An Introduction to Supersymmetry
(Masteroppgave/UIS-TN-IMF/2019;, Master thesis, 2019-06-14)This thesis gives an introduction to supersymmetry. We compute the Poincaré- conformal- and Clifford algebra in any dimension. Most examples are in four dimensions, including the Wess-Zumino model and supersymmetric gauge ... -
An Introduction to the Welltec Annular Barrier and its Interaction with the Open Hole Formation
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Developments in drilling have opened for the construction of extended reach wells. They can have large intermediate and reservoir sections, which may need zonal isolation. To isolate the different zones, Welltec has developed ... -
An investigation into the heat transfer process in petroleum wells, and a comprehensive modeling study investigating the temperature distribution in production wells
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)When producing hot fluid from a reservoir, the production well experiences changing temperatures with depth for the different tubing, casing, cement and wellbore interfaces. To what extent the temperatures change is depending ... -
An investigation of permeability and porosity evolution of Kansas chalk under in-situ conditions
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013)Injections of brine into the chalk can leads to compaction. The chemical impacts of water injection on the mechanical strength of chalk have been investigating for several years. Also, porosity and permeability evolution ... -
An optimization study of current drill bit technology for the Troll Field, Norway
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In the current study geology, drill bit technology and drilling challenges at the Troll Field are mapped. It has been established that the Troll Reservoir Formation consists of unconsolidated shallow marine sandstone ... -
An Overview and Discussion of MPD Systems used in Offshore Operations
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Globally, established fields are reaching maturity and easily accessible reserves have already been exploited. The remaining reserves are generally more difficult to drill and attempting to drill them using conventional ... -

Anaerobic Co-digestion of Aquaculture and Municipal Waste
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)This study describes anaerobic co-digestion of aquaculture waste from Fister Smolt and municipal waste from IVAR SNJ. Both waste types are in rapid increase worldwide, yet production of biogas has mainly considered municipal ... -
Anaerobic Conversion of Glycol Rich Industrial Wastewater to BiogasAnaerobic Conversion of Glycol Rich Industrial Wastewater to Biogas
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Oil and gas industries generate large volumes of wastewater during exploitation and processing of oil and gas. Industrial wastewater contains glycols along with other organic and inorganic compounds. It is essential to ... -
Anaerobic Fungi: Past, Present, and Future
(Peer reviewed; Journal article, 2020-10)Anaerobic fungi (AF) play an essential role in feed conversion due to their potent fiber degrading enzymes and invasive growth. Much has been learned about this unusual fungal phylum since the paradigm shifting work of ... -
Anaerobic treatment of glycol contaminated wastewater for methane production
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Glycols are usually used in the offshore gas industry as hydrate inhibitor in gas pipelines laid deep under the sea. Glycols, in its use, are contaminated by dissolved salts from formation water together with scaling and ... -
