Time-shift analysis in the overburden and reservoir zones from 4D studies across the Norne field
(Master thesis, 2019)4D seismic is a powerful tool, mainly used for monitoring the changes in the reservoir and overburden zones that might occur due to hydrocarbon production or EOR-related changes. The observed changes on 4D seismic can be ... -
A Timelapse Development of the Levant Basin since the Early Pliocene - Documenting the Seismic Geomorphology and Stratigraphy of Depositional Elements
(Master thesis, 2017)Investigation of the seismic geomorphology of the overburden in the southeastern Levant Basin -
Timing and Mechanism of magmatic sill emplacement in the Vøring Basin, Norwegian Sea
(Master thesis, 2017)The Cretaceous sediments of the Vøring Basin, Norwegian Sea, are locally intruded by sever-al igneous sills, which are mainly Doleritic. 12 magmatic sills were interpreted in the on high resolution 3D seismic data, together ... -
Tomographic inversion using 4D seismic data
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:335, Doctoral thesis, 2012)Time-lapse (or 4D) seismic data has become an acknowledged technique used to monitor the development of subsurface reservoirs due to human interaction such as production of hydrocarbons or injection of CO2 for storage ... -
Top hole drilling in deep water
(Master thesis, 2010)Summary When drilling the top hole section in deep water regions, alternative methods to the conventional riserless drilling system may be employed to avoid the "Pump and Dump" strategy. Conventional drilling with riser ... -
Topics in Production Systems Modeling: Separation, Pumping and Model Based Optimization
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:180, Doctoral thesis, 2014)This thesis addresses three distinct topics within oilfield production technology: 1) Inline oil-water separation for subsea applications, 2) Model based constrained optimization for production networks of high water cut ... -
Topics on Integrated Asset Modelling, Production Systems Boosting and Virtual Metering
(Doctoral thesis at NTNU;2015:293, Doctoral thesis, 2015)This thesis addresses four existing gaps and missing facilities in the route to improve the capabilities to model an entire oil and gas field extending from the reservoir to the field sales point. Such a model, referred ... -
Topographic Effect in the Selection of Unlined Pressure Tunnels / Shafts - A Review of a case from Nepal Himalaya
(Chapter, 2017)The design principle behind unlined pressure tunnels/shafts is that the minimum principle stress should be higher than the hydrostatic head acting on the periphery of tunnel/shaft. So, reliable estimation of in-situ stresses ... -
A topographic hinge-zone divides coastal and inland ice dynamic regimes in East Antarctica
(Peer reviewed; Journal article, 2023)The impact of late Cenozoic climate on the East Antarctic Ice Sheet is uncertain. Poorly constrained patterns of relative ice thinning and thickening impair the reconstruction of past ice-sheet dynamics and global sea-level ... -
Toward Green Flotation: Interaction of a Sophorolipid Biosurfactant with a Copper Sulfide
(Peer reviewed; Journal article, 2020)The United Nations’ Sustainable Development Goals have sparked growing interest in biosurfactants from many surfactant-loaded industries including those utilizing froth flotation for mineral separation. However, the ... -
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 ... -
