A numerical study of density-unstable reverse circulation displacement for primary cementing
(Peer reviewed; Journal article, 2022)Primary cementing of the casing string is the operation where the annular space behind the casing is displaced to a cement slurry. Once hardened, the cement should form a solid annular barrier and provide zonal isolation ... -
A Numerical Study of Pressure Build Up due to Kick Migration in a Closed Well Filled with Water-Based Mud
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-15)There has been considerable and diverging discussion in the academic literature regarding the real gas kick velocity. This thesis contributes to improving and sharing the knowledge about the real gas kick velocity. It is ... -
Ocean & climate lab scale model - Thermal circulation with surface wind drive
(Master thesis, 2021)Background: The earth receives more heat from the sun at the equator than at the poles. This imbalance is offset by the fact that heat is continuously transported from low-latitude oceans by large-scale winds and ocean ... -
Offshore Electrification - An overview of technologies, risks and costs associated to the Norwegian Continental Shelf
(Master thesis, 2022)The concentration of greenhouse gases in the atmosphere is increasing rapidly because of burning fossil fuels. To reduce future emissions, the electrification of offshore oil and gas installations is discussed. The ... -
Offshore wind: Investment decision model
(Master thesis, 2021)Climate change-related concerns force nations to reduce greenhouse gas emissions using renewable energy sources. Wind power is one of the fastest-growing power generation sources worldwide. Over the past decade, offshore ... -
Oil-based drilling fluid's cuttings bed removal properties for deviated wellbores
(Peer reviewed; Journal article, 2021)Results from cuttings transport tests in the laboratory using different field-applied oil-based drilling fluids with similar weight and varying viscosities are presented in this paper. The fluids are designed for highly ... -
On the numerical discretization of a tumor progression model driven by competing migration mechanisms
(Peer reviewed; Journal article, 2021)In this work we explore a recently proposed biphasic cell-fluid chemotaxis-Stokes model which is able to represent two competing cancer cell migration mechanisms reported from experimental studies. Both mechanisms depend ... -
On the Viability of Lithium Bis(fluorosulfonyl)imide as Electrolyte Salt for Use in Lithium-Ion Capacitors
(Peer reviewed; Journal article, 2023)Lithium-ion capacitors (LICs) represent promising high-power energy storage devices, most commonly composed of a lithium-ion intercalation anode (e. g., graphite or hard carbon), a supercapacitor activated carbon (AC) ... -
Openhole Sidetrack Operations: Drill Bit Design and BHA Configuration Influence in Drilling Performance
(Master thesis, 2021)Sidetrack is a typical drilling technique in which a deviation is made from an already existing well from a position other than its end. Several openhole sidetracks have been performed over the last couple of years in ... -
Optimal Core Restoration and the Effect of Initial Wetting on Oil Recovery in Chalk
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-12-15)The initial wetting condition of the reservoir rock is fundamental in the advanced oil recovery methods by waterflooding, in particular, in Smart Water EOR. The wettability alteration of the rock surface is induced by ... -
