New Challenges in Deepwater
• Ultra-deep water and remote locations
• Harsh environments
• Small and/or sub-economic accumulations • Viscous oil, low energy drive and lift • High cost drilling & infrastructure
• Lack of local logistics / service industry

Deepwater fields getting more complex:
no single technology will “unlock”
Perdido Key Features
• Deepest spar in world
• Spar capacity100k bopd, 200 mmscfpd, and 80k bwip
• 150-person accommodations
• Doubles our water depth capability for a platform drilling system
• 35 wells (22 DVA subsea, 13 remote subsea)
• Deepest subsea production in world
• Gas and liquid separated at seafloor and pumped with electric submersible pumps (ESP’s)
• Oil (77 miles) and gas (107 miles) export pipelines
