Acquisition, Processing and Interpretation of Ground Penetrating Radar (GPR) Data in Aidonia, Greece
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020)The Mycenaean Cemetery of Aidonia, Greece, is located about 10 km west of the town of New Nemea on the Peloponnese peninsula. In this cemetery, a number of chamber tombs dating from 1600-1100 B.C. was discovered in the ... -
Adaptive machine learning-based surrogate modeling to accelerate PDE-constrained optimization in enhanced oil recovery
(Peer reviewed; Journal article, 2022)In this contribution, we develop an efficient surrogate modeling framework for simulation-based optimization of enhanced oil recovery, where we particularly focus on polymer flooding. The computational approach is based ... -
Adhesive forces between two cleaved calcite surfaces in NaCl solutions: The importance of ionic strength and normal loading
(Journal article; Peer reviewed, 2018-12-15)The mechanical strength of calcite bearing rocks is influenced by pore fluid chemistry due to the variation in nano-scale surface forces acting at the grain contacts or close to the fracture tips. The adhesion of two ... -
Adjoint-state method for seismic AVO inversion and time-lapse monitoring
(PhD thesis UiS;, Doctoral thesis, 2023)This dissertation presents seismic amplitude versus offset (AVO) inversion methods to estimate water saturation and effective pressure quantitatively in elastic and viscoelastic media. Quantitative knowledge of the saturation ... -
Age and Provenance study of Paleoarchean rocks from the Singhbhum Craton (India)
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-08-13)This study has performed in situ U-Pb and Lu-Hf isotope analysis on zircons and in situ U-Pb isotope analysis on apatites, by LA-ICP-MS and MC-ICPMS, from three Tonalite-Trondhjemite-Granodiorite (TTG) samples from ... -
An Integrated Study of the Oligocene Sequence Stratigraphic Framework in the Egersund Basin, Norwegian North Sea
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-07-13)The Oligocene interval of the Egersund basin in the Norwegian North Sea is under-studied stratigraphic successions due to its minor significance for the oil and gas industry. The purpose of this study was to improve the ... -
An Integrated Study of the Transition of the Ula Formation from the Cod Terrace to the Sørvestlandet High; Implications for Reservoir Types, Distribution, and Carrier Beds for Hydrocarbon Migration
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-07)The Upper Jurassic deposits of the Eastern Margin in the Central Graben were influenced by syn-depositional halokinesis, which in turn affected the partitioning of environments and the resulting stratigraphic architecture. ... -
Analysis of filtering techniques for investigating landslide-induced topographic changes in the Oetz Valley (Tyrol, Austria)
(Peer reviewed; Journal article, 2020)Landslides endanger settlements and infrastructure in mountain areas across the world. Monitoring of landslides is therefore essential in order to understand and possibly predict their behavior and potential danger. ... -
Analysis of wind and response measurement data from a suspension bridge
