Sammendrag
Phase 1: The basic physio-chemical properties of eight crude oils from the Statfjord oil field have been screened. Based on an overall evaluation of the results, two of the Statfjord crude oils were further selected to extend with a bench-scale weathering study (Phase 2). Phase2: A standardized weathering study has been conducted on SF Nord Brent (E-2&E- 3) and Sygna Brent (N-1&N-2) crude oils at 13 °C. Dispersibility testing included the dispersant Dasic Slickgone NS to estimate the viscosity limits and time window for dispersant use. The SINTEF Oil Weathering Model (OWM) was used to predict the weathering properties if the oils are spilled at sea. The weathering properties of the two oils were also discussed in relation to oil spill response.
