• The Stabroek Block covers 26,800 sq km containing multiple prospects and plays
• There are 20+ discoveries to date with 9 billion boe estimated recoverable resources
• Up to 10 VLCC-size FPSOs are expected to be required for full field development
• One FPSO is now in service: Liza Destiny with 120,000 b/d oil production capacity
• Two FPSOs are on order: Liza Unity and Prosperity, each with 220,000 b/d oil production capacity
• The procurement of fourth FPSO is being negotiated, a unit with 220,000 to 250,000 b/d oil production capacity
• There are plans for three to six more large capacity FPSOs to be contracted for Stabroek Block within this decade
• Nearby Blocks off Suriname are expected to require additional multiple FPSOs
