Litho implicit modelling

Hi Clinton

On the image bellow is  composed the question

Normally you would create an implicit model of your youngest feature first, and then work your way back in geological history. When you are working your way back you would choose to ignore the younger lithology when creating your implicit model and then Boolean the youngest lithology against the older.


i think this is same answer send to me long ago by email

as i put in second post it is not prblem to solve when two formations superpose each other by Boolean operation

main issue is how to fill the gaps 

 where second litho type is not generated as in the schema above

thanks reso

Hi Reso, 

If you want to manually tweak your results, you can use Attribute Modelling:

  1. Run your process in Lithology and output the interpolated points.
  2. Once it is done, open your interpolated points in Vizex and add some 'fake points' where you want your wireframe to expand.
  3. Give them a positive or negative value if you want to include or exclude the new region.
  4. Run Attribute modelling with a cutoff value of 0 and it should look a bit more what you want it to be.
  5. If it is too big, just do a boolean operation on the 2 wireframes.

thanks for the reply

the way that you suggest,   when there are a lot of rock types and adding here the faults as well,   in my opinion is becoming an 'implicit method' which as matter of fact it is what i wand to avoid

Any how thanks again
