Optimization Study of Seismic Monitoring Network at the CO2 Injection Site-Lessons Learnt from Monitoring Experiment at the Cranfield Site, Mississippi, U. S. A.

摘要

In this paper, we discuss the design (seismometers' types and layout) of seismic monitoring network that monitors microseismic events induced by CO2 injection and natural earthquakes that occurs around the CO2 injection site. We also elucidate CO2 injection and occurrences of microseismic events. Firstly, we tested a monitoring network at the Large-scale CO2 injection site in the U.S.A to obtain lessons learnt. Then, we review case studies of microseismic monitoring at the two CO2 injection sites. Finally, we discuss and propose the monitoring network that meets our requirements based on findings from the monitoring experiment and case studies.
