Abstract
The invention concerns a method for extracting a geological horizon and related properties of a seismic representation, comprising a step () which consists in digital modeling with continuous local seismic traces, calculating the optimal offset and defining a conditional neighbourhood of a reference central continuous local seismic trace; a step () which consists in defining a two-dimensional matrix whereof the line and column indices correspond to the coordinates of the geophones; a third step () which consists in selecting a seed point; a fourth step () which consists in determining the point vertically closest to the seed point and a fifth step () which consists in assigning to the point P(p,q,t) the value P(p,q,t+hij,pq,k), where hij,pq,k is optimal offset of the neighbouring point P(i,j,k), so as to estimate the related properties of the conditional neighbourhood thereby filling the two-dimensional extraction matrix of step ().
