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. ... -
Application of Elastic Full-Waveform Inversion on Blackfoot Data
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06-20)Estimating a high resolution image of the subsurface has been always a challenge in the oilfield exploration. With advances in computational power, Full Waveform Inversion (FWI) has been proven as an efficient imaging ... -
Architecture of shoreface to deep-water systems in segmented rift systems: Evidence from the southern margin of the Sogn Graben, northern North Sea
(Peer reviewed; Journal article, 2020-03)Naturally fractured reservoirs are highly dependent on capillary forces to recover hydrocarbons during water injection. Water can spontaneously imbibe and expel oil if positive capillary forces exist; purely counter-current ... -
Characterization of Nannofacies in Upper Cretaceous Chalks used in IOR Research
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-07)The aim of this thesis is to contribute to enhanced oil recovery (EOR) research by characterizing nannofacies in chalk samples used in increased oil recovery (IOR) flooding experiments with a MgCl2 brine at reservoir ... -
Comparison of facies models based on stochastic versus deterministic AVO inversion
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020)This thesis compares facies models based on deterministic AVO inversion – which is a standard approach in the industry, and stochastic AVO inversion – which is a newer, less popular approach, but according to literature, ... -
Controls of basin margin tectonics on the Lower Cretaceous sedimentation in the Norwegian Barents Sea
(PhD thesis UiS;530, Doctoral thesis, 2020-06)Structural styles and stratigraphic patterns along North Atlantic margins display a large spectrum of complexity and variability. An extensive amount of subsurface data from the north-central and south-western Barents Sea ... -
Data Assimilation Methods in Seismic Inversion
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06)Full-waverform inversion (FWI) is a powerful tool for getting high resolution images from seismic data to understand formations and the reservoir characteristics. But the inversion problems usually do not have unique ... -
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 ... -
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 ... -
Ground penetrating radar and seismic study to determine glacial deposit stratigraphy
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06-14)This work reviews two near-surface geophysical methods, ground penetrating radar and seismic, covering all the processes from the data acquisition to the interpretation. The area of study, Jæren, is located over glacial ... -
High resolution heavy mineral studies from Silurian to Triassic successions exposed in the Altiplano of Bolivia (Central Andes)
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020)Heavy mineral studies play an important role in the understanding of a clastic sediment or sedimentary rock. The mineral composition of a clastic rock may reflect the provenance and sedimentological processes such as sorting ... -
The Impact of Salt Tectonics on the Thermal Evolution and the Petroleum System of Confined Rift Basins: Insights from Basin Modeling of the Nordkapp Basin, Norwegian Barents Sea
(Peer reviewed; Journal article, 2019-07)Although the thermal effect of large salt tongues and allochthonous salt sheets in passive margins is described in the literature, little is known about the thermal effect of salt structures in confined rift basins where ... -
