Geological information is inherently uncertain!
• Engineers frequently design understandable equipment that can be iteratively interrogated
• Geologists and oil industry have to accept order of magnitude uncertainty and manage it appropriately…

• Can the subsurface store co2?– Natural analogues
• How similar is the oil industry?– Reservoir, seal, flow in porous media, multiphase
flow, well design, injection, production, imaging, transport, sub-sea infrastructure…
• Properties of CO2– Phase behaviour
– Multiphase flow
• How much can the earth safely store?– What does safely mean?
• What do we need to monitor? – Extent of CO2 plume?
– Pressure response?

Natural CO2 leakage
Sub-marineSub-aerial
Bubbles of liquid carbon dioxide rise from
the seafloor at the Champagne vent on
Eifuku volcano in the W Pacific.
The CO2 is liquid due to the high pressure.

Building confidence
• Studying natural analogues allows us to:
– Understand factors that increase security
– Understand why and how it leaks
– Understand impact of leakage
– Test monitoring strategies
