Understanding the fate of spilled oil in cold environments is essential for oil spill response in Arctic areas. The potential for oils to adhere to sea ice and mechanical skimmers can significantly impact the success of oil spill response and influence the fate of oil in the marine environment...
Dispersants are used to remove oils slicks from sea surfaces and to generate small oil-droplet dispersions, which may result in enhanced biodegradation of the oil. In this study, dispersibility and biodegradation of chemically dispersed oils with different physical-chemical properties (paraffinic...
The primary aim of this research was to identify the physicochemical properties of the oil and water-in-oil (W/O) emulsions used during a NOFO Oil-on-Water field trials that reduced the performance of the skimmers recovery efficacy during the trials. Extensive studies were performed at SINTEF...
Asphaltenes are “n-alkane insoluble” species in crude oil that stabilize water-in-oil emulsions. To understand asphaltene adsorption mechanisms at oil–water interfaces and coalescence blockage, we first studied the behavior in aliphatic oil–water systems in which asphaltenes are almost insoluble...
The main objectives with this project have been to answer the following questions regarding dispersant injection during a subsea blowout. How do dispersant injection method, dispersant to oil ratio (DOR) and dispersant type affect oil droplet size (Volume Median Diameter – VMD)? How does the...
A small and meso-scale study of the weathering properties of Garantiana crude oil has been performed at 5°C and 13°C in SINTEFs laboratory. The data are used as input for SINTEF's Oil Weathering Model (OWM) to predict the properties and behaviour of the Garantiana crude oil in a spill situation at...
A study of the weathering properties of Brage crude oil has been performed at 5°C and 13°C in small-scale laboratory testing. The data are used as input to SINTEF Oil Weathering Modell (OWM) to predict the behaviour of Brage in a spill situation at sea. The weathering properties are discussed...
Electrophoretic measurements were carried out as a function of pH for various fractions of an acidic crude oil dispersed in pure water and low salinity solutions of NaCl and CaCl2. The acidic and basic components were selectively extracted from the crude oil in order to elucidate their importance...
