Project Summary

A monitoring and verification program at the Surat CCS demonstration project must be able to distinguish natural variations in measured data with those that can be attributed to the CO2 storage reservoir. Monitoring data must be able to refute a hypothesis to draw rigorous conclusions about null signals This project is developing a robust modelling and predictive framework that can be applied to all components of a near-surface monitoring and verification program planned for the Surat CCS demonstration project. This statistical framework will allow measured anomalies to be attributed to leakage events if the data exceeds a specified threshold value. In response, an action plan detailing a mitigation strategy can then be implemented, in order to satisfy stakeholders.
