ABSTRACT:
The invention concerns a method for smoothing a subsurface property in a geological structure represented by seismic measurements comprising a step (100) which consists in digital modelling by continuous local seismic traces, calculating an optimal offset and defining a conditional neighbourhood of a reference central continuous local seismic trace; a step (101) which consists in selecting the property to be smoothed on a conditional neighbourhood; a third step (102) which consists in substituting properties of the conditional neighbourhood with offset properties; and a fourth step (103) which consists in selecting an average of the properties offset on the conditional neighbourhood at step (102).
