DOI: 10.1016/j.fuel.2020.118948
Abstract: Abstract Harsh subsurface environments limit the robust workability of on-site instrumentation to be leveraged to track the Earth’s dynamics. Distributed fiber-optic sensing (DFOS) enables the long-period in-situ real-time detection of crustal geoenergy exploration-induced underground motions.… read more here.
