Brazil seepage study Offshore Brazil has already been covered by NPA’s satellite seepage detection project. Seepage detection by SAR (Synthetic Aperture Radar) is a proven technique for mapping surface oil seeps which could provide the first indication of petroleum systems in these basins:

• 281 interpreted SAR scenes over offshore blocks in Brazil’s 15th licensing round blocks

• This provides over 10 times coverage in most areas, with new data being sourced over areas of sparser coverage

BackgroundBrazil’s 15th licensing round offers an interesting mix of basins; from those with no discoveries (e.g. Pernambuco-Paraiba) to shallow water extensions of prolific basins (e.g. Campos) to slope and deepwater parts of basins with existing but more moderate reserves (e.g. Espirito Santo, Sergipe Alagaos).

The results of the NPA SAR seepage study hold value in all these basin settings, particularly in underexplored or frontier basins, such as in the Pernambuco-Paraiba Basin, where there is the possibility of defining a potential oil kitchen. Furthermore, any indication of a proximal extension of the Campos Basin petroleum system, away from the established, but less leaky, pre-salt play-fairway, will be of value. Indications of an oil play in the deepwater extension of the Sergipe-Alagoas Basin charge may also be revealed by this study.

NPA are currently increasing coverage levels of satellite data offshore Brazil, which could potentially uncover temporal repetition over existing slicks or discover new sites of possible seepage. This key information for offshore Brazil is now available from NPA.

NPA offer the Global Offshore Seeps Database (GOSD), as the main component of its Seep Explorer onshore and offshore seeps product suite. Hydrocarbon seep detection from satellite imaging maps the location and repeatability of naturally occurring oil seepage offshore. GOSD is a recognized and valuable tool for New Ventures & Exploration teams and has been adopted by the majority of the major international oil companies.

Global offshore seep database

• >30,000 satellite radar images interpreted for natural oil seepage, >220,000 slicks recorded

• Optimal satellite SAR data selected from weather screening of the world’s SAR archives

• Multiple coverage - up to 10x coverage becoming standard

• Data integrated and interpreted with supporting Robertson geological, geophysical and geochemical data, where available

• New high-resolution data from TerraSAR-X, Radarsat-2 and Cosmo Skymed satellites used for license studies

Deliverables

• Full ArcGIS* deliverables and custom ArcGIS toolbar enhancing results visualization

• Results overlaid and compared to collateral data layers including: bathymetry, gravity, sedimentary thickness, magnetics, shipping lanes and ship wrecks

• Online webserving enables content to be viewed by all approved users

Additional unique features

• Seepage intensity maps - related to basin leakiness parameters

• Seep data accessible via the Robertson Basins & Plays geological database

• Complete CGG validation chain - Seeps - Multibeam - Drop Cores - Geochemistry
