5 Orbital Sea Surface Monitoring Brief history From R&D to operational use 1999 Oil seep detection project *Collaboration with INPE and NERSC 2000 Oil Spill detection project 2002 Fully integrated operational Service

6 Scope & Benefits Detection of oil slicks (seeps, spills) and ocean features on the sea surface using satellite surveillance Its benefits are The Link with PETROBRAS contingency response chain; Giving support in case of accidental spill; Providing routine monitoring of illegal discharges; Allowing the detection of oil seeps and pollution hot spots ; The development of statistics and customized algorithms image analysis, ancillary data integration; It is an important source of environmental information (meteooceanographic phenomena) In situ feedback guaranteed; Cost effective voluntary self-control activity.

7 Service Steps 1. Definition of coverage requirements (area of interest, frequency, NRT, etc); 2. Ordering of satellite data; 3. NRT image analysis; 4. Alerting and verification ; 5. Oil spill modelling; 6. Data dissemination.

8 PETROBRAS E&P Areas New (2009) Campos Basin Exploration Only 84% New (2009) Monitored Areas 95% of Brazilian oil & gas production

9 SAR Satellite data for Oil Detection Satellite in use: RADARSAT(1+2) - ScanSAR Wide and Narrow NRT (4-6 h) ENVISAT Wide Swath, VV (Only in specific events - needs ground station to be operational) CBERS (China-Brazil Earth Resource Satellite) - WFI Future : Cosmo-Skymed Others

10 NRT analysis Expert IMAGE INTERPRETATION - SAR low backscatter areas GIS DATA INTEGRATION to include ancillary information OCEANOP - PETROBRAS Operation Oceanography Service Meteo-oceanographic satellite data (AVHRR/NOAA, MODIS, QuikSCAT,.) Real Time METOC IN SITU data Updated offshore facilities location Planned E&P activities (drill steam tests, ship-to-ship off-loadings Vessels tracking systems (AIS and PETROBRAS/SGF)

12 Spill color and Appearance -> Oil thickness Spill location and size

13 Oil Spill modelling - Planning contingency actions V= 57 m 3 light crude oil 6/03 9/03 72 hs Model= OilMap, ASA

14 Data Dissemination All information (image files, METOC grids, spill vectors, geochemical results and verification feedback) is stored in a database. Intranet WebGIS Map Server ORBITAL MONITORING Geodatabase ArcGis Explorer Google Earth

15 Improvement & further developments: Cooperation with INPE: In Progress. - Multi-satellite receiving station in Cachoeira Paulista/SP ENVISAT and others (RADARSAT-2, COSMO, ); R&D Planned - Methods to derive METOC information from SAR; - Operational use of optical imagery for oil detection (MERIS HR, MODIS HR, CBERS, others ); - Ocean Color products; - SAR segmentation and classification methods.

16 Collaboration Opportunities On line monitoring of chemical, physical and biological data with IN SITU SENSORS Mangrove Areas assessment and monitoring Wind Energy Mapping

17 Collaboration Opportunities PIPELINE MONITORING - in progress Advanced detection of 3rd party encroachment Ground motion Oil spills Planning and building in remote areas Amazônia, Serra do Mar,. -Receiving station for VIS/NIR high resolution images -Change detection -Explore polarimetric and interferometric capabilities of SAR
