Description:
In the joint project PROTECT (PRediction Of deformation To Ensure Carbon Traps) we predicted and quantified the distribution and the amount of sub-/seismic strain in the proximity of the CO2 reservoir in the Otway Basin. Three approaches fill the sub-seismic space: seismic multi-attributes stabilized the interpretation of the 3-D depth model by imaging small lineaments; retro-deformation revealed in the seal ca. 3 % as highest strain magnitudes; numerical forward modelling shows that the minimum horizontal stress at reservoir is locally overprinted by faults. We calibrated our predictions with new near-surface reflection seismic measurements and used advanced visualization tools. Thus, this seismo-mechanical workflow reveals possible migration pathways, and as such provides a tool for prediction and adapted time-dependent monitoring for subsurface storage in general.
