Microseismic catalogue of the downhole network by B. Dyer - Soultz-sous-Forêts 2000 Stimulation

Description

Microseismic catalogue of the 2000 episode at Soultz-sous-Forêts calculated by B. Dyer (Semore Seismic) using the downhole network. Number of events: 13986.
Microseismic monitoring of the hydraulic program at Soultz took place between June 30th and July 18th. During the program, a total of 31511 potential seismic events were recorded from which 13986 seismic events were located.The catalogue covers the two hydraulic tests realized during the 2000 episode. Only the events with an RMS misfit <10 ms were accepted. Time corresponding to the corrected waveforms distributed on the CDGP has been added.
Time period: 30/06/2000 19:09:38 - 19/07/2000 07:54:17 (UTC time).

The data parameters are the following:
Column 1: Event number
Column 2: Date (local)
Column 3: Time (local)
Column 4: Date (UTC) *
Column 5: Time (UTC) *
Column 6: Date corresponding to the corrected waveforms distributed by the CDGP (UTC) **
Column 7: Time corresponding to the corrected waveforms distributed by the CDGP (UTC) **
Column 8: Easting from GPK1 wellhead ***
Column 9: Northing from GPK1 wellhead ***
Column 10: Depth from GPK1 wellhead ***
Column 11: Latitude WGS84 ****
Column 12: Longitude WGS84 ****
Column 13: Elevation WGS84 ****

* The UTC time has been calculated from the local time.
** Some date and time corresponding to the corrected waveforms are missing. Discrepancies in the time were found with the waveforms for 87 events. Thus, the time corresponding to the corrected waveforms is given for 13899 events only.
*** The local coordinate system is based on the UTM32 system.
**** Latitude, longitude and elevation have been derived from easting, northing and depth from GPK1 wellhead.
