Trekantformede løsmasseskred: - Sammenligning av fire hendelser i Norge, betingelse for utløsning, løsneforhold og utvikling av skredet.
(Master thesis, 2015)I denne oppgaven er det sett på ulike trekantformede løsmasseskred, med deres utløsning og utvidelse nedover skredløpet. Skredene er valgt ut fra deres form på skredløpet og alle skredhendelsene skjedde i Møre og Romsdal. ... -
Triassic and Jurassic reservoir distribution influenced by Zechstein salt, in a normal fault system near the margins of the Utsira High, South Viking Graben, North Sea
(Master thesis, 2014)During the Triassic and Jurassic periods, structural and stratigraphic development in the margins of the Utsira High, in the South Viking Graben, resulted in the development of depressional mini-basins and the halokinesis ... -
Tube-wave monitoring as a method to detect shear modulus changes around boreholes: A case study
(Peer reviewed; Journal article, 2021)Monitoring the shear modulus of formations around boreholes is of interest for various applications, ranging from near-surface investigation to reservoir monitoring. Downhole logging tools and borehole seismic are common ... -
Tuning and Partial Saturation Effects on Reflection Responses at Sleipner Field
(Chapter, 2017)Calculating the normal incidence reflection responses of a stack of layers representing Utsira reservoir, we show that the seismic amplitudes are strongly affected by the partial saturation of CO2 and brine in the high ... -
Tuning Effect on Near and Far Offset Stacks: Mapping the Thickness Beneath Seismic Resolution of a Shallow Thin Layer in Block 2/4.
(Master thesis, 2014)Analysis of high-amplitude anomalies (bright spots) are the most used basic method of identifying hydrocarbon accumulations in seismic signals. When this method is applied to thin-bedded strata, the result can be misleading. ... -
Tunnel Finnsnes - Ingeniørgeologiske vurderinger: Spesiell fokus på mixed-face tunnel
(Master thesis, 2010)Dette prosjektet er skrevet som en master-/ diplomoppgave ved NTNU i Trondheim, som den avsluttende delen av forfatterens masterstudie. Masteroppgaven omhandler ingeniørgeologiske forhold ved en tunnel planlagt på Finnsnes, ... -
TUNNELING ASPECTS OF THE WATERWAY SYSTEM AND STABILITY ASSESSMENT OF THE POWERHOUSE CAVERN FOR THE MINAS-SAN FRANCISCO HPP
(Master thesis, 2018)The future trend of energy supplies is gradually moving from fossil fuels to renewable and sustainable energy sources. In this context, hydropower is one of the best options to supply the base load and meet the energy ... -
Tunnelling challenges in Nepal
(Chapter, 2004)Nepal is a landlocked mountainous country with a population of approximately 23 millions. Being steep in topography and having many rivers originating from the glaciers of the Himalaya, Nepal has been gifted in the field ... -
Turnkey Contract - A Management Challenge under Himalayan Geological Condition
(Journal article; Peer reviewed, 2016)Himalayan geology poses special attention and tunnelling challenges, which are associated to the engineering geological conditions in the rock mass. Completing tunnelling project within scheduled contractual time is an ... -
Two-Phase Flow Measurement
(Master thesis, 2010)The use of multiphase flow meters (MPFMs) increase each year. The main reasons for this are the cost benefits connected to the use of such a meter by eliminating exclusive lines to the test separator and the test separator ... -
Two-Phase Slug Flow Experiments with Viscous Liquids
(Doctoral thesis at NTNU;2016:109, Doctoral thesis, 2016)The challenges behind the multiphase transport of oil and gas mixtures are increasing as the oil and gas industry is moving towards production from non-conventional reservoirs and in remote locations. Transport of high ... -
Tynn tildekking av forurenset sediment: Småskala diffusjonsforsøk og modellering av diffusjon gjennom ulike dekklagsmaterialer
(Master thesis, 2008)Fire materialers evne til å redusere utlekking av miljøgiftene PAH og PCB fra forurenset sediment ved tynnsjikts tildekking, ble undersøkt. Materialene bestod av suspendert kalk fra Hustadmarmor, miljøgips fra NOAH, marin ... -
U-Pb geochronological and whole-rock geochemical analysis of the augen gneiss of the Dagvolsjøen Nappe, central Norwegian Caldedonides
(Master thesis, 2023)Øyegneisen i Dagvolsjødekket i de sentrale, norske Kaledonidene er dårlig kartlagt, og moderne geokronologi og geokjemi mangler fra typelokaliteten nær Brekken i Røros kommune. For å få en bedre forståelse av øyegneisen ... -
Ulriken tunnel - Stabilitetsanalyse av bergstabbe mellom tunnelløp ved TBM driving
(Master thesis, 2017)Eksisterende Ulriken tunnel i Bergen har nådd sin kapasitetsgrense og Bane NOR er i gang med utbygging av ny tunnel for etablering av dobbeltspor. I den forbindelse drives det 7,8 km TBM-tunnel parallelt med eksisterende ... -
Ulriken tunnel - Vurdering av ingeniørgeologiske utfordringer og behov for videre undersøkelser/oppfølging under TBM-driving
(Master thesis, 2015)Eksisterende Ulriken tunnel mellom Arna og Fløen har nådd sin kapasitetsgrense, og Jernbaneverket har bestemt å bygge en ny tunnel som skal ligge parallelt med og 30 meter sør for eksisterende tunnel. Tunnelen skal være ... -
Ultra Long Extended Reach Drilling
(Master thesis, 2010)With the notion of evolving current Extended Reach Drilling, this master thesis examines if drilling 20–40km is feasible. Several reservoirs offshore in the area outside of Lofoten in the northern part of Norway are reachable ... -
Ultrasonic Evaluation of Clay Behind Casing
(Master thesis, 2017)There's an increasing number of oil fields on the Norwegian continental shelf that will go out of production in the coming years, resulting in a big demand for permanent plugging and abandonment (P&A) services. There are ... -
Ultrasonic Evaluation of Well Integrity
(Master thesis, 2014)This thesis presents the acoustic theory behind current ultrasonic cement evaluation tools. The UltraSonic Imager tool's pulse echo technique and the new Isolation Scanner tool's pitch-catch leaky lamb wave measuring ... -
