CO2 Leakage Risk [Fault Data]

1. Whether ‘Fault Data’ remain to be biased? & Are they get influenced by the concerned method, as Faults are studied @ different scales and by different methods?

2. Do we have enough Data Available from Fault Properties with reference to Fault Geometry?

3. Whether existing approaches – used for analyzing ‘Fault Seal Integrity’ remain to be sufficient enough, or do they have serious limitations?

4. If the aquifer has multiple zones and if it has numerous faults forming drainage segments with varying connectivity, how best could we monitor CO2 leakage in the long run (following CO2 injection)?

5. In the context of Seismic Fault Interpretation associated with 3D Structural Geo-modelling, although the development of ‘Automated Fault Interpretation’ tool based on AI & ML tend to reduce interpretation time, are we efficiently making use of this ‘saved time’ towards effective ‘Fault Analysis’ (geometry/truncations) & ‘Fault Integration’ to Stratigraphy (throw analysis/growth faulting/reactivation/fault seal evaluation)?
