Exploring the behaviour of Silicon by empirical analysis of galvanostatic charge-discharge curves
(PhD Theses;, Doctoral thesis, 2024)The capability of battery materials to deliver not only high lithium (Li) storage capacity, but also the ability to operate at high charge/discharge rates is an essential property for development of new batteries. First, ... -
FAITH AND MOBILITY OF HYDROGEN IN GEOLOGICAL POROUS MEDIA
(Master thesis, 2022)Large-scale hydrogen storage can help alleviate the main drawbacks of renewable energy generation, their intermittency, and their seasonal and geographical constraints. Renewable energy without energy storage is unable to ... -
The fate of hydrocarbon leaks from plugged and abandoned wells by means of natural seepages
(Peer reviewed; Journal article, 2020-10)When a well reaches the end of its productive life, it is permanently plugged and abandoned. Even though new technology and verification methods are being evaluated, it is evident that operational, barrier material and ... -
FEM Modelling and Simulation of Production Casing with Local Wear Damage
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Field data show that casing and production tubing experiences wear on both the internal and external parts of the tubular. The main mechanisms of the wear are the mechanical friction between drill string and casing, ... -

(Master thesis, 2021)This thesis will present relevant literature study, data quality assertion and performance evaluation and economic considerations based on field data from Valhall Flank West. The aim is to investigate, explain and suggest ... -
FIELD-SCALE GENERALITY OF THE MACHINE LEARNING MODELS
(Master thesis, 2022)Drilling performance is directly related to fundamental aspects such as drilling variables that can affect the performance of the operation, the well stability, efficiency of drilling equipment, use of new technologies and ... -
Fixed type-oscillating water column front wall angle variation and impact on chamber performance: CFD numerical wave tank assessment
(Peer reviewed; Journal article, 2023)This study investigates optimizing the front wall geometry of an Oscillating Water Column (OWC) chamber to enhance turbine performance and output efficiency when harnessing energy from progressive waves with consistent ... -
Flexible Geopolymer for Oil and Gas Well Cementing: An Experimental Study
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)Conventional wellbore cementing materials used in the oil and gas industry are normally brittle, have low tensile strength and suffer from shrinkage. These properties affect the performance of these materials in downhole ... -
Flow Investigation of Stall and Choke on Axial Compressor using CFD
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)The complicated nature of axial compressor fluid dynamics instabilities such as stall and choke when utilizing air power left a lot of room for investigation during the state of operation. This dynamic instabilities ... -

Fluid flow properties of the Wilhelmøya Subgroup, a potential unconventional CO2 storage unit in central Spitsbergen
(Journal article; Peer reviewed, 2018-11)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
Fluid Migration Characterization of Full-scale Annulus Cement Sections Using Pressure-Pulse-Decay Measurements
(Peer reviewed; Journal article, 2021)Fluid migration behind casings is a well integrity problem that can result in sustained casing pressure, undetected leaks to the environment, and potentially very challenging remediation attempts. Understanding the geometric ... -
Fluid-Rock Interactions for CO2 Geological Storage in Chalk
(Master thesis, 2022)CCS has been recognized as an effective strategy to limit the temperature rise to 1.5 °C by 2050 under the Paris Agreement. As a result, more than 50 CCS pilot or large-scale projects have been commissioned in recent ... -
Fluid-sensitive migration mechanisms predict association between metastasis and high interstitial fluid pressure in pancreatic cancer
(Peer reviewed; Journal article, 2022)A remarkable feature in pancreatic cancer is the propensity to metastasize early, even for small, early stage cancers. We use a computer-based pancreatic model to simulate tumor progression behavior where fluid-sensitive ... -
Footprints of spontaneous fluid redistribution on capillary pressure in porous rock
(Journal article; Peer reviewed, 2017-05)Pore-scale imaging of two-phase flow in porous media shows that pore filling occurs as cooperative events with accompanying spontaneous fluid redistribution in other parts of the pore space. We present a level set method ... -
