New successful technical and logistical challenge for SEMM logging with the rapid mobilization of a complete workshop on the Réunion island. On site, the soil presents strong lateral and vertical heterogeneities. It is therefore critical to carry out micro-seismic measurements in order to better understand the geomechanical parameters to adjust the excavation program. Micro-seismic data, coupled with a caliper log to control the quality of the contact tool/borehole, allow to obtain the propagation speed of P waves in the formations.
