Petrobras and Pemex assess deep pre-salt drilling offshore Mexico
Petrobras and Pemex are assessing seismic and geological data for a high-risk effort to unlock deeply buried Jurassic crude in offshore Mexico’s pre-salt formations. The plan faces major drilling challenges through unstable, high-pressure salt. Petrobras would try to replicate its pre-salt experience from Brazil, while also exploring below other deepwater sediments and younger salt layers.
