  1. New Challenges in Deepwater Deepwater fields getting more complex: no single technology will “unlock” • 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

  2. Technology, Key to Ultra Deep Water Development 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

  3. Perdido System Layout Perdido 2 miles 8 miles 2.5 miles GREAT WHITE Host JV Partners: Shell (35%), Chevron (37.5%) , BP (27.5%)

  4. Subsea Layout under the Spar Subsea Boosting System Manifold Subsea Wells Flowline Sled

  5. Liquid Makeup oil Gas Top Tensioned Riser Subsea Boosting System • Host-scale subsea separation • Cyclonic flow to 35" x 320’ caissons • Liquids pumped w/ 1500 HP ESPs (25,000 bpd per ESP) • Free Gas flows through annulus • Umbilical Voltage = 4.4 KV

  6. Perdido – Night Shot
