What was discovered
Discovery of vast oil reservoirs beneath a 2 km salt layer, more than 5 km below the sea and about 300 km offshore. It required developing drilling and production techniques in ultra-deep water.
The well was drilled in 2006 and the find announced in November 2007; earlier sub-salt crude in the Gulf of Mexico and West Africa was not of this magnitude.
What it led to
- Increased Brazilian oil production
- Ultra-deepwater drilling technology
- A new legal framework for sharing oil revenue
