Abstract
An integrated hydro-mechanical assessment of the Ketzin pilot site for CO2 storage, Germany, has been carried out in the present study. For that purpose, history matched reservoir simulation models were coupled with regional-scale hydro-mechanical simulation models. Simulation results reveal maximum vertical displacements of about 6mm at the reservoir top and 4mm at the ground surface. Neither shear nor tensile failure is observed in the hydro-mechanical model at the end of the simulation time. Consequently, reservoir, caprock and fault integrity are maintained during the entire CO 2 storage operation. © 2014 Taylor & Francis Group, London.
