Re: Adding additional data
You could try and load the values as "Point Well Data". This is basically a tab delimited ASCII file with a depth (MD) collumn and a number of collumns with values.
If you need to load text you could do this too via this router or you could load a comment log. Look at the format preview when selecting the file type in petrel to understand the syntax of the file you need to create.
You can display both data objects in a well section window
