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 ... -
Estimation of Adsorption Capacity of CO2, CH4, and their Binary Mixtures in Quidam Shale using LSSVM: Application in CO2 Enhanced Shale Gas Recovery and CO2 Storage
(Journal article; Peer reviewed, 2020-02)Carbon dioxide enhanced shale gas recovery depends strongly on adsorption properties of carbon dioxide and methane. In this work, Least Squares Support Vector Machine (LSSVM) optimized by Particle Swarm Optimization, has ... -
etrological, geochemical (major, trace, and rare earth elements), and U–Pb zircon data of the Tamatán Group, NE Mexico
(Peer reviewed; Journal article, 2021)From samples of the Paleozoic Tamatán Group (Huizachal–Peregrina Anticlinorium, Tamaulipas, Mexico), petrographic (qualitative and modal) and geochemical analyses (major, trace, and rare earth elements) were conducted. The ... -
Evaluation of Surface-Active Ionic Liquids in Smart Water for Enhanced Oil Recovery in Carbonate Rocks
(Peer reviewed; Journal article, 2023)Ionic modification of injected brines (Smart Water EOR) has previously demonstrated great potential for wettability alteration in carbonates from initially mixed-wet toward more water-wet conditions. However, the efficiency ... -
Experimental Investigation of Material Functions of EOR Polymer Solutions
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)The material functions of multiple EOR polymers were measured and analyzed. Investigating the start-up and relaxation behaviour of multiple polymeric solutions were the main focus of this thesis work. The experimented data ... -
Experimental Reproduction of Wettability for Core Analysis
(PhD thesis UiS;, Doctoral thesis, 2022-09)The ideal scenario when core samples are retrieved from the field to the lab is to start the experiment immediately without any treatment. Due to a decrease in pressure and temperature from reservoir to standard conditions, ... -
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 ... -
Fault Activity Control on Upper Jurassic-Early Cretaceous Wedges in the Snorre Fault Block and its Surrounding Area
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-07)In this study, the question” how fault activity controlled the infill and geometry of the Upper Jurassic-Lower Cretaceous wedges in the Snorre Fault Block and surrounding area” is addressed. To achieve the goal, three-dimensional ... -
Fault Displacement Analysis in the Kalavryta Region of the Corinth Rift System, Greece.
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06-15)The Corinth Rift of Central Greece is one of the world’s most active rifts. Regional N-S extension has resulted in a series of half-grabens within a system of uplifted, rotated and north-dipping normal faults. Extensive ... -
First age constraints of the Marmora Terrane: the missing link for Neoproterozoic geology between South America and southern Africa
(Master thesis, 2021)The Gariep Belt stretches from the southwest of Namibia into the northwest of South America, crossing the international boarder at the Orange River. The mountain belt originates from a continent-continent collision related ... -
Flow behavior of thermo-thickening associative polymers in porous media: effects of associative content, salinity, time, velocity, and temperature
(Peer reviewed; Journal article, 2022)Above a critical temperature, thermo-thickening associative polymers (TAPs) have a superior ability to decrease the mobility of the water phase, compared to traditional polymers for enhanced oil recovery. The ability to ... -
Forecast of investment in renewable energy with consideration of dependency of investment in renewable energy and oil and gas prices
(Master thesis, 2021)Renewables are taking up the role of increasing importance in the energy industry, especially with the recent wave of the drop in prices of oil and gas. Therefore, oil and gas companies are gradually positioning themselves ... -
Fracture analysis and modelling of the South Arne field
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06-14)Fractures are paramount elements in reservoirs, and they are omnipresent in almost all outcrops. The importance of fractures lies in their ability to provide permeable pathways and consequently increase the reservoir ... -
Frequency-dependent AVO inversion applied to physically based models for seismic attenuation
(Peer reviewed; Journal article, 2022)Seismic inversion of amplitude versus offset (AVO) data in viscoelastic media can potentially provide high-resolution subsurface models of seismic velocities and attenuation from offset/angle seismic gathers. P- and S-wave ... -
