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 ... -

Hyper-parameter optimization for improving the performance of localization in an iterative ensemble smoother
(Peer reviewed; Journal article, 2023)This work aims to help improve the performance of an iterative ensemble smoother (IES) in reservoir data assimilation problems, by introducing a data-driven procedure to optimize the choice of certain algorithmic ... -
IMPACT OF DATA PRE-PROCESSING TECHNIQUES ON MACHINE LEARNING MODELS
(Master thesis, 2022)The Volve dataset, which contains the time series values of different sensors that have been used at the Volve drilling site contains many flaws which make it hard for machine learning models to learn from the dataset and ... -
Impact of risk attitude on optimal IOR initiation time: A case study solved in a sequential decision-making framework powered by machine learning-based non-linear regression
(Master thesis, 2023)The least-squares Monte Carlo algorithm (LSM) is an efficient approximate dynamic programming algorithm for solving sequential decision-making problems, leveraging regression. Previous studies have showcased the LSM workflow ... -
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 ... -
The Impact of Salt Tectonics on the Thermal Evolution and the Petroleum System of Confined Rift Basins: Insights from Basin Modeling of the Nordkapp Basin, Norwegian Barents Sea
(Peer reviewed; Journal article, 2019-07)Although the thermal effect of large salt tongues and allochthonous salt sheets in passive margins is described in the literature, little is known about the thermal effect of salt structures in confined rift basins where ... -
The impact of seismic interpretation methods on the analysis of faults: a case study from the Snøhvit field, Barents Sea
(Peer reviewed; Journal article, 2021)Five seismic interpretation experiments were conducted on an area of interest containing a fault relay in the Snøhvit field, Barents Sea, Norway, to understand how the interpretation method impacts the analysis of fault ... -
Implementation of Adaptive Localization for Enhancing Ensemble-Based History Matching in Hydrocarbon Reservoir Management
(Master thesis, 2022)In reservoir management, the ensemble-based history matching is applied to quantify and update uncertainty in reservoir characterization with the main objective to support high quality decisions. However, the ensemble-based ... -
