Sisprobe is happy to announce that it has started work on yet another passive seismic dataset recorded in an earthen dam wall – this time from an experimental dam site.

Vattenfall AB funded the construction of this experimental-scale earth embankment dam, at its laboratory facilities in Älvkarleby, Sweden. The data has been recorded using fibre-optic cables with Silixa’s class-leading Distributed Acoustic Sensing (DAS) interrogator.  The purpose of this work is to further develop an innovative real-time subsurface monitoring method for reservoirs and tailings dams. Sisprobe is proud to be contributing its leading ambient-noise expertise to the larger HydroResearch/Silixa research project developing new optical fibre dam monitoring methods, and funded by the Swedish Energy Agency.
