(Master thesis, 2015)Nye Sulitjelma Gruver AS planlegger ny drift i Nordgruvefeltet i Sulitjelma, nærmere bestemt på den hittil uberørte Rupsi-forekomsten, på bunnen av Nedre Charlotta gruve og på forlengelsen av Giken-forekomsten. Til dette ... -
Forward Seismic Forward Modeling of an Outcrop Model from Kvalvågen on Spitsbergen: Investigating Thin Layers and Complex Geological Structures
(Master thesis, 2013)Using seismic modelling techinques to look at seismic resolution of complex and thin layered geological sturctures -
Forward Seismic Modeling: A Case Study from the Froan Basin and the Frøya High Area
(Master thesis, 2013)An extensive two-dimensional geological model was created to represent an offshore area in the mid-Norwegian Sea. The geological model was built based on a seismic line from the Froan Basin and the Frøya High area. Forward ... -
Forward Seismic Modelling of Volcanic Intrusions from Independence Fjord - Northeast Greenland
(Master thesis, 2013)The purpose of this thesis is to investigate the seismic response of large-scale volcanic intrusions by using the technique of forward seismic modelling. The modelled structures are exposed on the south side of Independence ... -
Fouling and clogging surveillance in open loop GSHP systems: A systematic procedure for fouling and clogging detection in the whole groundwater circuit
(Journal article; Peer reviewed, 2020)Fouling and clogging are some of the major water quality problems encountered in open loop ground source heat pump (GSHP) systems and aquifer thermal energy storage (ATES) systems. Here we present a surveillance strategy ... -
Fracture Assessment of Quasi-brittle Rock Simulated by Modified Discrete Element Method
(Journal article; Peer reviewed, 2020)New developments of an in-house hybrid code, named Modified Discrete Element Method (MDEM) are presented in the paper. The new developments are on the treatment of pre-existing and propagating fractures in quasi-brittle ... -
Fracture detection and analysis from image log raw data
(Master thesis, 2013)This report presents the results obtained during the master thesis done at NTNU in the department of applied geophysics and is part of the: ?Quantitative geology from petrophysical measurment? project.The goal of this ... -
Fracture Treatment Simulations Using a Modified Discrete Element Model (MDEM)
(Master thesis, 2016)Hydraulic fracturing is a widely used well-stimulation technique and one of the primary engineering tools for enhanced well productivity. To improve the understanding of how untouched rock mass reacts to stimulation, SINTEF ... -
Framework Factors with Critical Influence on Safety, Health and Environment in the Mining Industry

Framework for automated well planning and Digital Well Management
(Doctoral theses at NTNU;2020:357, Doctoral thesis, 2020)This research was initiated to establish mitigations of the performance gap in well construction. Expert representatives from each discipline spend on average 4,000 to 6,000 manhours of planning for each offshore well, ... -
A framework for evaluating deep sea mining systems for seafloor ma ssive sul phides deposits
(Doctoral theses at NTNU;2020:280, Doctoral thesis, 2020)Loki’s Castle, a SMS site of interest located in the Norwegian jurisdiction, was used to illustrate the established framework. The established economic block model was used to support a sensitivity analysis which shows ... -
Frå Nidarosen til Nidarneset: Ein ingegrert naturvitskapleg – arkeologisk – historisk rekonstruksjon av framveksten av Trondheim
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:65, Doctoral thesis, 2006)The centre of Trondheim is located on a peninsula at the mouth of Nidelva in the county of Sør-Trøndelag, Norway. A limited part of the town is an automatically protected heritage site Mellomalderbyen Trondheim (the medieval ... -
Free convection flow and heat transfer in pipe exposed to cooling
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:189, Doctoral thesis, 2010)One of the challenges with thermal insulation design in subsea equipment is to minimize the heat loss through cold spots during production shut down. Cold spots are system components where insulation is difficult to ... -
Frequency dependent elastic properties of shales – Impact of partial saturation and stress changes
(Doctoral theses at NTNU;2017:151, Doctoral thesis, 2017)Shales are the most common constituent of the overburden of conventional hydrocarbon reservoirs. As such, they have a strong influence on seismic waves and knowledge about overburden mechanical properties is required for ... -
