Microseismic downhole network - Soultz-sous-Forêts 1995 Stimulation and Hydraulic Tests

The microseismic network in operation during the 1995 stimulation, injection and circulation experiments represents a slightly modified version of the 1993 system. It consisted of accelerometers (4-component sensors) built by the CSMA in boreholes 4550, 4601, 4616 and of a single hydrophone in EPS1. These sensors were used throughout the 1995 experimental programme. A further hydrophone was deployed in GPK1 at a depth of 3480m to monitor the brine injection (Wilson, S.A., Jupe, A.J., Jones R.H. and Dyer, B., 1996.Microseismic results from the 1995 Soultz experimental programme, CSMA Report for Socomine, January 1996.).


The X,Y,Z coordinates in the file refer to the local coordinate system with the GPK1 wellhead as origin:

X: Easting in meters from GPK1 wellhead (toward magnetic East)

Y: Northing in meters from GPK1 wellhead (toward magnetic North)

Z: Depth in meters from GPK1 wellhead

The local coordinate system is based on the UTM32 system.


The coordinates of the stations in the local coordinate system have been obtained from the thesis of S. Bourouis (Sismicité induite et comportement mécanique d'un massif granitique fracturé par injection d'eau).


The exact coordinates of the GPK1 hydrophone have not been retrieved and so are not in the file.


The latitude, longitude and elevation in the WGS84 coordinate system have been derived from the local coordinate system.
