The Application of Digital Completions and Fracture Data for the Validation of

Microseismic Observations.

Well Completions & Frac Database

1) Why we built it 2) How we built it 3) What is in the database 4) Validation of Microseismic 5) Observations & Conclusions

Used over 18,000 ISIP and leak-off test data points to derive: • MPS • Stress Gradient Maps • Effective Stress Ratio

Maps • Passive Boundary • Estimated Over Burden

Observations & Conclusions

We do see a correlation of Frac Data to Microseismic Hypo-centre Plots Where there are inconsistencies, other information may be required to better understand differences Require better information on Microseismic data to identify which completions have been monitored
