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 ... -
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 ... -
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 ... -
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 ... -
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 ...
