Abstract
In seismic surface, the generated frequencies are much higher than those observed in seismic deep, so the travel time across the weathered layer can cover several cycles of train seismic waves. This layer influences the trajectories of ray in a manner that requires correct in order to obtain the proper location in depth of the reflectors of interest. We propose a method to extrapolate the times obtained from a few Up Holes to a whole section of Resistivities from a Deep Electrical Tomography.
