Abstract

During several years passive seismic monitoring was performed at Céré-la-Ronde, an underground gas storage facility located in a saline aquifer. The permanent survey delivers interesting information on the initial reservoir fill-up, especially when considering the geomechanical behavior of the site. Location of microseisms by using two techniques is discussed. A comparison between the 1D and 3D results points out the limit of using simple structural models and gives some idea on associated uncertainties. The discussion deals also with the necessity of improving the workflow to take into account the induced seismic hazard in coupled reservoir and geomechanical modeling and constraining models with passive seismic data too. This experience is very useful in the context of CO2 storage and it constitutes an excellent analogue for short term considerations.
