Regional pressure management of storage
• 360 Mt CO2 does not connect, but the pressure waves do. • 2 x 6 Mt/yr x 30 yr, pressure moves down and sideways • Open underburden boundary, increases storage by 20% in 30yr life • Understanding connections ensures Site B is not damaged by Site A • Regulators and Developers need to share information more than h/c
