Framework Factors with Critical Influence on Safety, Health and Environment in the Mining Industry
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:228, Doctoral thesis, 2012) -
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 ... -
Frequency-dependent wave velocities in sediments and sedimentary rocks
(Doctoral theses at NTNU;2022:52, Doctoral thesis, 2022) -
Frequency-dependent wave velocities in sediments and sedimentary rocks: Laboratory measurements and evidences
(Journal article; Peer reviewed, 2016)The pioneering work of Mike Batzle and his colleagues has provided a fundamental understanding of mechanisms behind dispersion and attenuation of elastic waves in fluid-saturated rocks. It also has made way for a realization ... -
Frequency-depth-dependent spherical reflection response from the sea surface - a transmission experiment
(Journal article; Peer reviewed, 2018)In academia and the industry, there is an increasing interest in generating and recording low seismic frequencies, which lead to better data quality, deeper signal penetration and can be important for full-waveform inversion. ... -
Freznel zone in VTI and orthorhombic media
(Journal article; Peer reviewed, 2017)The reflecting zone in the subsurface insonified by the first quarter of a wavelength and the portion of the reflecting surface involved in these reflections is called the Fresnel zone or first Fresnel zone. The horizontal ... -
Friction Factor Model and Interpretation of Real Time Data
(Master thesis, 2013)The interest in torque and drag issues has over the last years increased when the complexity of wells drilled has become higher. The petroleum industry continually expands the extended reach drilling envelope, which forces ... -
Friction Factors in Oil Wells through Analysis of Hook Load
(Master thesis, 2014)As the easy oil and gas is gone, there is today a need for more complex wells in orderto extract the remaining hydrocarbons. Over recent decades, both inclination andlength of drilled wells have increased significantly. ... -
Friction Reduction by using Nano-Fluids in Drilling
(Master thesis, 2014)The increasing requirements of drilling fluids in long extended reach wells desires for new solutions to solve torque and drag problems in the wellbore. Nanotechnology is an upcoming technology development, which is already ... -
Friction reduction by using nanoparticles in oil-based mud
(Master thesis, 2014)Nowadays, increasing demand on petroleum resources and depletion of easy accessible reservoirs result in exploration of challenging reservoirs. Drilling of deeper reservoirs is an important part of this challenge where ... -
Frictional fluid instabilities shaped by viscous forces
(Peer reviewed; Journal article, 2023)Multiphase flows involving granular materials are complex and prone to pattern formation caused by competing mechanical and hydrodynamic interactions. Here we study the interplay between granular bulldozing and the stabilising ... -
Frictional Pressure vs. Rheological Models
(Master thesis, 2010)When the drilling fluid leaves the mud pump, it circulates through the stand pipe, rotary hose, swivel, Kelly, drill pipe, drill collar, bit and the annulus between the drill string and the open hole or the casing. During ... -
From Caledonian collapse to North Sea Rift: The extended history of a metamorphic core complex
(Peer reviewed; Journal article, 2020)Extensional systems evolve through different stages due to changes in the rheological state of the lithosphere. It is crucial to distinguish ductile structures formed before and during rifting, as both cases have important ... -
From fossil to active hydrothermal outflow in the back-arc of the central Apennines (Zannone Island, Italy)
(Peer reviewed; Journal article, 2022)Post-orogenic back-arc magmatism is accompanied by hydrothermal ore deposits and mineralizations derived from mantle and crustal sources. We investigate Zannone Island (ZI), back-arc Tyrrhenian basin, Italy, to define the ... -
From Integrated Operations to Remote Operations: Socio-technical Challenge for the Oil and Gas Business
(Chapter, 2021)Remote operations started with integrated operations (IO) some years ago where designated tasks and roles were shifted from off- to onshore. Remote operations, however, is more than remote control as the operational model ... -
