North Sea Central Graben Pressure Study Phase 2

Phase 2 of this study was completed in 2011, and it enhances the North Sea Central Graben Pressure Study Phase 1 by integrating full 3D seismic coverage to supply:

• Better definition of pressure compartments
• Evidence for fluid escape in and around breached traps
• Structural definition relative to well position and the location of seal failure

The maps in this study are based on data released up to 2009, and include:

• An effective stress map to show areas of potential seal breach
• New definition of Jurassic/Triassic pressure compartments

Phase 2 is a complementary study and does not replicate the five case studies of Phase 1.
