What is it about?
Seismic exploration technologies with distributed acoustic sensing (DAS) are investigated to acquire seismic waves in high-temperature environments for eventually locating supercritical geothermal reservoirs deeper than the brittle-ductile transition boundary.

Why is it important?
We proved that deep DAS deployable in high-temperature environments can obtain reflection signals and natural earthquakes in geothermal fields to locate deep-situated structural anomalies.
Perspectives
The tolerable temperature of optic fiber systems would become higher beyond the critical point of water after technical development. The seismic and temperature observation as closest as possible to supercritical geothermal reservoirs would help understand the physical properties of the deep target in complex geological structures.
