UK CO2 – EOR Potential
Well proven tool in West Texas
4-12% of STOIIP extra recovery
Miscible and immiscible floods
Low quality, shallow (cool) reservoirs
1 billion barrels recovered to date
Untested in UK
Projected prize ~5% additional recovery
Largely miscible flood
High quality deep reservoirs
~ 3 billion barrels
− Matched by CO2 production

CO2-EOR Heritage
The CO2 production from eastern UK could ‘power’ CO2-EOR in the North Sea for 10-15 years per project, over ~30 year period
It could deliver: Improved security of oil supply
Infrastructure usable for carbon capture, transportation & storage
Increased tax revenues over current projections
Understanding of how storage sites behave
New & tested methodologies for MMV
Deep aquifer storage area
