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. date: 2018 date_type: published publication: Scientific Reports volume: 8 number: 1 publisher: Nature Publishing Group id_number: doi:10.1038/s41598-018-26970-9 issn: 2045-2322 official_url: http://doi.org/10.1038/s41598-018-26970-9 access_IS-EPOS: limited owner: Publisher acknowledgments2: IS-EPOS_platform acknowledgments2: SHEER_project citation: Lopez-Comino, Jose Angel and Cesca, Simone and Jarosławski, Janusz and Montcoudiol, Nelly and Heimann, Sebastian and Dahm, Torsten and Lasocki, Stanislaw and Gunning, Andrew and Capuano, Paolo and Ellsworth, William L.
