Local and moment magnitudes of Preston New Road seismicity, 2018-2019 (NERC Grant NE/R018006/1)
This dataset is a catalogue of elastic stress models of hydraulic fracturing during the 2018 Preston New Road, PNR-1z operations (described in Clarke et al., 2019). This modelling was produced for the publication Kettlety et al. (2020), which studies the physical mechanisms controlling seismicity during hydraulic fracturing. For further details on the modelling approach and context for these data, see Kettlety et al. (2020) and the README file attached here.This is a combined microseismic catalogue of all of the seismic magnitudes recorded for microseismic events recorded during Cuadrilla's Preston New Road hydraulic fracturing operations. 5 magnitude types are given for each event: the downhole measured moment magnitude (Mw); the downhole measured local magnitude (ML); the surface measured ML; the surface measured Mw; and a combined/corrected Mw. This corrected Mw follows the procedure laid out in Kettlety et al. (2021, https://doi.org/10.1785/0220200187) and Baptie et al. (2020, Robust relationships for magnitude conversion of PNR seismicity catalogues. British Geological Survey Open Report, OR/20/042) Functionally, it combines the surface measured Mw and the downhole measured Mw corrected using Equations 4.6 and 4.7 of Baptie et al. (2020). Also included are event origin times, associated injection stages (as described in Clarke et al., 2020, https://doi.org/10.1785/0220190110, and Kettlety et al., 2021), whether this stage was a "minifrac" (just for PNR-1z), the "relative fracture order" (RFO) of that stage, and it's downhole measured location (easting and northing in BNG coordinates, and depth BSL). Downhole measurements Mw and ML were conducting by Schlumberger Ltd. on behalf to the Preston New Road operator Cuadrilla Resources Ldt., and surface ML and Mw were measured by the BGS in Baptie et al., (2020).

This data was produced within the Unconventional Hydrocarbons in the UK Energy System NERC project (within SHAPE-UK). This reanalysis of the earthquake magnitudes was conducted after downhole measurements were found to not be accurate for the largest events, and surface measurements had to be used. Corrections to all downhole measurements were conducted after the surface data was added in once discontinuities were noticed in the magnitude-frequency distribution. This process produced a single, corrected moment magnitude for the events in these catalogues, which are presented here. This process is detailed throughly in Kettlety et al. (2021) and Baptie et al. (2020). It was deemed valuable that all measures of magnitude for this data should be published in a single format, to help future study.
