Workshop 2

Multi-scale in situ investigation of fractured media: theory and field practice

Ploemeur, France, 15th to 20th October 2017

The workshop aimed to provide advanced knowledge and practice on state of the art field methods for quantifying heterogeneous subsurface storage compartments at different scales in fractured media and detecting limited-size active fractures, orientation, extent and connectivity by single and cross borehole tests. The workshop took advantage of the existing hydrogeophysical experimental infrastructures present at the H+ Ploemeur observatory to show the complementarity of different methods to investigate complex fractured media through field practice.

Several presentations were held:

  • About the Ploemeur Site, by O.Bour
  • About the Characterization of Subsurface flow,  by O.Bour
  • On the field (Relations depth-surface in Guidel + deformation), by Laurent Longuevergne
  • DFN model, by C.Darcel & P.Davy
  • Gravimetry, by P. Vermeulen
