Imbibition capillary pressure curve modelling for two-phase flow in mixed-wet reservoirs
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Until the early 2000s, the majority of reservoirs worldwide were considered to be either water-wet or oil-wet and capillary pressure correlations were developed subsequently. Recently, it was shown that most reservoirs are ... -
Impact of new petrophysical model to the western flank of Gyda field - understanding of reservoir quality
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)A new petrophysical model on the Gyda field has been developed during 2011 and 2012 by Ian Reid of Petro CTS. This thesis studied the performance of this on three well, and compared it to the old interpretation of the ... -
Impact of Well Configuration on CO2 Injection for Energy Exploitation in Geothermal/Geopressured Reservoirs
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Injecting dissolved CO2 into deep saline aquifers is one of the more promising methods of alleviating greenhouse gas emissions. By simultaneously extracting the geothermally-heated brine in the aquifer, there is an opportunity ... -

Improved Well Design with Risk and Uncertainty Analysis
(PhD thesis UiS;242, Doctoral thesis, 2015-01-16)Uncertainty and associated risk assessment are frequently applied in many disciplines such as engineering, medicine and economics. Yet this study is limited to a quantitative uncertainty analysis with respect to well design, ... -
Improving Reliability of Under Reaming While Drilling Operations by Advancing Understanding in Drilling Dynamics
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Under reaming while drilling operations have become a common practice in the oil and gas industry to address drilling challenges, e.g. reactive and swelling formation, equivalent circulation density (ECD), tight casing ... -
Inclusion of mass transfer terms in the AUSMV transient flow model
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Gas contamination of an oil-based drilling mud while performing drilling operations, having influx of formation gas into the borehole in the form of a gas kick; pose a potential hazard to the personnel, environment and the ... -
