Architecture and Petroleum Systems of the Malvinas Basin, Argentina

Underlying Data

• 6315 km of proprietary Canesis seismic lines

• 1100 km of USGS seismic lines

• 2 boreholes with well logs

Holistic Interpretation

• Interpretation of basement and 5 key megasequences including source & accumulation rock from seismic data

• Structural lineaments interpreted from potential fields data

GIS Database and Seismic Interpretation Project

Product delivered in QGIS and OpendTect (also available in ArcGIS & Petrel)

OpendTect deliverables:

• 7400km of interpreted seismic data • 5 megasequences and source & accumulation rock

mapped as 3D horizons with thickness maps

QGIS deliverables:

• Structural and isopach maps in TWT and TVD domain• Interpreted publicly available potential fields data
