Dick,
You could do a lookup using x as the reference field to import the Depth
values into your database. This will have to be done for each line,
unfortunately, but 20 lines shouldn't take too long. Then you could grid it
from there, as you have x and y in your database.
Where it starts to get messy is if you have several horizons to deal with.
Then it might be worth while to some sophisticated scripting.
