Experimental Studies and Modeling of Synthesis Gas Production and Fischer-Tropsch Synthesis
(Doktoravhandlinger ved NTNU, 1503-8181, Doctoral thesis, 2012)Indirect route can be used to convert abundant natural resources such as natural gas (NG), coal and biomass to synthetic fuels (referred to as gas-to-liquid (GTL), coalto- liquid (CTL) and biomass-to-liquid (BTL)). It is ... -
Experimental studies for carbonated injection water
(Master thesis, 2020)En av metodene for å redusere utslipp av drivhusgasser ved produksjon av olje og gass er å løse karbondioksid fra eksosgassen fra gass turbinene inn i rørledningen for injeksjonsvann hvor karbondioksidet vil bli permanent ... -
Experimental Studies in Interaction Design and Engineering Design Science - a Repository for Experimental Setups
(Chapter, 2016)This paper answers the design science‘s call for the systematical implementation of research methodology in order to empirically study the principles, practices and procedures of design. As a research methodology, experiments ... -
Experimental studies of a damaged ship section in beam sea waves
(Journal article; Peer reviewed, 2020)This work presents a series of experiments performed with a prismatic hull form in a small wave flume. The model is a midship section with rectangular damage opening on the side. It is slightly smaller than the flume breadth ... -
Experimental studies of a damaged ship section in forced heave motion
(Journal article; Peer reviewed, 2019)This work documents a detailed series of experiments performed in a wave flume on a thin walled prismatic hull form. The model consists of a rectangular opening located on the side. The length of the model is slightly ... -
Experimental Studies of Carbonated Injection Water
(Master thesis, 2021)Olje- og gassproduksjon er den største bidgragsyteren til Norges totale klimagassutslipp. Det betyr at det er et stort potensiale for utslippskutt. Dette kan løses ved å redusere produksjonen, men så lenge ... -
Experimental Studies of Hydrogen as a Fuel Additive in Internal Combustion Engines
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:35, Doctoral thesis, 2008)Combustion of hydrocarbons in internal combustion engines results in emissions that can be harmful both to human health and to the environment. Although the engine technology is improving, the emissions of NOx, PM and UHC ... -
Experimental Studies of Microbial Enhanced Oil Recovery
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:272, Doctoral thesis, 2012)The main purpose of this work was to understand the driving mechanisms by which the bacterium Rhodococcus sp. 094 increases oil recovery. The reason for only using this species was to thorougly investigate different aspects ... -
Experimental Studies of Stress Dependence,Static vs Dynamic behaviour and Mechanical Anisotropies of Shale
(Chapter, 2014)Laboratory data from controlled rock mechanical tests with various shales have been used to understand and quantify stress effects on wave velocities of relevance for 4D seismics, and to quantify the difference between ... -
Experimental Studies of the Acoustic Signal generated by Marine Seismic Sources
(Doctoral theses at NTNU;2019:80, Doctoral thesis, 2019)Marine seismic acquisition is the most commonly used geophysical technique to image the subsurface for different purposes, e.g. exploration of reservoirs or investigation of subduction zones as areas where earthquakes are ... -
Experimental studies of wave-ice interactions – insights into data analysis methods and their applications to studying the wave-induced responses of ice cover
(Doctoral theses at NTNU;2020:228, Doctoral thesis, 2020)Studies of wave-ice interactions include field and laboratory experiments, theoretical model developments, the implementation of these theoretical models in simulation tools, and the validation and calibration of these ... -
Experimental Studies on Municipal Solid Waste and Biomass Pyrolysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:125, Doctoral thesis, 2007)The introduction of this thesis (Chapters 1-9) presents the broader picture of waste management and thermal treatments (situation, trends and novel concepts) with a strong focus on nitrogen (N) in Chapter 6 (a summary of ... -
Experimental Studies on North Sea Rock Evaluating the Low Salinity Effect on Enhanced Oil Recovery and Permeability Reductions
(Master thesis, 2011)In this project the concept of low salinity water flooding is experimentally tested and discussed. Both the effect on enhanced oil recovery and the permeability reductions issues which can arise during low salinity flooding ... -
Experimental study and CFD simulation of water coning phenomenon in perforated geometry
(Master thesis, 2016)The focus of this thesis is to further examine the water coning phenomenon in annular geometry in a horizontal well completion. This phenomenon is of particular interest to the oil & gas industry, as it may restrict ... -
Experimental study and stress analysis of rock bolt anchorage performance
(Journal article; Peer reviewed, 2014)A new method was developed to apply pull-and-shear loads to the bolt specimen in order to evaluate the anchorage performance of the rebar bolt and the D-Bolt. In the tests, five displacing angles (0°, 20°, 40°, 60°, and ... -
Experimental Study for Wear Characteristics and Wear Prediction of Corrosion Resistant Alloy Material Tubulars
(Master thesis, 2022)Precise casing wear estimation is important to ensure appropriate well integrity and safer production of hydrocarbons. The amount of casing wear depends not only on operational parameters but also on the casing material. ... -
Experimental study into the overtopping and breaching of rockfill dams with erosion protection
(Master thesis, 2022)Embankment dams are mainly made of erodible and pervious materials and are at risk from overtopping and piping, the erosion process that initiates may ultimately lead to the dam breaching. Estimating the flood and mapping ... -
