Adsorption of silica nanoparticles in chalk and sandstone and it effect of fluid/rock interactions.
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)This study addresses the adsorption of Silica nanoparticles (NPs) and its effect on fluid/rock interactions in chalk and sandstone reservoirs. The first part of this thesis addresses the kinetic adsorption behaviour of ... -
Alternative applications of wired drill pipe in drilling and well operations
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)Oil and gas companies target to carry out drilling and other well operations in a safe and cost-effective manner with focus on the long-term integrity of the wells. Well operations become more challenging in environments ... -
An experimental study of unsupported pipe buckling in live well intervention
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)In this experimental study, unsupported pipe experiments are conducted. Information regarding intervention operation, focusing on snubbing operations in live well interventions and unsupported buckling during these operations, ... -
Analysis of pore pressure measurements in exploration wells in the Norwegian North Sea
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-12)The aim of this thesis was to examine the pore pressure measurements in the Norwegian North Sea. To study the possibility of the overpressure being an indicator that can increase the probability of hydrocarbon discoveries ... -
Aqueous Electrochemical Reduction of Carbon Dioxide using Carbon Supported Copper Electrocatalyst
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-07-10)The atmospheric concentration of CO2 has been rising progressively from 280 parts per million (ppm) in the pre-industrial time to 410 ppm in 2018. The anthropogenic CO2 emissions are dominated by fossil fuel sources, which ... -
Availability and Quality of Drilling Data in the Volve Dataset
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)The importance of data sharing cannot be overexaggerated today, when the recent trend toward automation fundamentally reshapes the way of how operations are done in the oil industry. The emergence of real-time trend analysis ... -
Blowout Flow Rate Modelling
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)A blowout represent one of the major concerns associated with drilling, completion, maintenance and production of an oil field. Calculation of blowout rate is commonly one of the first steps in an Environmental Risk Analysis, ... -
Boundary Condition Treatment in a Transient Flow Model
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-14)Transient flow modelling used for hydraulic calculations and well control evaluations is a vital part to the safety in the industry to properly prepare and build correct procedures when constructing wells. Modeling liquid ... -
