Why All The Fuss Over Deepwater ? • Large unexplored areas 3D 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 and development


IT IS DEEP.
