Abstract
Method of producing impact point position probability maps for a well. It consists in defining a fixed, invariant target point chosen a priori on an initial location E0 of the surface S, discretizing the surface S with the aid of a grid composed of nodes and of grid cells, assigning at least one elementary geometrical uncertainty vector to each node of the grid of the surface S, determining a statistically significant number of occurrences of locations of the surface S as a function of the geometrical uncertainties affecting it, projecting the target point onto each occurrence of location of the surface so as to deduce a point of impact therefrom, transferring the set of impact points onto the location E0 of the surface S by allocating, to each of these points, surface co-ordinates identical to those which it had on the occurrence of location of the surface containing it.
