Why All The Fuss Over Deepwater ?

• Large unexplored areas3D Seismic

It is an opportunity for large reserves and high flow rates

Technology is rapidly reducing the exploration cost and time

to first oil and cost.

Why all the planning?

But it is expensive

Specialized equipment is required for drilling anddevelopment

IT IS DEEP.
