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

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 ... -
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 ... -
