Prospection of ground water II

Hybrid seismic mapping of faults and tectonic features for positioning a water exploration well near Miécourt, Switzerland (2006)

 

Situation map of the five seismic lines and of the location of the exploration well. The major faults portrayed have been derived from the results of the seismic survey.

Upper picture, hybrid seismic section recorded and interpreted by GeoExpert. Numerous reflection events, occasionally rather discontinous, are portrayed. Decompaction zones and faults are in evidence (hatched in blue colour). Lower picture, the geological cross section across the Gourgenay - Charmoille basin updated by the seismic results and by the inclined exploration well.

Excerpts from the Swiss Bulletin for Applied Geology:

  • «The hybrid seismic survey for imaging the subsurface structures down to a depth of approx. 600 m was carried out by GeoExpert AG between 12. and 21. September 2006. The positioning of the drilling location was based entirely on the interpretation results of the five seismic sections recorded.»
  • «The ground water prospection project was successfully concluded with the drilling of a deviated well near Miécourt in 2008. Artesian pressured water was found at a depth of 390 m at the base of the Malm limestone formation.»
