Abstract

Summary

The long-term safety of geologic carbon storage can be monitored using a variety of geophysical approaches. Monitoring CO migration in a geologic carbon storage site is generally carried out using the seismic method. In the present study, a seismic inversion based on simulated annealing is used to monitor CO migration, providing more detailed information. Seismic modeling can be used to image and monitor the fluid flow effects and leak detection in the reservoir. The Gassman fluid substitution was carried out to calculate the volume of the CO plume for the post-injection case. A 2D seismic model was generated to simulate the CO injection scenario. In the present study, synthetic data was used to check the reliability of the algorithm used in the case of the global optimization inversion technique. After performing the inversion analysis, a decrease in the impedance values is observed at the injection site. The inverted section shows very clear CO information which cannot be estimated from the interpretation of seismic data alone.
