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