Abstract
A method is disclosed for determining, without carrying out a well-velocity survey or making a priori assumption on the velocity of the first medium, the primary static corrections to be applied to sets of seismic traces after seismic prospecting operations in an underground zone. A velocity model allows calculation of the corrections is essentially obtained by performing, for each position of the common midpoint, a continuous and progressive inversion of the first arrival times (time-distance curves), from short offsets to longer offsets, so as to allow going from a sequence of pairs connecting the offsets to the arrival times picked to a sequence of vertical data connecting the depth to the velocity or propagation of the waves.
