In this paper, we investigate the relationship between surface deformation and microseismicity using coupled fluid-flow and geomechanical simulation. Since both microseismic and InSAR monitoring integrated with coupled fluid-flow/geomechanical modelling represent cost effective approaches in monitoring the containment of injected CO2, it is worthwhile exploring any potential link between microseismicity and surface deformation. Specifically, we simulate and examine the temporal and spatial evolution of microseismicity (see Angus et al., 2010) and surface uplift due to injection of CO2 for a faulted graben style sandstone reservoir model. We attempt to address whether there is a significant link between surface uplift and microseismicity, and if so, can we draw some relationship between rates of surface uplift and seismicity?
