BRGM has invested for long in the development of methods for geological modelling. These methods have progressively moved to industrialization through « homemade » software (GDM-Multilayer, 3DGeomodeller). Considering the wide range of applications and geological settings, the choice for own developments allows better flexibility and adaptive capabilities on tools and methods. Modelling geology in complex tectonic environment: In the frame of Potential and Gradients Cokriging method (Lajaunie et al., 1997), one of critical parameters when interpolating natural objects concerns the anisotropy which in current methods is at best considered as uniform within the domain. The introduction of spatially variable anisotropies will allow to model structures such as folds whose characteristics are variable in space, intrusive systems in orogenic domains, or even meandering alluvial systems. This will contribute to increase the realism of geological models.
