ABSTRACT:
A method of establishing a stratigraphic model of the subsurface from an acoustic impedance profile A.sub.o ={a.sub.o (n),n=1,N} corresponding to a series of reflection coefficients R.sub.o ={r.sub.o (n),n=1,N}, where n is an index relating to the depth sampled in time t, and from a seismic section comprising a plurality of seismic traces T.sub.i (t),i=0,I recorded in response to the emission of a seismic wave of signature W(t), the method comprising the following steps:
