Abstract
The present invention relates to a system for emitting seismic waves in an underground formation traversed by a well comprising a casing (10). The system comprises a casing seal (1) allowing passage of a magnetic field, an active part generating seismic waves, made up of magnetic-field active elements (4) and arranged outside the casing seal, and a mobile magnetic field induction source (8) arranged inside the casing seal. The invention also relates to a method implementing the seismic wave emission system.
