Baseline Microseismic Monitoring for CO2 Injection Sites

This submission describes a baseline passive seismic monitoring experiment for the Field Research Station in Alberta. The analysis does not reveal any local seismicity and we estimate a minimum magnitude (M) of detection of -1.4 for a source-station distance of 500m during quiet periods. Injection tests indicate that the detection threshold will rise to M=-0.1 during injection. Using perforation shots in the injection well we find the array is able to locate seismic events at the planned injection point to within 20m.
