Hi, Thanks you very much for your reply, it helps me a lot. Concerning the construction of the stratigraphic model, when the grid file is interpolated from surrounding boreholes, what's happen between those grid nodes? In 2D map, we can see many pixels but in 3D model, it seems to me that the 3D model is nearly continue. Is that Rockworks makes a second interpolation between grid nodes and no with my borehole's data ?
Once again, thanks
Loann
