Effect of Input Parameters on Basin Modelling and Hydrocarbon Resource Assessment of the Northern North Sea
(Master thesis, 2011)3D basin modelling and petroleum system analysis of the northern North Sea has been carried out using the Petromod software. The model was calibrated using well 34/8-7 in the Visund field. Different input parameters such ... -
The effect of mechanical activation in the production of olivine surface area
(Peer reviewed; Journal article, 2016)This study investigates the effect of dry mechanical activation of olivine as a pre-treatment step prior to wet milling with respect to the production of specific surface area. Milling experiments combining the two milling ... -
Effect of non-linear elasticity on stress paths in depleted reservoirs and their surroundings
(Chapter, 2020)The prediction of stress and strain changes in and around reservoir using numerical simulators is often based on assumption of linear elasticity before reaching yield point. However, it is known that rocks are generally ... -
The Effect of Partial CO2 Saturation on the Elastic Properties of Castlegate Sandstone Measured at Seismic and Ultrasonic Frequencies
(Master thesis, 2016)The Oil & Gas industry started to tackle the problem of CO2 emissions through subsurface storage in depleted reservoir formations. Such are the cases of the Sleipner West Field in the North Sea (Eiken, Brevik et al. 2000), ... -
Effect of Preconditioning and Ageing on Rheological Properties of Model Drilling Fluids
(Chapter, 2017)Many drilling fluids are thixotropic, meaning that viscosity decreases with time when subjected to shear. Other fluids may show anti-thixotropic (rheopectic) behavior, i.e. viscosity increase with time when subjected to ... -
The effect of preparation time and aeration rate on the properties of bulk micro-nanobubble water using hydrodynamic cavitation
(Peer reviewed; Journal article, 2022)Fundamental research on bulk micro-nanobubbles (BMNBs) has grown rapidly due to the demand for their industrial applications and potential role in interfacial sciences. This work focuses on examining properties of such ... -
Effect of pressure fluctuations in long-term stability of unlined pressure shaft at Svandalsflona Hydropower project, Norway
(Chapter, 2019)The main design principle of unlined pressure tunnels/shafts in a hydropower scheme is to provide sufficient confinement (minor principal stress) to withstand the internal hydrostatic water pressure. Rock support is only ... -
Effect of Relative Permeability on History Matching a Permian Basin Oil Well
(Master thesis, 2015)Production from shale oil and gas has increased significantly the last couple of decades. The industry is constantly developing horizontal well and stimulation technology to increase production from these wells. Data ... -
Effect of roasting pretreatment on micro-nanobubble-assisted flotation of spent lithium-ion batteries
(Peer reviewed; Journal article, 2023)In this research study, a novel process of roasting-assisted flotation was developed for the separation of spent vehicle lithium-ion batteries (LIBs) in the presence of micro-nanobubbles (MNBs). For this purpose, roasting ... -
Effect of Salinity and Nanoparticles on Interfacial Tension and Wettability: Micromodel Experimental Investigation
(Master thesis, 2021)Using low-saline water and nanofluids has been suggested as novel enhanced oil recovery methods in the oil industry over the recent decades. Previous research has shown higher recovery factor is expected during low salinity ... -
Effect of syneresis on oil-based drilling fluid stability
(Master thesis, 2020)Når fenomenet synerese oppstår, induserer det settling og utfelling (sag) av vektpartikler i borevæsken. Denne effekten kan forårsake forskjellige boreproblemer, for eksempel fastkjøring av rør, redusert borehastighet eller ... -
Effect of ultrasound pre-treatment on carbonaceous copper-bearing shale flotation
(Peer reviewed; Journal article, 2022)Although numerous studies have been implemented on identifying the impact of acoustic waves on mineral beneficiation, its fundamental aspects remain unclear in the literature. The present work, for the first time, ... -
The effect of upstream inlet choking and surfactant addition on the performance of a novel parallel pipe oil-water separator
(Peer reviewed; Journal article, 2020)This paper reports the effect of inlet choking and addition of surfactant on the performance of a parallel pipe oil-water separator. These two issues can have a strong effect on oil-water separation in real hydrocarbon ... -
EFFECT OF WATER QUALITY ON SPONTANEOUS IMBIBITION IN CARBONATE CORES
(Master thesis, 2021)Forskningsspørsmålet i dette arbeidet var effekten av vannkvalitet på spontan oppsuging (SI) i karbonatkjerner. Målet var å endre fra oljefuktende til vannfuktende tilstand kjerner for å oppnå mer spontan oppsuging av vann ... -
Effect of Water Quality on Wettability Alteration in Carbonates
(Master thesis, 2019)The topic of the master's thesis is the wettability alteration in carbonates by Low Salinity enhanced oil recovery (EOR). Wettability alteration towards more water-wet upon reduction of salinity and/or manipulation of ionic ... -
The effect of wettability and flow rate on oil displacement using polymer-coated silica nanoparticles: A microfluidic study
(Peer reviewed; Journal article, 2020)Polymer-coated silica nanoparticles (PSiNPs) have been experimentally investigated in core- and micro-scale studies for enhanced oil recovery (EOR). Wettability and flow rate have a considerable effect on oil displacement ... -
EFFECTIVE ANISOTROPY VERSUS FLUID SATURATION
(Master thesis, 2015)Anisotropy has proved to be a reliable means for determination of the rock properties necessary to characterize the subsurface. VTI is a form of anisotropy which provides an estimate of the layered earth. This report ... -
