Abstract
A method for three-dimensional modelling of a geological volume, which consists in defining cells adapted to the critical surfaces of the geological volume to be modelled; defining an assembly of polyhedral macrocells (M) adapted to the geometry (1) of the geological layers of the volume to be modelled; parametering the geological space to match the observed geological domain and a parametric domain by associating with a point belonging to the geological domain an image point located in the parametric domain; then defining a virtural subdivision of the polyhedral macrocells (M) into hexahedral microcells (m) whereof the geometry is obtained by subdividing the geometry of each macrocell (M).
