Use of Satellite Earth Observations, in situ data and numerical model capabilities for oil spill contingency Page 1
Oil spill service Page 2 Interest of Earth-Observation (EO) data for oil and gas companies => one example: oil spill service Based on EO data and satellite technologies, CLS offers a fully integrated service for: Oil spill detection Oil spill tracking Oil spill monitoring and forecasting
Combined approach Page 3 Satellite radar imagery to detect oil spills to assess their extents Drifting buoys (moored in the spill) to collect its location in real time to assess their locations Wind/current data and numerical models to describe metocean conditions to predict spills drift

Operational service: 2 modes Page 20 Surveillance (routine): Detection service only, based on radar imagery acquisition Low rate delivery (e.g. every week): of oil-spill reports over a specific area report is sent in near-real-time, i.e. couple of hours or less (depending on the area) after image acquisition Crisis (triggered in case of emergency): Combination of detection, tracking and forecast services High rate delivery (e.g. every day) of bulletins describing the oil spill situation and forecast
