Towards Bayesian Quantification of Permeability in Micro-scale Porous Structures – The Database of Micro Networks
(Journal article, 2020)This article develops a Bayesian framework to quantify the absolute permeability of water in a porous structure from the geometry and clustering parameters of its underlying pore-throat network. These parameters include ... -
Towards understanding the glacial impact on sedimentary basins using numerical methods
(Doctoral theses at NTNU;2016:297, Doctoral thesis, 2016)The Cenozoic tectonism and the Pleistocene glaciations had a strong impact on the sedimentary basins and petroleum systems of the Barents Sea. The impact of these processes are often considered together resulting in an ... -
Trace Element Study of Quartz from Nasafjell
(Master thesis, 2018)This thesis is written i cooperation with Elkem as a part of the High-Temp Quartz project, which is a joint effort between Elkem, Sintef and NTNU, with a goal to achieve a better understanding of quartz behaviour during ... -
Tracer-Based Two-Phase Upscaling
(Master thesis, 2019)Nøyaktig oppskalering av strømning i reservoar er et viktig tema i olje og gass industrien på grunn av de store beregningskostnadene assosiert med å utføre simuleringer på komplekse reservoarmodeller. Målet med en oppskalering ... -
Trajectory control, kick-detection and friction test: Transitioning to an automated drilling system.
(Master thesis, 2020)Denne masteroppgaven var originalt tiltenk å dekke Fase 2 av Drillbotics konkurransen. Dette ble endret som følge av COVID-19 utbruddet. Arbeidet utført i forkant av COVID-19 er vedlagt, slik at det kan videreformidles til ... -

Trap style characterization of the Paleocene Egga Member across the Ormen Lange Field Title - Subheading : Implications for Hydrocarbon volumetrics
(Master thesis, 2022)The Ormen Lange field is one of the largest gas reservoir offshore mid-Norway, developed as a combined structural-stratigraphic trap. The reservoir type consists of deep marine deposits of excellent quality with a facies ... -
Traveltimes for tilted TI media
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:311, Doctoral thesis, 2012)For many years, both the isotropic model and the transverse isotropic model with a vertical symmetry axis (VTI) were the standard in seismic modeling. These models are used to describe massive homogeneous sediments such ... -
Trekantformede løsmasseskred: - Sammenligning av fire hendelser i Norge, betingelse for utløsning, løsneforhold og utvikling av skredet.
(Master thesis, 2015)I denne oppgaven er det sett på ulike trekantformede løsmasseskred, med deres utløsning og utvidelse nedover skredløpet. Skredene er valgt ut fra deres form på skredløpet og alle skredhendelsene skjedde i Møre og Romsdal. ... -
Triassic and Jurassic reservoir distribution influenced by Zechstein salt, in a normal fault system near the margins of the Utsira High, South Viking Graben, North Sea
(Master thesis, 2014)During the Triassic and Jurassic periods, structural and stratigraphic development in the margins of the Utsira High, in the South Viking Graben, resulted in the development of depressional mini-basins and the halokinesis ... -
Tube-wave monitoring as a method to detect shear modulus changes around boreholes: A case study
(Peer reviewed; Journal article, 2021)Monitoring the shear modulus of formations around boreholes is of interest for various applications, ranging from near-surface investigation to reservoir monitoring. Downhole logging tools and borehole seismic are common ... -
Tuning and Partial Saturation Effects on Reflection Responses at Sleipner Field
(Chapter, 2017)Calculating the normal incidence reflection responses of a stack of layers representing Utsira reservoir, we show that the seismic amplitudes are strongly affected by the partial saturation of CO2 and brine in the high ... -
