Injecting CO2 raises pore pressure and this causes subsurface formations to deform. The pattern and amount of deformation will reflect the distribution of pressure and formation properties in the subsurface, two quantities of interest during CO2 storage. The hypothesis underlying this research is that the small deformation accompanying CO2 storage can be measured and interpreted to improve the storage process.
