Characterization of seismic noise amplitude recorded by a vertical array installed in a deep borehole at the S. Potito-Cotignola gas storage field (Northern Italy)
Camilla Rossi1,2,3, Francesco Grigoli4, Paolo Gasperini2, Stefano Gandolfi3, Timur Gukov5, Chiara Cocorullo1,6, Paolo Macini3
Here we analyse continuous seismic noise from January 2019 to December 2021 recorded at underground gas storage site of S. Potito-Cotignola in the Po Valley (Italy). We use a broadband (BB) seismic station at surface and a vertical array composed by 6-short period 3-components seismometers installed at depth ranging between 35 to 285 m in borehole at the same location of the BB sensor, installed at industrial site.

We found that:
  • the maximum difference between the deepest instrument and the one at the surface is about -33 dB at 5Hz, while for the most extreme frequencies of the investigated range the noise reduction ranging from -10 to -15;
  • the dependence of noise levels (in dB) with depth follows a logarithmic empirical law;
  • the lower magnitude event shows the maximum difference of SNR between the deepest sensor and the one at surface of about 20 dB, in agreement with the noise amplitude level reduction range.

Microseismicity monitoring with SeisComP and 3D local velocity model
Camilla Rossi1, Chiara Cocorullo1, Timur Gukov2, Francesco Grigoli3
In this work we show how SeisComP can be optimized for real-time data-processing for microseismic monitoring of an Underground Gas Storage field in Northern Italy.

We analysed to 2-years of continuous seismic data recorded by a network composed of 15 (surface and borehole) stations.

Our processing routine for this seismic network is the first application in Italy where a 3D velocity model is fully integrated within the real-time microseismic monitoring operations, as suggested by the Italian Guideline for Microseismicity Monitoring on Industrial activities.

It was constructive, interesting and fun! We participated in several events, including Startup Safari, international meetings and Pitch Session.

We met corporate and got to know several potential customers or partners, to whom we showed the innovative methodologies that SEISMIX offers.
