Tectonomagmatic Evolution of the Sveconorwegian Orogen: Insights from Geochemical and Isotopic Data
(Doctoral theses at NTNU;2022:123, Doctoral thesis, 2022)The Sveconorwegian orogen has a long, complex geological and tectonic history at the southwestern margin of the Fennoscandian Shield, which took place between 1140 and 920 Ma. For almost 150 million years of that time, ... -
Temperature Dependent Shale Strength and its Effect on Borehole Stability
(Master thesis, 2011)Borehole instability in shale has been a costly problem for the petroleum industry for years.The instability problems are related to the high complexity of shale in terms of mechanical and chemical properties. For instance ... -
Temperature History And Its Impact On AVO Responses In The Halten Terrace Area
(Master thesis, 2015)Temperature is a fundamentally important petroleum geology parameter affecting both i) reservoir quality preservation (diagenetic evolution) and ii) source rock maturation (hydrocarbon generation). The link between ... -
Testing and Verification of Well Barriers: Verifying cement plug using borehole seismic
(Master thesis, 2014)The aim of this thesis is to demonstrate how seismic waves propagate in wells, and to investigate the potential of using borehole seismic as an alternative to conventional cement plug verification. An alternative verification ... -
Testing of the Osmotic Membrane Pressure Actuator (OMPA) principle for autonomous water choking
(Master thesis, 2011)This Master thesis is a part of OMPA (Osmotic Membrane Pressure Actuator) which Is initiated andpatented by Statoil ASA Porsgrunn research centre at Feb. 27, 2007 (US). The objective of the OMPA project is to develop a ... -
Testing og evaluering av EVA-baserte sprøytbare membraner for permanent vanntett tunnelkledning med sprøytebetong for veg- og jernbanetunneler
(Master thesis, 2014)Det har oppstått et stort behov for å modernisere norske tunneler. Blant annet etterlyses det vann- og frostsikringsløsninger som skal ivareta moderne funksjonskrav. Masteroppgaven tar for seg permanent vanntett tunnelkledning ... -
Testing the use of acoustic emission sensors to detect in-situ hydraulic jacking
(Master thesis, 2021)I denne oppgaven ble akustiske emisjonsensorer brukt til å overvåke et hydraulisk splitting forsøk for å se om AE kunne brukes til å oppdage hydraulisk jekking (HJ) in-situ. Deretter ble det forsøkt å se hvilken forskjeller ... -
Testprogram for overskudds- og restmasser som planlegges brukt til tildekking av forurensede sedimenter
(Bioforsk Rapport;, Research report, 2006)Det er utarbeidet et testprogram for å vurdere egnethet av overskudds- og restmasser for bruk til tildekking av forurensede sedimenter. Testprogrammet vurderer materialets egnethet på generelt grunnlag, uavhengig av en ... -
The Beginning of the End: A Digital Planning of P&A Operations
(Master thesis, 2021)Som det er kjent, kan operasjoner for å plugge og forlate brønner være svært tidkrevende og kostbare. Slike operasjoner kan ha en kostnads tilsvarende den opprinnelige boreoperasjonen. Å etablere kostnadseffektive P & ... -
The contribution of maficultramafic mineral sources to magnetic anomalies
(Doctoral theses at NTNU;2019:210, Doctoral thesis, 2019)The interpretation of magnetic anomalies at all scales relies on the understanding of the petrophysical and rock magnetic properties. The stability of magnetic minerals in the crust depends on the composition and ... -
The controlling factors for runout lengths for “steinskred” in Hordaland, developing of a new α-β method for “steinskred” and analyses of the flow behavior “steinskred” event in Modalen, 1953
(Master thesis, 2021)Steinskred er en norsk betegnelse på et lite fjellskred eller et stort steinsprang. Denne faren er et velkjent fenomen i Norge, og kan forårsake katastrofale hendelser hvis den har rekkevidde som treffer hus eller annen ... -
The Cost Model of Subsea Production Systems and Flowlines including Automatic Flowline Routing
(Master thesis, 2020)Nowadays, optimization of field development projects in a cost-efficient way is one of the crucial topics in the petroleum industry. The current economic conditions and unpredictable fluctuations of oil price force all ... -
The Digital Coral: Infrastructuring Environmental Monitoring
(Journal article; Peer reviewed, 2015)Technologies for collaboration within the oil and gas industry, which are referred to as Integrated Operations, challenge traditional geographical, disciplinary, and organisational boundaries. Fuelled by the availability ... -
The Effect of Brine Composition and Rock Type on Oil Recovery by the Use of Combined Low-Salinity Waterflooding and Surfactant Flooding: A Literature Review and Experimental Study
(Master thesis, 2014)The possibility of achieving incremental oil recovery by the use of low salinity injection water has been demonstrated by numerous laboratory experiments and an increasing amount of field trials. The underlying mechanisms ... -
The effect of cuttings on annular pressure loss - An analysis of field data in the North Sea
(Master thesis, 2015)This master's thesis studies the correlation between rapid alterations in cuttings concentration and the corresponding change in pressure loss, using the standpipe pressure as pressure indicator. Drilling data from two ... -
The Effect of Field Pressure Interference: A Simulation Study on Aquifer Modeling and the Effect on Small Oil Fields from a Common Aquifer - Applied to Trell
(Master thesis, 2017)Petroleum reservoirs do sometimes communicate through a regional aquifer. This means that a pressure drop imposed in any of the fields is transmitted across the aquifer to the other fields, and manifested as pressure ... -
