Structural evolution of sheared margin basins: the role of strain partitioning. Sørvestsnaget Basin, Norwegian Barents Sea
(Journal article; Peer reviewed, 2017-07)Spatio-temporal analysis of basins formed along sheared margins has received much less attention than those formed along orthogonally extended margins. Knowledge about the structural evolution of such basins is important ... -
Structural geologic modeling and restoration using ensemble Kalman inversion
(Peer reviewed; Journal article, 2023-06)We demonstrate the use of Ensemble Kalman Inversion (EKI) for building three-dimensional, multi-fault, kinematically restorable structural geologic models, by means of a workflow in which fault geometry, the distribution ... -
A study of Machine Learning application on net-to-gross prediction using seismic horizons. Case Study: The Brent Group - Statfjord Field
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07-15)As petroleum geosciences enter the era of big data, this field of study encompass difficult optimization and decision-making in real-world problems. The increasing number, difficulty, and scale of such specific problems ... -
Study of Stress Concentration Factors at Pipe Welds in Relation to Hydrogen Induced Stress Cracking using Finite Element Method and Response Surface Modeling
(Master thesis, 2022)Duplex stainless steels, which are extensively used in the energy industry for subsea piping, have seen some significant failures, especially at the weld locations of cathodic protected piping components due to hydrogen ... -
(Sub)regional Hydrocarbon Potential in the Valanginian Mulichinco Formation in the North-Eastern Part of the Neuquén Basin
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07-13)Since the beginning of the 20th century, the Neuquén Basin has been the most important hydrocarbon producer in Argentina. Many different conventional plays have been explored and exploited, while, the unconventional ... -
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 ... -
Systematic atomic force microscopy and constraints for the determination of wettability and EOR research
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07)A highly attractive strategy within the hydrocarbon industry is improving the percentage of recovery from the reservoirs, called Improved Oil Recovery/Enhanced Oil Recovery (IOR/EOR). The Atomic Force Microscope (AFM) is ... -
