Alaska CO2 Storage Options

• EOR : Viscous Oil• 15 billion barrels oil in place

• Recovery Factor = 0-20% w/o EOR

• Recovery Factor = 30% with CO2 EOR

• Deep Saline Formation (ie Ivishak)

• Depleted Oil Reservoirs

• Gas Hydrates

• Coal Beds

Why CO2 Capture & Storage in Alaska ?

• Unlock Viscous Oil Production• Unlock Gas Commercialization• Big Sources : Large Turbine Emissions • Good Sinks : Viscous Oil

• Onshore : significantly cheaper than offshore

• Arctic : significantly impacted by climate change

• Mature CO2 capture options
