Geochemical Characterisation of Oils and Sediments from Cuba and Jamaica; Implications for the Northern Petroleum System
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-07-06)The Caribbean plate has a complex tectonic history and its petroleum potential is relatively unexplored. Jamaica and a large part of Cuba were once part of the Great Arc of the Caribbean (GAC), which was later deformed ... -
Geologisk kartlegging av Stavanger Domkirke og mulige opphavskilder ved lokale øyer (i samarbeid med Arkeologisk Museum)
(Bachelor thesis, 2022)Stavanger Domkirke er en av de eldste domkirkene i Norge. Tross sin status og alder, mangler det dokumentasjon på byggefaser og ressurser brukt i anledning til byggingen av kirken. I dette arbeidet har derfor deler av ... -
Geometrical and kinematical analysis of an extensional fault-propagation fold in the Wisting Field, Norwegian Barents Sea
(Master thesis, 2021)The Wisting field is located on the Bjarmeland Platform northeast of the Maud Basin and adjacent to the Hoop Fault Complex. It is Norway’s northernmost oilfield to be developed. 3D high resolution P-Cable seismic data from ... -
Geomorfologisk effekt på den sedimentære sammensetningen i den permiske Rotliegend-guppen i Nordsjøen
(Bachelor thesis, 2022)Den permiske Rotliegend-gruppen i Nordsjøen er delt inn i to bassenger, det nordlige permiske bassenget og det sørlige permiske bassenget. Det nordlige permiske bassenget, som også omfatter den norske sektoren, er mindre ... -
Geothermal gradient from well log data in the Froan and Gimsan basins, Norwegian Sea
(Bachelor thesis, 2023)This thesis reconstructs geothermal gradients in the Froan and Gimsan basins of the Norwegian Sea, utilizing well log data to derive a more accurate representation of the thermal regime of these basins. The study challenges ... -
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 ... -
Halokinesis influence on the Triassic deposition and the evolution of minibasins in the Central North Sea
(Master thesis, 2021)The main focus of this study is to improve the understanding about the lateral variation of the Zechstein Group and the impact on the Triassic sedimentary minibasins. The study area is located approximately 225 km south-west ... -
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 ... -
High-Resolution Topographic and Chemical Surface Imaging of Chalk for Oil Recovery Improvement Applications
(Peer reviewed; Journal article, 2022-03)Chalk is a very fine-grained carbonate and can accommodate high porosity which is a key characteristic for high-quality hydrocarbon reservoirs. A standard procedure within Improved Oil Recovery (IOR) is seawater-injection ... -
Holistic 3D Model of an Urban Area in Norway: An Integration of Geophysical, Geotechnical, Remote Sensing, and Geological Methods
(Peer reviewed; Journal article, 2023)Understanding the distribution and characterization of natural and non-natural materials on the surface and near-subsurface is important for the development of infrastructure projects. This may be a challenge in highly ... -

How diagenetic rock composition and mineralogical changes associated with water injection affect geomechanics and fluid behaviour in chalk i.e. producibility (IOR)
(PhD thesis UiS; 774, Doctoral thesis, 2024)Geo-mechanical responses associated with seawater injection for improved oil recovery (IOR) processes have been thoroughly investigated during the last few decades. It has been suggested that the presence of non-carbonate ... -
Hvordan bestemme settedyp for fôringsrør.
(Bachelor thesis, 2022)Det viktigste for valg av settedyp og formasjonsvalg for de ulike foringsrørene er å avgjøre hvor de trengs. Man må regne med å måtte øke slamvekten som følge av økende poretrykk. Fra poretrykksberegninger og formenasjons-styrke ... -
Hybridization of gradient-based and gradient-free optimization techniques for simultaneous optimization of number of wells, their location and drilling time in a 2-dimensional reservoir
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Optimization has always been a challenging scope in any field of science, and reservoir management is no exception. By the advent of computational power, the use of mathematical algorithms in conjunction with reservoir ... -
Hydrogen diffusion into caprock: A semi-analytical solution and a hydrogen loss criterion
(Peer reviewed; Journal article, 2023)Depleted gas reservoirs can provide a gigaton capacity and the necessary infrastructure for large scale hydrogen storage. Therefore, underground storage of hydrogen in these geological formations is considered a valuable ... -
