Automatic microseismic monitoring is real-time 24/7.
Manual review of automatically located seismic events is performed every day.
Instead, an off-line analysis is carried out with ad hoc developed software in cases where it is necessary to reprocess the data, or treat it with different methodologies from those used in real time.
At the customer's request, seismic event location performance can be further improved by optimizing P- and S-wave velocity models.

Seismic monitoring usually lasts for several years. It is therefore useful, after a certain period, to statistically analyze the evolution in the space-time-magnitude domain of the seismicity detected in the area of interest and possibly correlate its variation with industrial activities.

Distributed Fiber Optic Sensing (DFOS, including Distributed Acoustinc Sensing, DAS), is a new seismic data acquisition technology, tht is becoming increasingly popular in seismic monitoring operations at different scales. DFOS is particularly useful for microseismic monitoring in the geoenergy sector, including conventional and unconventional oil and gas production, Underground Gas Storage (UGS), Carbon Capture and Storage (CCS) operations, and geothermal energy exploitation.
We develop:

• reliable and robust detection methods for an efficient microseismic DAS monitoring;
• denoising workflow for DAS signal enhancement to enhance events detectability;
• full-waveform based methods for microseismicity characterization with DAS data.

Upon request, SEISMIX organizes a course on induced seismicity monitoring. Ideally aimed at technicians and professionals working in industries related to the exploitation of subsurface georesources, it covers the following topics:

• General introduction to the problem of induced seismicity
  
• Physical mechanisms governing the phenomenon of induced seismicity
  
• Seismic networks and instrumentation
  
• Analysis of microseismic data
  
• Interpretation of microseismicity data and modeling
• Discrimination between induced and natural seismicity
  
• Tools for risk mitigation
  
• Induced seismicity and communication
  

The course is modulated according to the client's needs. It can be aimed at providing an overview of various topics concerning induced seismicity, or it can focus on specific topics, such as data processing.
