SRD Seismic Reference Datum. Two different SRD have been applied for the Jura domain and the Geneva Basin because of the elevation difference and the absence or poorly amount of Cenozoic sediments in the Jura Mountains. The conversion velocities derive from the adjustement between well data and seismic lines
