Abstract

In France, onshore seismic surveys often include uphole shots in small wells at least to the bottom of the weathered zone, typically 50 m to 180 m deep, and with a surface spacing of about 2 km on the seismic lines. Up to present, these uphole shots are used only to produce a time-depth curve in order to define the velocity model of the near surface layers and calibrate the long wave static corrections. In the 60's, wavefront diagrams were commonly produced from multioffset uphole time picks (Meissner, 1961, GP, Vol 4, p 533).
