A surface geophone is planted and connected to the VSP acquisition logging unit. Data from this geophone are recorded, simultaneously with the downhole seismic sensors, for every source point in a walk away, 3D VSP or surface 3D survey. Statics are computed for all source points using refraction analysis. A weathering map is produced from the calculated statics.
