Oil seep information is valuable to oil exploration companies for the detection and monitoring of natural seepage and oil pollution on the oceans surface.
With over 20 years experience carrying out offshore projects for the oil and gas industries, Airbus Defence & Space has interpreted over 13,000 satellite scenes for the purpose of mapping natural oil slicks for the Global Seeps database.
Global Seeps is a non-exclusive database of offshore oil slicks, constructed by systematically screening satellite data over offshore basins, using a wide range of archive and newly programmed satellite data.
The database contains over 14,000 potential seepage slicks identified, including slick source points, slick vectors, probable slick type and confidence levels.
All data is immediately available on a local, regional or global licence and new acquisition can be programmed according to user request.
Individual country/basin studies derived from this data are available for purchase off-the-shelf with project deliverables ready for immediate delivery. New areas are screened and existing areas are updated as part of the rolling Global Seeps programme and new acquisition can be programmed according to user request.

Repeat slick mapped on 6 dates of imagery
Oil Slick Detection
Global Seeps screening uses satellite data acquired over the ocean to detect any oil slicks that may be present on the sea surface. The imagery is interpreted to identify slicks which may be sourced from natural seepage from hydrocarbon reserves.
When oil leaks from a reservoir under the sea floor, small oil coated gas bubbles travel up through the water column to the sea surface, where they form a very thin film on the water. This film can then be detected on satellite imagery and mapped, providing the data is collected under the correct weather and ocean conditions.
To ensure the quality of the Global Seeps results, all imagery used is extensively screened for weather compliancy and a minimum of two dates of imagery per scene footprint is acquired for all offshore areas. Using at least two image dates helps to increase the confidence of each feature found as well as pinpoint source points for multi-date seeps.
