Using Microseismicity to Estimate Formation Permeability for Geological Storage of CO2
Figure 1
Map views of event locations during hydraulic fracture stimulation for water (a) and CO2 (b) fluid injection. The locations of the injection well and monitoring array are also marked. Error bars represent one-standard-deviation errors based on arrival time residuals and particle motion analysis. As such, they do not account for the additional errors introduced by velocity model discrepancies (e.g., [18, 19]) and so should be considered a lower bound of the true location error.
