Tiltak for rensing av Killingdalområdet - En beskrivelse av forurensningssituasjonen og forslag til rensning
(Master thesis, 2017)Denne oppgaven beskriver forurensningsproblemene knyttet til Killingdal gruvers tidligere oppredningsanlegg i Trondheim. Dette anlegget produserte svovelkis fra sulfidholdig malm i perioden 1953- 1986. Både under drift og ... -
Time lapse seismic analysis of the Tohoku-Oki 2011 earthquake
(Journal article, 2019)A detailed time lapse seismic analysis of subsurface movements is presented using seismic 2D lines acquired prior to and after the Tohoku-Oki earthquake offshore Japan in 2011. Estimated movements of the seabed from the ... -
Time-dependent closure of a borehole in a viscoplastic rock
(Journal article; Peer reviewed, 2019)The paper describes a model to predict and analyze the time-dependent closure of a borehole drilled in a soft rock subjected to an initial isotropic stress, and the build-up of stress on a rigid casing after contact with ... -

Time-Domain Sensitivity Analysis Comparison of Two CSEM Methods
(Master thesis, 2019)Tidsdomene følsomheter av to forskjellige CSEM konfigurasjoner har blitt undersøkt og sammenlignet. Den første konfigurasjonen kombinerer vertikale kilder og vertikale mottakere, mens den andre ser på horisontale kilder ... -
Time-lapse interferometric imaging using an active source
(Master thesis, 2007)The purpose of time-lapse seismic processing is to relate changes in seismic signals to changes in reservoir parameters. A synthetic time-lapse experiment has been conducted in order to provide a controlled test environment ... -
Time-lapse Processing of 2D Seismic over the Japan Trench
(Master thesis, 2018)The seismic surveys SR97-101 (baseline) and D19 (monitor), acquired over the Japan Trench, were processed using an open-source software (Madagascar) with aims on detecting changes from the Tohoku-Oki earthquake. The surveys ... -
Time-Lapse Refraction Analysis Monitoring Shallow Gas Migration - 2/4-14 Blowout, A North Sea Case Study
(Master thesis, 2018)In January 1989, the drilling of well 2/4-14 situated in the North Sea took a dramatic turn of events when encountering a high-pressure zone. The well kicked and the situation eventually developed into an underground ... -
Time-lapse Seismic Analysis of the Tohoku Earthquake
(Master thesis, 2017)A time lapse seismic comparison of subsurface movements before and after the 2011 Tohoku earthquake is presented in this report. In order to successfully conduct this comparison, an entire processing sequence from raw data ... -
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
