Unsupervised Learning for Prostate Tumor Detection
(Master thesis, 2021)The detection of a lesion in the prostate can be a challenging task and is crucial for the early diagnosis of Prostate Cancer (PCa). Magnetic Resonance Imaging (MRI) examination provides a comfortable and precise solution ... -
Upper Jurassic to Lower Cretaceous source rocks in the Norwegian Barents Sea, part I: Organic geochemical, petrographic, and paleogeographic investigations.
(Peer reviewed; Journal article, 2021-09)This study provides a subregional to regional characterization of organofacies changes within the two members of the Upper Jurassic to Lower Cretaceous Hekkingen Formation (i.e. Alge and Krill) by integrating geochemical ... -
Upper Jurassic to Lower Cretaceous source rocks in the Norwegian Barents Sea, part II: Insights from open- and closed-system pyrolysis experiments
(Peer reviewed; Journal article, 2021-10)The petroleum generation potential of Upper Jurassic to Lower Cretaceous organic rich shales from the southwestern Barents Sea was evaluated using bulk and quantitative pyrolysis analysis. Fifteen thermally-immature samples ... -

Utilizing machine learning algorithms in the ensemble-based optimization (EnOpt) method for enhancing gradient estimation
(Master thesis, 2022)High or even prohibitive computational cost is one of the key limitations of robust optimization using the Ensemble-based Optimization (EnOpt) approach, especially when a computationally demanding forward model is involved ... -
Variation of the partition coefficient of phase-partitioning compounds between hydrocarbon and aqueous phases: an experimental study.
(Peer reviewed; Journal article, 2021)Many non-ionic chemical compounds will form real solutions in equilibrium between two immiscible phases in contact. The partition coefficient (K) is defined as the quotient between the equilibrium concentration of the ... -
A Visual Investigation of CO2 Convective Mixing in Water and Oil at the Pore Scale Using a Micromodel Apparatus at Reservoir Conditions
(Peer reviewed; Journal article, 2021-01)CO2 convective mixing in water has been visualized in Hele-Shaw and PVT cell experiments but not at the pore scale. Furthermore, CO2 convective mixing in a three-phase system (i.e., CO2 in the presence of both water and ... -
Visual investigation of CO2 dissolution and convection in heterogeneous porous media at reservoir temperature and pressure conditions
(Peer reviewed; Journal article, 2021)CO2 convective mixing in saline aquifers has been widely studied numerically and experimentally. Reservoir heterogeneity is significant for CO2 convective mixing and experimental studies are still limited. In this study, ... -
Water shut-off with polymer - core study application for the Alvheim Field
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)This thesis is an experimental study where different polymers have been evaluated for disproportionate permeability reduction (DPR) effects. The laboratory work was performed at Norce, for Aker BP, as a part of the Master’s ... -
Water Weakening of Artificially Fractured Chalk, Fracture Modification and Mineral Precipitation during Water Injection—An Experimental Study
(Peer reviewed; Journal article, 2022-05)This experiment was designed to study the water-weakening effect of artificially fractured chalk caused by the injection of different compositions of brines under reservoir conditions replicating giant hydrocarbon reservoirs ... -
Well monitoring from om-the-fly analysis of data from Permanent Downhole Gauges (PDGs)
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)The thesis focuses on time-lapse Pressure Transient Analysis (PTA) of data acquire with Permanent Downhole Gauges (PDGs). The objective is to develop and test approaches in automation of time-lapse PTA. Helping in providing ...
