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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Development of new oil/water partitioning tracers for the determination of residual oil saturation in the inter-well region of water-flooded reservoirs
(PhD thesis UiS;, Doctoral thesis, 2021-03)Most of the hydrocarbon-rich large unexplored basins are located in remote and/or highly environmentally sensitive regions. As more and more oilfields reach maturity at the end of the secondary stage of recovery, while on ... -
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 ... -
Efficient Optimization and Robust Value Quantification of Enhanced Oil Recovery Strategies
(PhD thesis UiS;, Doctoral thesis, 2022-06)With an increasing demand for hydrocarbon reservoir produces such as oil, etc., and difficulties in finding green oil fields, the use of Enhanced Oil Recovery (EOR) methods such as polymer, Smart water, and solvent flooding ...
