Early and Late Time Analytical Solutions for Co-current Spontaneous Imbibition and Generalized Scaling
(Peer reviewed; Journal article, 2020)We propose an explicit analytical solution for 1D cocurrent (COC) spontaneous imbibition (SI) in which a core is exposed to water (inlet) and oil (outlet). The system is described using an advection-capillary diffusion ... -

Effect of Initial Wettability on Rock Mechanics and Oil Recovery: Comparative Study on Outcrop Chalks
(Peer reviewed; Journal article, 2020)Brines containing surface-active divalent ions such as Ca2+, Mg2+ and SO42− impact the stiffness, strength and time-dependent deformation of water wet Mons outcrop chalk. This study documents how stiffness and strength of ... -
Effect of Wettability on Waterflooding and Relative Permeability at Slightly Water-Wet Conditions
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)The wettability of a porous system is of high importance when waterflood behavior and relative permeability are investigated, because both will be strongly affected. Adsorption of polar organic components (POC) are responsible ... -
Effect of Wettability on Waterflooding and Relative Rermeability at Medium Water-Wet Conditions.
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)This project contributes with experimental measurement that could increase our understanding on how relative permeability is affected by wettability during an oil recovery process. Wettability has significant attention ... -
Effective Management of Hybrid Workloads in Public and Private Cloud Platforms
(Master thesis, 2023)As organizations increasingly adopt hybrid cloud architectures to meet their diverse computing needs, managing workloads across on-premises and on multiple cloud environments has become a critical challenge. This thesis ... -
Effective fluid bulk modulus in the partially saturated rock and the amplitude dispersion effects
(Peer reviewed; Journal article, 2020)Frequency dispersion is a well-known effect in geophysics, which means that waves of different wavelengths propagate at different velocities. Amplitude dispersion is a less-known effect, which means that waves of different ... -
Effectiveness of Frantz Machine for Separation of Heavy Minerals
(Master thesis, 2021)This project research the provenance of Precambrian formations: Vredefontein Formation, Grootderm Formation, and Derburg Formation from Namibia. The aim is to enhance provenance understanding after the separation of minerals ... -
Effects of permeability on CO2 dissolution and convection at reservoir temperature and pressure conditions: A visualization study
(Peer reviewed; Journal article, 2020-06)When CO2 is injected into aquifers, CO2 will dissolve into the water phase. CO2 dissolution initiated by diffusion, will increase the density of the water phase and thereby commence the convective flow of CO2. The objective ... -
Effects of pore fluids on quasi‐static shear modulus caused by pore‐scale interfacial phenomena
(Peer reviewed; Journal article, 2019)It is evident from the laboratory experiments that shear moduli of different porous isotropic rocks may show softening behaviour upon saturation. The shear softening means that the shear modulus of dry samples is higher ... -
Efficient Dimensionality Reduction Methods in Reservoir History Matching
(Peer reviewed; Journal article, 2021-05)Production forecasting is the basis for decision making in the oil and gas industry, and can be quite challenging, especially in terms of complex geological modeling of the subsurface. To help solve this problem, assisted ... -
Efficient Optimization and Robust Value Quantification of Enhanced Oil Recovery Strategies
(PhD thesis UiS;, Doctoral thesis, 2022-06)With an increasing demand for hydrocarbon reservoir produces such as oil, etc., and difficulties in finding green oil fields, the use of Enhanced Oil Recovery (EOR) methods such as polymer, Smart water, and solvent flooding ... -
En gjennomgang av energi produserer og lagring i geotermisk energi, og geotermiske brønner og boring
(Bachelor thesis, 2021)Geotermisk energi er en av de raskest voksende fornybare energikildene i dag. Det er en grunnleggende fornybar ressurs siden varme genereres kontinuerlig over hele jorden og fortsatt er tilgjengelig gjennom hele året. Det ... -
Energi til norsk veksthusnæring - bruk av naturgass som energibærer og CO2-kilde
(Bioforsk Rapport;, Research report, 2006)Norsk gartnerinæring bruker anslagsvis 1 000 GWh per år. Planteproduksjon i veksthus her i landet har stort behov for elektrisk energi og avhengig av kultur og produksjonsopplegg varierer andelen elektrisk energi fra 50-80 ... -
Enhancing regional scientific knowledge for the Ritland Impact Crater: Meteorite classification, mineralogical and impact shock characteristics
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-08-14)Impactites from the Cambrian aged 2,7 km diameter Ritland impact crater in southwestern Norway were studied in detail using methods such as SEM (Scanning Electron Microscope), ICP-MS geochemistry, PGE (Platinum Group ... -
Ensemble-based constrained optimization using an exterior penalty method
(Peer reviewed; Journal article, 2021)In science and engineering, non-linear constrained optimization has been a useful mathematical technique for many practical applications. Of interest to us is its applicability in the modeling and prediction of hydrocarbon ... -
EOR by Seawater and “Smart Water” Flooding in High Temperature Sandstone Reservoirs
(PhD theses (TN-lER);508, Doctoral thesis, 2020-04)In the last decades, when the first treated injection water has resulted in incremental oil recovery, the activity to explore this technique has increased. And today, Smart Water flooding or low salinity flooding in sandstone ... -
