An Experimental Study of the Enhanced Mass Transfer Process by CO2 Absorption for Carbon Storage in Saline Aquifers
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-21)Diffusion of CO2 into water-based solutions generate an instability at the interface as a result of density differences. The rate of dissolution, the final saturation pressure and the mixing regime caused by convection ... -
Experimental Study on Automatic Evaluation of Drilling Fluid Properties
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)The drilling fluid has several important functions such as transporting cuttings out of the well and being a primary barrier during the drilling operation. When drilling challenging wells in the present and future, factors ... -
Experimental study on cuttings transportation in turbulent pipe flow
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Experimental investigation on cuttings transportation in turbulent flow, in both horizontal and inclined pipes were performed in the multiphase-laboratory at the University of Stavanger. Spherical glass particles were used ... -
Experimental study on parametric configurations of artificially downwelling aerations in stratified water
(Peer reviewed; Journal article, 2023)Downwelling aeration has become a widely applied approach to cope with the water eutrophication in stratified reservoirs, rivers and lakes. The aeration parameters involving flow rate, flow locations and working periodicity ... -
Experimental study on thermal effects on well components
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)The main objective of inflow control devices is to maintain a uniform inflow by providing an additional pressure loss between the formation and the wellbore. ICDs delay the production of water or gas, and thus increase the ... -

Explainable artificial intelligence for human-machine interaction in brain tumor localization
(Peer reviewed; Journal article, 2021)Primary malignancies in adult brains are globally fatal. Computer vision, especially recent developments in artificial intelligence (AI), have created opportunities to automatically characterize and diagnose tumor lesions ... -
Explicit and implicit inclusion of time in the definitions of risk and reliability
(Peer reviewed; Journal article, 2020)In safety, understanding of risk and reliability is generally not possible without reference to time. For example, regarding the risk of some activity or situation, focus is on what might happen in future time in relation ... -
Exploiting epistemic uncertainty of the deep learning models to generate adversarial samples
(Peer reviewed; Journal article, 2022)Deep neural network (DNN) architectures are considered to be robust to random perturbations. Nevertheless, it was shown that they could be severely vulnerable to slight but carefully crafted perturbations of the input, ... -
Exploiting the geochemical attributes of migrated oils for an improved understanding of their sourcing facies : Lessons learned from the southeastern Caribbean and the Norwegian Barents and North Seas
(PhD thesis UiS;, Doctoral thesis, 2023-01)Assessing the geochemistry of oils and the source rock facies from which they originated is crucial in petroleum systems analysis. Crude oils are usually available for geochemical characterization, but pertinent source ... -
Exploits, advances, and challenges benefiting beyond Li-ion battery technologies
(Peer reviewed; Journal article, 2019)The battery market is undergoing quick expansion owing to the urgent demand for mobile devices, electric vehicles and energy storage systems, convoying the current energy transition. Beyond Li-ion batteries are of high ... -
Exploration and evaluation of offshore repurposing concepts
(Master thesis, 2022)Økende etterspørsel etter ressurser, en global miljøkrise og politiske uroligheter krever nye måter å drive forretning på, og løsningen kan være å skape et fungerende forhold mellom økonomisk utvikling og økologiske systemer ... -
