Modell for casing design
(Master thesis, 2015)Foringsrørdesign er utført for å evaluere alle mulige hendelser en brønn kan bli utsatt for. Foringsrørene må tåle lastene, temperaturene og slitasjen den kan bli utsatt for i løpet av brønnens levetid. For å godkjenne et ... -
Modellbasert berginjeksjon - Utforskning, vurdering og bruk av modeller for berginjeksjon
(Master thesis, 2018)Denne oppgaven beskriver teorien til injeksjonsmodellene Grout Intensity Number og Real Time Grouting Control. Det er utført et forsøk for å teste Real Time Grouting Controls evne til å beskrive injeksjon. Forsøket fant ... -
Modellering av grunnvannsstrømning i SEEP/W ved tunneldriving
(Master thesis, 2022)For at et tunnelprosjekt skal være vellykket forutsetter det at ytre miljø ikke blir påvirket i nevneverdig grad av tunneldrivingen. Grunnvann som siver inn i tunnelen kan redusere poretrykket og grunnvannsnivået over store ... -
Modellering av YPL Fluid Strømning i Eksentrisk Annulus med Borestrengsrotasjon
(Master thesis, 2012)Denne oppgaven omhandler teoretisk modellering av trykktap grunnet rotasjon i eksentriske borehull med Herschel-Bulkley strømning. En eksisterende modell for trykktap for konsentriske borehull ble videreført til å inkorporere ... -
Modelling acoustic pressure of very shallow airguns.
(Master thesis, 2022)A surge of advancements in air-gun technologies propels geophysicists to ask the uncomfortable question. Is there an alternative to equipment-based low-frequency enhancement? Most marine seismic acquisition setups are ... -
Modelling and Analysis of Autonomous Inflow Control Devices
(Master thesis, 2017)Gas and water coning is a significant problem in many oil fields. Inflow control technology is used to limit the negative effects of coning, and newer technology is regularly introduced. This thesis investigates Autonomous ... -
Modelling and Experimental Study on the Production of Gas Wells with Associated Liquid
(Doctoral theses at NTNU;2020:340, Doctoral thesis, 2020)Once a gas field is developed liquid production may start and persists sometime during the production life of most dry gas wells. This liquid could be condensate, water, or both, resulting from condensate dropout due to ... -
Modelling and Interpretation of Marine Controlled Source Electromagnetic Data
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:229, Doctoral thesis, 2009)This thesis aims to (i) interpret the marine CSEM data acquired over offshore Angola, Modgunn arch in the Norwegian Sea and Troll West Gas Providence (TWGP), offshore Norway, (ii) evaluate the effects of acquisition ... -
Modelling Geophysical Properties of Crustal Igneous Rocks
(Master thesis, 2017)The chemical composition of crustal igneous rocks strongly affects their geophysical properties. In order to model these effects, a classification scheme based on silica content was applied, resulting in the classes felsic, ... -
Modelling Medium- Depth CO2 Injection at the Svelvik CO2 Field Laboratory in Norway
(Master thesis, 2018)The CO2 Field Lab is a test site at the Svelvik ridge near Oslo in Norway. It is presently being upgraded as part of the European research infrastructure initiative (the ECCSEL laboratories). The test site was established ... -
Modelling of Carbon Dioxide transport in pipelines and wells for Carbon Capture and Storage(CCS) applications using Python
(Master thesis, 2024)Mastergraden fokuserer på modellering av karbondioxidtransport i rørledning og brønn, for bruk innen karbonfangst og lagring. Python er benyttet som modelleringsverktøy. Hovedmålene til oppgaven er å utvikle en modell for ... -
Modelling of dispersed oil/water flow in a near-horizontal pipe
(Journal article; Peer reviewed, 2022)A gravity-diffusion model was implemented for predicting water concentration profiles in dispersed oil-continuous oil–water flows. In this model, the measured droplet size distributions were used instead of a droplet size ... -
Modelling of Paraffin Wax in Oil Pipelines
(Master thesis, 2012)As warm oil or condensate from the reservoir flow through a pipeline on the cold sea bottom, wax often precipitate and deposit on the wall. To predict the rate of the deposition, wax modeling is important. The main mechanism ... -
Modelling of Surface Hook Load Signals when Tripping Out of Hole
(Master thesis, 2013)World demand for oil and natural gas are increasing, at the same time as most easyaccessible oil are being drained. Therefore, more complex and longer extendedreachwells (ERD) are required by the petroleum industry. The ... -
Modelling of the Transient Pressure Build-up in Long Wellbores
(Master thesis, 2015)Drilling of long oil wells becomes increasingly more common in the oil and gas industry, as cost rises and complexity of undrilled reservoirs increases. This introduces a challenge that grow in severity with the length of ... -
Modelling organic carbon distribution influenced by the presence of an oxygen minimum zone
(Master thesis, 2013)The processes for the preservation of organic carbon in deposited sediment over geologic time have been a source of debate over the years. Several studies have been carried out on the topic; some studies indicate anoxia ... -
