The impact of salt tectonics on the Mesozoic sedimentation and petroleum systems of the Norwegian Barents Sea
(PhD thesis UiS;540, Doctoral thesis, 2020-09)In the Norwegian Barents Sea, Mesozoic and Cenozoic mobilization of Pennsylvanian-lower Permian layered evaporite sequences (LES) resulted in areas with salt tectonics (e.g. Nordkapp, Tromsø and Tiddlybanken basins), which ... -
Interaction between two calcite surfaces in aqueous solutions: Study of nano-scale interfacial forces using AFM and SFA
(Doctoral thesis, 2019-11)Carbonate-bearing rocks in the upper Earth’s crust are prone to continuous changes under influences of various physical and chemical processes. The macroscopic mechanical strength of carbonates is generally controlled by ... -
Low Carbon Enhanced Oil Recovery Solution for Carbonates
(PhD thesis UiS;, Doctoral thesis, 2024)Oil production from mature fields causes significant CO2 emissions, primarily linked to the management and processing of injected and produced water. As fields age, the demand for injected water increases, increasing both ... -
Novel Principles for Effective Earth Model Grid Management while Geosteering
(PhD thesis UiS;409, Doctoral thesis, 2018-09)The aim of geosteering is to place the well optimally in the reservoir, based on the available measurements and interpretations of the geology. The interpretations are captured in earth models that are used for decision ... -
Permeability evolution in chalk linked to stress and thermochemical aspects of North Sea reservoir conditions
(PhD thesis UiS;564, Doctoral thesis, 2020-12)The project was initiated by The National IOR Centre of Norway within the University of Stavanger and it aligns with the overall goal of the centre to improve oil recovery on the Norwegian Continental Shelf. It contributes ... -
Robust Decision and Data Science Application for Reservoir Management : Probabilistic Forecasting, History Matching, Sequential Decision Making and Value-of-Information
(PhD thesis UiS;, Doctoral thesis, 2023-01)Reservoir Management (RM) is defined as the utilization of available technology, financial assets, and human resources to maximize the economic recovery of a reservoir. This type of management involves a series of operations ... -
The Seismic Imaging and Interpretation of Faults: A Case Study from the Snøhvit Field, Barents Sea
(PhD thesis UiS;568, Doctoral thesis, 2021-01)An accurate understanding of faults in the subsurface is critical to successful petroleum exploration and production. Faults define sediment distribution pathways during deposition, act as barriers or conduits to fluid ... -
Sequential drilling decisions based on explicit joint probability distribution of spatially distributed subsurface data: Modeling and value creation propositions
(PhD thesis UiS;, Doctoral thesis, 2024)Revenue from hydrocarbon production depends on physical properties whose values change spatially and only sampled in a few locations by the time of capital commitment. Drilling new wells enables hydrocarbon production, but ... -
Synthetic polymers for Enhanced Oil Recovery; Mechanical degradation, and alleviation thereof : Experimental study across scales in pipes, chokes, and porous media of regular HPAM, HPAM-ATBS co-polymers, and TAPs
(PhD thesis UiS;, Doctoral thesis, 2021-06)This thesis and the related work concern synthetic polymers for enhanced oil recovery, their ability to reduce the mobility of the water phase during oil recovery, and their predisposition to mechanically break when subjected ... -
Thermal properties of reservoir rocks, role of pore fluids, minerals and digenesis. A comparative study of two differently indurated chalks
(PhD theses;494, Doctoral thesis, 2020-01)Carbonate rocks are distressed by temperature fluctuations, most commonly observed in marble monuments and cladding exposed to varying outdoor temperatures. Similarly, reservoir rocks are cooled on periodic basises during ...
