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
