Abstract

Summary

Passive seismic monitoring projects should start with a survey design process. It is a de facto standard in all hydraulic fracturing monitoring, production monitoring, and carbon capture and storage monitoring, where microseismic activity is considered. The present study extends the previous study for distributed acoustic sensing (DAS) monitoring to estimate the uncertainty of event location and minimum magnitude sensitivity. DAS represents unique detectability compared to the geophone network, and it highlights the importance of dense array measurement with DAS. Our method explains the minimum magnitude in the real DAS measurement case study.
