(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-14)Karst cavities and depressions are collectors of various minerals, such as oil and gas, drinking and industrial waters, bauxite, various ores, phosphates, diamonds, gold and tin stone, refractory clay and many others. Of ... -
Drilling Optimisation on the Norwegian Continental Shelf: Opportunities in Well Design Practice
(Master thesis, 2018-04-17)The purpose of this thesis was to attempt to provide evidence that Norway’s drilling fraternity is long overdue for a re-think in the way it drills wells. In so doing, the author has chosen to focus on slim well drilling ... -
Dry reforming of methane over Ni-Fe bimetallic catalyst
(Master thesis, 2021)Our climate is changing for the worse as the concentration of greenhouse gases in the atmosphere increases. Climate change is one of the most important challenges of our time. Emissions of greenhouse gases (GHG) have been ... -
Dynamic Acceptance Criteria for Periodic Testing of Downhole Safety Valves
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-15)Downhole Safety Valves (DHSVs) are periodically leak tested as part of the preventative maintenance program on an oil and gas producing facility. The last couple of years, the oil and gas industry on the Norwegian Continental ... -
Dynamic interfacial tension measurement method using axisymmetric drop shape analysis
(Journal article; Peer reviewed, 2018-06)The current method describes a simple modification to the dynamic and equilibrium interfacial tension (IFT) measurement in a multiphase system (gas-liquid/liquid-liquid) by the Axisymmetric Drop Shape Analysis (ADSA) pendant ... -
Dynamic modelling of ram BOP
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018)As the closing time of Blowout Preventer rams is safety critical, this thesis proposes a dynamic model to calculate the closing time of a ram Blowout Preventer. The thesis work includes guidelines to recreate such a model ... -
Dynamic Performance and Control Strategies of Micro Gas Turbines: State-of-the-Art Review, Methods, and Technologies
(Peer reviewed; Journal article, 2023)The stringent energy and climate change regulations have resulted in a growing share of non-dispatchable renewable energy sources (i.e., solar and wind) in the global energy mix. This has influenced the use of fast and ... -
Early- and Late-Time Prediction of Counter-Current Spontaneous Imbibition, Scaling Analysis and Estimation of the Capillary Diffusion Coefficient
(Peer reviewed; Journal article, 2023-03)Solutions are investigated for 1D linear counter-current spontaneous imbibition (COUSI). It is shown theoretically that all COUSI scaled solutions depend only on a normalized coefficient Λn (Sn) with mean 1 and no other ... -
ECD management and monitoring using High-Speed Wired Drill Pipe Telemetry in a Norwegian Offshore Well
(Master thesis, 2023)Mud weight, or as referred to in this paper as Equivalent Circulating Density, is a crucial element in sustaining wellbore stability and preventing drilling-related issues and has historically been difficult to monitor, ... -
Effect of 15nm SiO2 Nanoparticles on Enhanced Oil Recovery and Drilling Fluid: Experimental and Simulation studies
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Nanotechnology is among the most remarkable technology in the modern science, and due to unique and unrevealed abilities the tiny size of particles possesses, this technology has also been questioned in order to be worthy. ... -
Effect of Al2O3 nanoparticle, Silica Powder microparticle, and Fibers on the newly formulated geopolymer: Experimental and Modelling Studies.
(Master thesis, 2023)When the productivity of a reservoir becomes uneconomical, the final fate of the well is to be plugged and abandoned. NORSOK D-10 defines the well integrity criteria and sets criteria for cement properties to reduce the ... -
Effect of Boron nitride (BN) and surface modified BN on the properties of laboratory water-based drilling fluid formulated in Duovis/XG polymers: Experimental and Simulation studies.
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Properly designed drilling fluid is one of the key factors for efficient and safe drilling operations. Oil-based muds (OBMs) are more extensively used to drill in deeper and harsher environments, where the fluid stability ... -
Effect of buoyancy and inertia on viscoplastic fluid-fluid displacements in a regular and an irregular eccentric annulus
(Peer reviewed; Journal article, 2020-09)Casing strings and liners are important subsurface structural components in petroleum and in geothermal wells. After the casing string has been run in hole, it is cemented to the formation by pumping a sequence of spacer ... -
Effect of Calcium Expansive Additives on the Performance of Granite-Based Geopolymers for Zonal Isolation in Oil and Gas Wells
