State-of-the-art design guidelines in the use of unlined pressure tunnels / shafts for hydropower scheme
(Chapter, 2019)Technical soundness, cost effectiveness and long-term sustainability are the major issues that one should achieve while planning, designing, constructing and operating the hydropower schemes. With the changing world of ... -
Static and Dynamic Characterization of a Deep Overburden Shale
(Chapter, 2018)Since shales are the far most abundant overburden formation, understanding the geomechanical and rock physics behavior of shales is essential. We discuss a particular deep overburden shale in light of a thorough static and ... -
Static and dynamic stability analyses of the 800m high Åknes rock slope, western Norway
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:128, Doctoral thesis, 2008) -
Static and dynamic stiffness measurements with Opalinus Clay
(Journal article; Peer reviewed, 2018)In this work, an experimental study was carried out with the aim of reconciling static and dynamic stiffness of Opalinus Clay. The static and dynamic stiffness of core plugs from a shaly and a sandy facies of Opalinus Clay ... -
Statistical Analysis of MWD Aata in a Geometallurgical Perspective: A case study on an industrial mineral deposit
(Doctoral theses at NTNU;2019:191, Doctoral thesis, 2019) -
Statistical Analysis of Rheological characterization of Water-based Drilling Fluids
(Master thesis, 2017)Of fundamental importance in drilling technology is the drilling fluid. It has to counter varying wellbore conditions, and still be able to fulfil its objectives like suspension and transport of solids, pressure control ... -
A statistical mechanics framework for immiscible and incompressible two-phase flow in porous media
(Peer reviewed; Journal article, 2022)We construct a statistical mechanics for immiscible and incompressible two-phase flow in porous media under local steady-state conditions based on the Jaynes maximum entropy principle. A cluster entropy is assigned to our ... -
Steep Fracture Patterns And Their Characteristics Within The Triassic De Geerdalen Formation On Svalbard: An emphasis on regional trends, local variations and lithological controls
(Master thesis, 2013)This study documents and discusses the nature of steep fracture orientations, their densities and their relationships to lithological types, which has been observed within the Triassic De Geerdalen Formation on Svalbard. ... -
Strategies for Petroleum Exploration on the Basis of Bayesian Networks: A Case Study
(Journal article; Peer reviewed, 2014)The paper presents a new approach for modeling important geologicalelements, such as reservoir, trap, and source, in a unified statistical model.This joint modeling of these geological variables is useful for reliableprospect ... -
Strategisk dagbruddsplanlegging av en industrimineralforekomst
(Master thesis, 2022)Målet med denne oppgaven er å lage en 50-årig langsiktig dagbruddsplan i en industrimineralforekomst i Tromsdalen. Dagbruddsplanen lages ved å bruke direkte blokkplanlegging med programmet Miningmath. Gruveplanen må forholde ... -
Stratigraphy and palaeosol profiles of the Upper Triassic Isfjorden Member, Svalbard
(Peer reviewed; Journal article, 2022)The Isfjorden Member forms the upper part of the De Geerdalen Formation in Svalbard and is well exposed throughout central and eastern Spitsbergen, including the island of Wilhelmøya. We examine palaeosol profiles identified ... -
Stream Conversion Technology and Gas Condensate Field Development
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:120, Doctoral thesis, 2012)In the last few years, integrated modeling has become a preferred tool in the petroleum industry to manage the value chain of different assets. It is slowly replacing the traditional modeling approach that treats each ... -
Streamer depth versus vessel and seismic interference noise

Stress Induced Stability Assessment of the Underground Caverns for Moglicë Hydropower Project, Albania
(Master thesis, 2015)As a heavy investment to the Albanian renewable energy production, Devoll hydropower project (DHPP) is under development. DHPP is located in the southeast of Albania and consists of three hydropower plants, where Moglicë ... -
Stress Path Dependent Velocities in Shales: Impact on 4D Seismic Interpretation
(Journal article; Peer reviewed, 2018)Overburden stresses and pore pressure are altered by depletion or inflation of a subsurface reservoir, leading to seismic travel time and reflectivity changes that may be interpreted as footprints of reservoir drainage or ... -
Stress paths and predicted time-shifts around a depleting reservoir
(Chapter, 2020)Time-lapse (4D) seismic is an essential tool for monitoring the subsurface in and around producing hydrocarbon or CO2 storage reservoirs. The seismic time-shifts, in the reservoir as well as in the overburden, depend on ... -
Stress sensitivity of elastic wave velocities in granular media
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:45, Doctoral thesis, 2011)Knowledge of the stress sensitivity of elastic-wave velocities in sedimentary rocks with different consolidation is important for several geophysical applications such as seismic pore pressure prediction, time-lapse seismic ... -
Stress sensitivity of velocities in anisotropic rocks - Rock models comparison and true-triaxial apparatus description
(Master thesis, 2017)The purpose of this study was to investigate the effects of anisotropy on elastic parameters of rocks, and to compare various types of anisotropic rock models with the use of ultrasonic data obtained with a true-triaxial ... -
Stress-dependent elastic properties of shales—laboratory experiments at seismic and ultrasonic frequencies
(Journal article; Peer reviewed, 2018)Knowledge about the stress sensitivity of elastic properties and velocities of shales is important for the interpretation of seismic time-lapse data taken as part of reservoir and caprock surveillance of both unconventional ...
