ϕ-OTDR/DAS enables dense, long-range (1 - 200 km), array recordings of strain fields with exceptional sensitivity ( < 1 × 10-9 strain) wherever optical fiber exists. The measurement is conventionally based on interferometrically extracting dynamic

Distributed acoustic sensing (DAS) is an emerging technology that repurposes a fiber-optic cable as a dense array of strain sensors. This technology repeatedly pings a fiber with laser pulses, measuring optical phase changes in Rayleigh backscattered

We compare the performance of a downhole distributed acoustic sensing (DAS) fiber-optic array with that of conventional geophones. The downhole collocated arrays are part of the Frontier Observatory for Research in Geothermal Energy (FORGE) geotherma
