GLOBAL SEEPSOffshore Oil Slick DatabaseOil seep information is valuable to oil exploration companies for the detection and monitoring ofnatural seepage and oil pollution on the oceans surface.

Global Seeps is a non-exclusive database of offshore oil slicks, constructed by systematicallyscreening the world’s offshore basins. Global Seeps data is a cost-effective resource for risk-rankingprior to new exploration regions and for baseline oil pollution mapping.

Covering approximately 60 million km2 of offshore basins, the database is continuously updated.New areas are screened and existing areas are updated as part of a rolling programme and newacquisition can be programmed according to user request.

Key BenefitsDerived using both archive and newlyprogrammed satellite imagery, Global Seeps isthe definitive off-the-shelf offshore oil slickdatabase for the worldwide explorationindustry.

• worldwide dual coverage data

• accuracy - high resolution Synthetic ApertureRadar (SAR) data ensures all slicks arecaptured

• slick characterisation - identifying naturalseepage and man-made pollution

• scaleable and future proof – upgradedwithnew data and new areas

• availability – GIS-ready results delivereddirect to the customer

• Astrium can host the dataset making itavailable to multiple users across anorganisation using secure web access

Key Applications

• screening of frontier basins

• risk-ranking prior to new exploration

• obtaining spatial characteristics of the oilslick over areas of existing production

• planning surface geochemical programmes

• seismic planning and integration

• tool to link geological interpretation fromonshore to offshore

• environmental monitoring: environmental riskassessment, impact statement or fullenvironmental baseline

With more than 13,000 scenes directlyavailable, Global Seeps is a cost-effectivetool for risk-ranking in new explorationregions and for baseline oil pollutionmapping.

Data SpecificationThe database is delivered as a plug & go GIS product and is available on a local, regional orglobal license - it contains the following deliverables:

• scene interpretation results including scene outlines, metocean interpretation details, ship trafficand rig/platform information

• slick interpretation results including slick source points, slick vectors, probable slick type andconfidence levels

• digital geo-coded calibrated data for the full scene at 100-m resolution

• slick subset images at 25-m resolution

Global Seeps worlwide coverage - 13,000 scences covering approximately 60 million km2 of offshore basins

New - Near real-time tasking with rapid delivery of slick locations to vessels in the field

Astrium and GORE™ Surveys, based in the US, offer ajoint service involving near real-time satellite tasking andslick interpretation combined with geochemical samplingteams at sea using the GORE slick sampler kits.

Geochemical sampling of seepage slicks can add anotherlevel of information to this data, helping to add confidence& allowing a greater understanding of the nature of theseep. Slick locations are sent directly to the vesselsdirecting them to probable seepage slicks in order toobtain successful samples to validate and characterize thepetroleum system.
