Statement

. These datasets represent a list of microseismic events recorded during and after hydraulic fracturing of two wells (named ‘PNR-1z’ and ‘PNR-2’) at the Preston New Road (UK) unconventional shale gas development site. The microseismicity at PNR-1z was monitored by Cuadrilla Resources for the Oil and Gas Authority (OGA) using a downhole array in the adjacent PNR-2 well consisting of 12 three-component geophones which was operated by Schlumberger Ltd., the geophysical processing contractor. The PNR-1z seismic catalogue also includes events recorded by broadband surface stations operated by the British Geological Survey (BGS). PNR-2 seismicity was recorded by a downhole array of 12 geophones in the adjacent PNR-1z well. The PNR-2 seismicity catalogue also includes events recorded by the combined surface network of the BGS and the operator. Along with the two microseismicity catalogues, the dataset reports the fluid injection rates at the two wells sampled at 1 second intervals. Stages for the compilation of the datasets: 1. Raw data comprising continuous recordings from downhole geophone arrays and surface seismometer networks. 2. Measurement of arrival times and amplitudes of seismic phases for individual events. 3. Calculation of locations (positions in space and time) and magnitudes for individual events. 4. Merging of results from downhole and surface arrays 5. Compilation events into a catalogue consisting of origin times, positions and magnitudes
