Fiber-Optic Seismic Monitoring
Source: Dan HawkesTom Daley recently led a group of researchers (including ESD’s Barry Freifeld, Jonathan Ajo-Franklin, and Shan Dou) in a series of field tests examining the application of this methodology to borehole and surface measurements, focusing on the DAS data collected and the initial results from each test. Taken together, these tests, which were all part of CO2 storage monitoring pilots, demonstrated many potential applications of DAS technology, as well as some current limitations in sensitivity compared with conventional geophone recording.
