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
