So it&#8217;s not continuous on a 2D profile. In this case I will obtain 2 facies: one facies is the initial facies defined in the layer (i.e. Coal pure) and one digitilized facies representing sand. This model can be improved in adding a third facies (or more) for shales representing the flood plain in a fluvial system.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/aurelieng.fr\/wp-content\/uploads\/2026\/05\/image-7-1024x688.png\" alt=\"\" class=\"wp-image-813\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Here is an example with only 2 facies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In Petromod it&#8217;s possible to manually assign different facies for one single layer.
