description: Shale oil and gas exploitation by hydraulic fracturing experienced a strong development worldwide over  the last years, accompanied by a substantial increase of related induced seismicity, either consequence  of fracturing or wastewater injection. In Europe, unconventional hydrocarbon resources remain  underdeveloped and their exploitation controversial. In UK, fracturing operations were stopped after  the Mw 2.3 Blackpool induced earthquake; in Poland, operations were halted in 2017 due to adverse oil  market conditions. One of the last operated well at Wysin, Poland, was monitored independently in the  framework of the EU project SHEER, through a multidisciplinary system including seismic, water and air  quality monitoring. The hybrid seismic network combines surface mini-arrays, broadband and shallow  borehole sensors. This paper summarizes the outcomes of the seismological analysis of these data.  Shallow artifcial seismic noise sources were detected and located at the wellhead active during the  fracturing stages. Local microseismicity was also detected, located and characterised, culminating in  two events of Mw 1.0 and 0.5, occurring days after the stimulation in the vicinity of the operational well,  but at very shallow depths. A sharp methane peak was detected ~19hours after the Mw 0.5 event. No  correlation was observed between injected volumes, seismicity and groundwater parameters.
