Study on how oil type and weathering of crude oils affect interaction with sea ice and polyethylene skimmer material
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...
Dispersibility and biotransformation of oils with different properties in seawater
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...
Study of the oil interaction towards oil spill recovery skimmer material: Effect of the oil weathering and emulsification properties
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...
Interfacial properties of asphaltenes at toluene-water interfaces
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...
Subsurface oil releases – Experimental study of droplet distributions and different dispersant injection techniques Version 2
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...
Garantiana crude oil - properties and behavior at sea
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...
Brage crude oil - Properties and behavior at sea
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...
Sub-surface oil releases - Experimental study of droplet distributions and different dispersant injection techniques
Electrophoretic Measurements of Crude Oil Fractions Dispersed in Aqueous Solutions of Different Ionic Compositions-Evaluation of the Interfacial Charging Mechanisms
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...
