Swelling pressures of some rocks using different test procedures
(Chapter, 2018)There are no clearly defined rules for the investigation procedures of swelling rocks. Difficulties are generally met for characterization and testing of swelling rocks and for prediction of the response to tunnel excavation. ... -
Synchronization of networked oscillators under nonlinear integral coupling
(Journal article; Peer reviewed, 2018)In this paper, we consider synchronization of dynamical systems interconnected via nonlinear integral coupling. Integral coupling allows one to achieve synchronization with lower interaction levels (coupling gains) than ... -
Synkinematic intrusion of granitoid sheets, with implications for molybdenite deposits in the Knaben Zone - Sirdal Magmatic Belt, SW Norway
(Master thesis, 2015)The Knaben Zone represents a N-S-elongated zone with abundant xenolith screens and molybdenite deposits within the late Mesoproterozoic Sirdal Magmatic Belt (SMB) batholith in the Sveconorwegian orogen, in SW Norway. The ... -
Syntactic Foam as Mitigation against Thermally Induced Trapped Annulus Pressures on the Linnorm field
(Master thesis, 2013)An investigation on the feasibility of a crushable foamwrap productfor mitigation of annulus pressure buildup on the Linnorm projecthave been performed. Several different aspects of this technology havebeen investigated, ... -
System and method for estimation of drill cuttings concentration in a borehole
(Master thesis, 2015)Faster and cheaper wells are important to increase the recovery factor from producing fields and for making marginal fields profitable. Hole cleaning is a time consuming non-productive operation which increases well cost. ... -
System Design for the Next Generation Subsea IMR Vehicles
(Doctoral theses at NTNU;2018:196, Doctoral thesis, 2018)This thesis is about how to unlock the full potential of unmanned underwater vehicles to save cost and increase quality in inspection maintenance and repair (IMR) services for subsea petroleum extraction equipment. Today ... -
System for Control of Downhole Pressure During Drill Pipe Connection - A Potential Method for Compensating of Pressure Variation in a Borehole
(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, ... -
