Every project realized is a win challenge

Solgeo’s primary goals are to provide a high quality ground investigation and exploration service to attend needs of our clients, focused on proposing the best solution: cross-hole test, seismic network, dynamic monitoring or other. Our approach is always the same: professional.

The purpose of the microsismic network installed at the Cellino Attanasio (TE) concession is the monitoring of gas storage, managed by Edison Stoccaggio SpA

The performed activities have included the supply, installation and management of 25 stations divided into 3-4 microseismic networks in Italy.

Each station consists of a data logger Dymas 24 Vms connected to a short period seismometer, able to record signals in the international format MiniSeed and transmit them to the data center created specifically through technology SeedLink. The stations are powered by solar panels and protected in special places enclosed.

The Sw installed at the remote center processes the data in real time to the location of the epicenter and magnitude of micro-earthquakes
