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 ... -
The effect of graphite filler in sample preparation for automated mineralogy – a preliminary study
(Journal article; Peer reviewed, 2018)Mineral particulate sample material is often prepared as polished sections for SEM based automated quantitative mineralogical analysis. A common practice is to mix ultra-pure graphite with sample material to avoid segregation ... -
The effect of nano-silica in oil-well cement
(Master thesis, 2013)A goal for all drilling operations is that they are performed within satisfactory safety- and financial boundaries. A big part of this is that the cementing operations are performed in a best possible manner, and having a ... -
The Effect of Salinity on Surfactant Flooding: A Literature Review and an Experimental Study
(Master thesis, 2013)Surfactant flooding is a proven EOR technique, which mobilizes residual oil by reducing interfacial tension (IFT). Several parameters affect the phase behaviour of a microemulsion system and a successful surfactant flooding ... -
The Effect of Small-Scale Heterogeneities on the Gas Distribution in the Tubåen Formation through Upscaling of CO2-Brine Relative Permeability
(Master thesis, 2017)The Tubåen Formation in the Norwegian Sea is an aquifer and was used by Statoil ASA as the injection reservoir for CO2 separated from produced gas at Snøhvit in the time period between April 2008 until it was abandoned in ... -
The effects of seismic anisotropy and upscaling on rock physics interpretation and AVO analysis
(Master thesis, 2015)In seismic reservior characterization, it is important that the measured sonic log used is accurate and consistent. Due to anisotropic effects in the reservoir, which is majorly caused as a results of interbedded sequence ... -
The effects of subsurface uncertainty on economic risk when developing the Mackerel satellite field in the North Sea
(Master thesis, 2019)Denne oppgaven undersøker effekten av usikkerhet i et lite Nordsjøfelt på om det er økonomisk forsvarlig å bygge det ut basert på produksjon, utvinningsgrad og endelig nåverdi (NPV) og internrente (IRR). To usikkerhetsfaktorer ... -
The engineering of petroleum streams
(Doctoral thesis, 2002)In a multidisciplinary petroleum industry using a wide variety of engineering software, consistent and easy transfer of quantitative data related to petroleum streams is a major issue. Making it more difficult is the lack ... -
