
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Analytical and semi-analytical solutions to the diffusion equation have been obtained in an effort to model pressure decay in a closed CO2-water system. Various boundary conditions that include different physical effects ... -
A study of price determinants of lumber, steel and concrete in Norway.
(Master thesis, 2023)Construction plays a vital role in the economic growth of a society. The cost of building materials constitutes a major share of the total cost of construction projects. It is therefore crucial for the shareholders in the ... -
A study of principal hull parameters for a Spar buoy foundation for a vertical axis wind turbine in the MW-class
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06)This thesis analyses a vertical axis wind turbine (VAWT) in the MW-class used in relation with a floating Spar buoy. The objective was to study the effect of varying principal hull parameters including diameter and draft ... -
A Study of Scale and Scaling Potential during High Salinity and Low Salinity Waterflooding
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Formation damage has been observed to be one of the severe problems during field life operation. In the waterflood projects, proper design water injection at the beginning of field life is crucial to minimize effects of ... -
A study of several proposed alluvial fan deposits in the Kerpini Fault Block, Greece
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-19)The rift in the Gulf of Corinth is one of the most active rifts in the world. Regional N-S extension has caused normal faulting from the Gulf of Corinth and southwards into the Peloponnese Peninsula. The normal faulting ... -
A study of the changes in freeboard, stability and motion response of ships and semi-submersible platforms due to vessel icing
(Master thesis, 2014-06-06)There is an increasing demand for energy in the world, and as the traditional fossil fuel supplies are diminishing, it is pushing the oil and gas industry to seek for natural resources in remote and harsh environments. One ... -
A Study of the Coherences of Turbulent Wind on a Floating Offshore Wind Turbine
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06)In the development of offshore wind turbine industry, the shift from the use of fixed-substructure wind turbines to the floating wind turbines is expected to maximise the offshore wind power extraction while reducing ... -
A study of the diffusion coefficient term in counter current imbibition and its effect on production
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)It is believed that most reservoirs have at least some degree of fractures and spontaneous imbibition is considered to be one of the most important recovery processes in fractured reservoirs. The imbibiton process can be ... -
A Study of the Effect of Pressure and Temperature on the Mechanical Friction of Four Different Fluids Using a Specially Designed Setup
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)The mechanical friction caused by the contact between the rotating drillstring and the borehole or casing can lead to significant challenges such as excessive torque and drag, limitation in running speed of drillstring and ... -
A study of the effect of pumps and desanding cyclones on oil droplets in produced water
(Masteroppgave/UIS-TN-IMN/2009;, Master thesis, 2011)The production of petroleum resources includes co-producing water. This water contains oil products and needs to be treated before discharge to sea or re-injection into the reservoir. The amount of produced water increases ... -
