(Master thesis, 2016)The oil industry is currently experiencing a very rough period where the need for constant new inventions, technologies, and an increase in earning and profit is greater than ever. In addition to exploring increasingly ... -
Systematic Study of Wettability Alteration of Glass Surfaces by Dichlorooctamethyltetrasiloxane Silanization - A Guide for Contact Angle Modification.
(Peer reviewed; Journal article, 2023)To investigate the effects of wettability on multiphase flow in porous media, glass bead packs or micromodels are commonly used. Their wettability can be altered by the surface treatment method–silanization. Although ... -
T-forbindelsen: Analyse av ingeniørgeologiske forhold knyttet til krysning av svakhetssoner i undersjøisk tunnel
(Master thesis, 2011)I perioden 2009 til 2013 bygges T-forbindelsen mellom kommunene Karmøy, Haugesund og Tysvær. Som del av dette prosjektet bygges Karmøytunnelen, en 8,9 kilometer lang undersjøisktunnel, under Karmsundet og Førresfjorden. ... -
TECHNICAL AND ECONOMICAL EVALUATION OF THE DELIQUIFICATION METHOD FOR GAS WELL(SS7) IN THE SONGO SONGO GAS FIELD
(Master thesis, 2017)This study was conducted to investigate the most suitable deliquification method for removing the accumulated liquid from the well SS7 to surface. This study began by determining different sources of liquid into the well ... -
Technical- and Comparative Analysis of Water- and Air Hammer Drilling in a Geothermal Environment
(Master thesis, 2014)Various methods of percussion drilling are investigated with an overall goal of delivering cheaper and better wells in the geothermal region Sebechleby. This thesis will focus primarily on the potential and limitations of ... -
Tectonic and sedimentary evolution of NE Greenland
(Master thesis, 2020)Due to thickness of the ice on Greenland region, seismic acquisition has been difficult in the past and few details have been published. Tectono-sedimentary evolution of NE Greenland basin is still not fully understood. A ... -
Tectonic control on the distribution of Upper Jurassic reservoir sands in the Statfjord-Gullfaks sub-basin
(Master thesis, 2019)Tektonikk representerer den viktigste faktoren som påvirker avsetning i et rift miljø. Fordelingen av øvre Jura reservoarsander i Statfjord-Gullfaks området ble sterkt kontrollert av utviklingen og sammenkoblingen av de ... -
Tectonic controls on accommodation in the southern Halten Terrace area, Mid-Norwegian margin.
(Master thesis, 2021)The Halten Terrace is located on the mid-Norwegian rifted margin and is bounded by basin bounding normal faults. On the eastern side, the Bremstein and Vingleia Fault Complexes (BVFC) constitute the most significant normal ... -
Tectono-sedimentary evolution of the eastern Forlandsundet Graben, Svalbard
(Peer reviewed; Journal article, 2021)The Forlandsundet Graben, situated along the NE Atlantic continental margin in the western Svalbard archipelago in Arctic Norway, represents a unique opportunity to study a basin that evolved along an obliquely rifted ... -
Tectonomagmatic Evolution of the Sveconorwegian Orogen: Insights from Geochemical and Isotopic Data
(Doctoral theses at NTNU;2022:123, Doctoral thesis, 2022)The Sveconorwegian orogen has a long, complex geological and tectonic history at the southwestern margin of the Fennoscandian Shield, which took place between 1140 and 920 Ma. For almost 150 million years of that time, ... -
Temperature Dependent Shale Strength and its Effect on Borehole Stability
(Master thesis, 2011)Borehole instability in shale has been a costly problem for the petroleum industry for years.The instability problems are related to the high complexity of shale in terms of mechanical and chemical properties. For instance ... -
Temperature History And Its Impact On AVO Responses In The Halten Terrace Area
(Master thesis, 2015)Temperature is a fundamentally important petroleum geology parameter affecting both i) reservoir quality preservation (diagenetic evolution) and ii) source rock maturation (hydrocarbon generation). The link between ... -
Testing and Verification of Well Barriers: Verifying cement plug using borehole seismic
(Master thesis, 2014)The aim of this thesis is to demonstrate how seismic waves propagate in wells, and to investigate the potential of using borehole seismic as an alternative to conventional cement plug verification. An alternative verification ... -
