Comparing hydro- and wind electricity sources in Norway.
(Bachelor thesis, 2023)The motivation for this study was to get a better understanding of the two main power production methods, as more and more wind power plants are appearing in Norway, alongside a rise in the export of electricity overseas. This ... -
Comparing photogrammetric and iPad-Lidar models of exposed faces in the Rogfast tunnel.
(Bachelor thesis, 2022)Cameras have become progressively more advanced in the 21st century. They are a ubiquitous feature in electronic devices, which brings more opportunities for collecting data in the field and creating 3D geologic models. ... -
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, ... -
Comparison of intercept methods for correction of steady state relative permeability experiments for capillary end effects
(Peer reviewed; Journal article, 2022)Steady-state relative permeability experiments are performed by coinjection of two fluids through core plug samples. The relative permeabilities can be calculated using Darcy’s law from the stabilized pressure drop and ... -
Compositional variation of the Zechstein Group in the Norwegian North sea: Implications for underground storage in salt caverns
(Peer reviewed; Journal article, 2023)Halite beds in the upper Permian Zechstein Group represent an opportunity for the future development of underground storage caverns. However, geological factors such as lithological heterogeneities, cap rock characteristics ... -
Conditional data generation for an improved diagnosis in prostate cancer
(Master thesis, 2021)Prostate Cancer is the second most common cancer in men worldwide, the fourth most commonly occurring cancer overall and the sixth leading cause of cancer death among men worldwide. Early detection of prostate cancer is ... -
Constrained non-linear AVO inversion based on the adjoint-state optimization
(Peer reviewed; Journal article, 2022)Pre-stack AVO inversion of seismic data is a modeling tool for estimating subsurface elastic properties. Our focus is on the model-based inversion method where then unknown variables are estimated by minimizing the misfit ... -
Contribution of Geosciences in the Study of Anthropogenic Activities in Different Temporal and Spatial Contexts
(PhD thesis UiS;, Doctoral thesis, 2024)From Homo sapiens, anthropogenic activities have impacted Earth systems at different spatial and time scales, particularly since the mid-twentieth century as the geological record confirms. Such impact has triggered Earth ... -
Controls and Distributions Of Tertiary Sandstones in Southern Viking Graben
(Master thesis, 2022)The Tertiary succession in the Ve Sub-basin, Sleipner Terrace, Utsira High and Ling Depression is studied to understand the lateral and vertical distribution of Tertiary sandstones, to know if Tertiary tectonics had an ... -
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 ... -
Core wettability reproduction: A new solvent cleaning and core restoration strategy for chalk cores
(Peer reviewed; Journal article, 2020)Laboratory core restoration procedures include different core cleaning solvents, establishment of initial water saturation (Swi) by diverse techniques and processes of crude oil exposure that influence the final core wetting ... -
Core-scale sensitivity study of CO2 foam injection strategies for mobility control, enhanced oil recovery, and CO2 storage
(Peer reviewed; Journal article, 2020)This paper presents experimental and numerical sensitivity studies to assist injection strategy design for an ongoing CO2 foam field pilot. The aim is to increase the success of in-situ CO2 foam generation and propagation ... -
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 ... -
Data assimilation with soft constraints (DASC) through a generalized iterative ensemble smoother
(Peer reviewed; Journal article, 2022)This work investigates an ensemble-based workflow to simultaneously handle generic, nonlinear equality and inequality constraints in reservoir data assimilation problems. The proposed workflow is built upon a recently ... -
Debiasing probabilistic oil production forecasts
(Peer reviewed; Journal article, 2022)Exploration and production companies in the hydrocarbon industry have every interest in producing unbiased production forecasts at the time of the investment decision, since it is an intrinsic part of making oil field ... -
Decision-Driven Data Analytics for Well Placement Optimization in Field Development Scenario - Powered by Machine Learning
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Application of Data Analytics and Machine Learning (ML) in petroleum reservoir management have received a lot of attention in recent years, mainly due to the availability of sheer computational resources and recorded big ... -
