6. Field Scale: Maureen Field for EOR/CO2 Storage
Maureen field – Preliminary study using Eclipse
Abandoned sandstone reservoir
413 million barrels (1.5x108 m3) oil
Simulate injection of CO2 after waterflooding
Oil Saturation

7. Maureen – Long Term Fate
How to contain CO2:
A) Dissolution CO2 dissolves in water
timescales 1000-year
B) Reaction carbonate precipitation
timescales 103 – 109 years
C) Trapping CO2 as pore scale droplets timescales decades surrounded by water

8. Maureen - Conclusions
CO2 and water injection increased oil recovery by 5-10%
This represents up to 1billion pound revenue from increased oil production while storing over 55 million tonnes of CO2
This is equivalent of all the CO2 produced from all activities from the population of London in a year
In the future, these strategies could be applied to other North Sea fields

82.5% CO2 can be trapped as an immobile phase
WAG injection for better sweep efficiency
