Summary:
Carbon capture and storage (CCS) represents a key technology, allowing us to continue fossil fuel usage while mitigating greenhouse gas emissions. For CCS to be viable, operators must demonstrate that CO2 can be trapped in subsurface layers for thousands of years. A key issue for storage integrity is the geomechancal response of the reservoir. Operators must therefore be able to demonstrate an understanding of the geomechanical effects of CO2 injection. In this paper we consider several large-scale CCS sites, and compare and contrast their geomechanical responses. We also assess how geomechanical deformation has been imaged at these sites, the modelling techniques used, and how models and observations can be linked.
