A study of the weathering properties of the Søyla crude oil was performed as a bench scale laboratory study. The study included testing of dispersibility in addition to determining several chemical, physical and emulsifying properties of the oil. The obtained data was used as input in the SINTEF Oil Weathering Model (OWM), which was used to predict the behaviour of the crude oil in a spill situation at sea. A window of opportunity for use of chemical dispersants in a spill response scenario with søyla crude oil was established .. In this report, the weathering properties of Søyla crude oil are discussed in relation to oil spill response operations, particularly mechanical recovery and chemical dispersion.
