The interpretation of offshore seep data from SAR is affected by a number of geological, geochemical , environmental and SAR sampling parameters that make comparisons of basin seepage intensity difficult. To address this problem, we have incorporated relevant data from a new Global Basin Ranking Database to generate BLIMP, an ArcGIS-based basin leakage intensity map. This now factors in key information that will greatly improve the confidence of global seep interpretation.
The poster will review these key parameters which include
- geological affects (basin types, field sizes, seal integrity)
- geochemical affects (source rock type, age and maturity)
- environmental affects (wind speed, density layering and salinity)
- SAR sampling affects (weather compliancy and data volumes)
The result will be a complete revision of global offshore seepage patterns worldwide with a focus on three current exploration hot spots, the South Atlantic Margin basins of Brazil and West Africa, the East African Margin basins and the Circum Arctic basins
