Seismic & micro-seismic signature of fluids in rocks : bridging the scale gap

Through this research workshop that will take place on the 13 June 2016 at the Institute for Advanced Studies (University of Cergy-Pontoise) near Paris, we hope to contribute to a better understanding of how fluid injection/substitution or diffusion in the subsurface affects the pore/effective pressure, micro-seismic activity, rock strength, and the potential for faulting and fault reactivation. To this end, we have gathered contributions from both laboratory experimentation and field studies on reservoir rocks such as sandstones or carbonates, and tighter rocks such as granites.
The aim is two-fold : (i) discuss the commons and differences between the two scales of observation ; (ii) identify the knowledge gaps and explore the possible ways to overcome them in order to reconcile laboratory experimentation and field data interpretation. By bringing together experts from the two scales of observation, we hope to promote interactions between them and come up with guidelines on :

  • How to optimise the design of laboratory experiments to provide the most relevant data for field-scale interpretation
  • How to optimise the design of field testing/monitoring and making the best use of laboratory data
  • Identify the best-suited theoretical tools for upscaling

We would like to promote discussion among the workshop participants, based on a selected number of oral and poster presentations.

Confirmed speakers : Sergey Stanchits (Schlumberger, USA), Francois Cornet (Univ. Strasbourg), Georg Dresen (GFZ Potsdam), Doug Angus (Univ. Leeds), Marco Bohnhoff (GFZ Potsdam), Tobias Mueller (CSIRO, Australia).
