Analysis of petroleum oil droplet behavior during a subsea release
Sårheim, Synneva Christine (Master thesis, 2022)Under et undervannsutslipp flyter millioner av oljedråper gjennom vannkolonnen og opp mot havoverflaten. Hvordan dråpene oppfører seg når de når overflaten vil avgjøre både oljefilmtykkelsen, emulgeringen og livsløpet til ... -
Experimental and modeling study of subsea releases of oil and gas. - Oil behavior and effects in a cold or Arctic marine environment as a function of release conditions, oil chemistry and dispersant injection.
Dunnebier, Dorien Anna Engelbertha (Master thesis, 2015)Abstract With oil exploration going into deeper waters and more extreme environments, more detailed knowledge is needed about the fate of oil in case of a release. This thesis focuses on initial droplet formation, secondary ... -
Experimental and modelling study of subsea oil releases: focusing on small leaks from an aging oilfield off the Norwegian Continental Shelf
McKay, Rosalie Dawn (Master thesis, 2019)With advances in exploration and extraction technology, oilfields that would otherwise have been ready for decommission are expected to produce oil for many more years. While beneficial to extract as much resource as ... -
Kartlegging og kjemisk karakterisering av oljeforurensing langs Trøndelagskysten
Henriksen, Stine (Master thesis, 2012)Dette prosjektet omhandler identifikasjon av oljetyper i tjæreballer og oljeflekker funnet langs Trøndelagskysten. Prøvematerialet ble samlet inn på øyene Sula, Kunna, Vesterkalven, Storkalven og Aursøya langs Trøndelagskysten. ... -
Leaching of surfactants as a function of oil droplet size and surfactant properties. An approach using mass spectrometry and multivariate data analysis
Hansen, Sondre Kværne (Master thesis, 2017)Oil dispersants are used extensively in order to minimize the environmental damage that often follows an oil spill. A widely used dispersant, Corexit 9500A, consists of four surfactants with different properties and a ... -
Modelling of Subsurface Releases of Oil and Gas: Testing of a New Algorithm for Droplet Size Formation and Laboratory Verification
Lindersen, Peter Johan Bergh (Master thesis, 2013)The objective of the Master's thesis has been modelling of subsurface blowouts of oil and gas. The main objective was to the test a new algorithm for droplet size formation implemented into SINTEF's simulation tool ``Marine ... -
Oil spill forensics - Identification of possible sources for oil spills found along the coastline of mid-Norway - An experimental study combining GC-MS analysis and multivariate statistics.
Myrstad, Marie (Master thesis, 2016)This thesis aims to characterize 112 weathered oil samples collected on shore, at 18 islands, along the coastline of Mid-Norway during a time period of 2011-2015. Emphasis have been made on characterizing samples by three ... -
Oil Spill Forensics, investigating oil spill samples with GC-MS data with multivariate statistics and assessing the practical aspects of the free open source software R.
Espeland, Håkon (Master thesis, 2022)Dette arbeidet er utført på tidligere innsamlede data, med innføring av nye prøver hentet fra SINTEF's råoljelager. Dette antas å gi et bredt spekter av vitrede og uvitrede oljeprøver for å gi et variert utvalg av prøver ... -
Oil spill forensics: Identification of sources for oil spills by using data generated by GC-MS and ICP-MS combined with multivariate statistics and the COSIWeb database
Vike, Kristine (Master thesis, 2014)This work has been a preliminary study, aimed at investigating whether or not trace metal Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) analysis could be a viable tool in the oil spill investigation toolbox, after ... -
Releases of oily produced water from offshore installations - A combined laboratory and modelling study comparing resulting surface oil slicks and oil slicks detected by satellite
Wiken, Martin Andreas (Master thesis, 2021)Produsertvann er et biprodukt fra petroleumsindustrien som blir sett på som avfall, og blir ført opp til overflaten sammen med olje og gass. Etter at produsertvannet har gått gjennom nødvendige renseprosesser på oljeplattformen ... -
SubSea Dispersant lnjection (SSDI)- a "state of the art" and the need for further documentations
Daling, Per Snorre; Brakstad, Odd Gunnar; Brandvik, Per Johan; Davies, Emlyn J.; Grøsvik, Bjørn Einar; Meier, Sonnich; Nepstad, Raymond; Nordtug, Trond; Vikebø, Frode Bendiksen (;2017:00007 A, Research report, 2017)The aim of this pre-project has been to give a "State-of the art" and describe the R&D challenges and documentation needed in order to perform robust NEBA (Net Environmental Benefit Analysis) where SubSea Dispersant Injection ...
