For question 1, I'd suggest you take a look at the free E{Z}-kriging
utility , see http://www.ai-geostats.org/index.php?id=114
question 2 will be much simpler after you answered 1.

Dear list:
I have some doubt about sill and nugget that I want to share with you
to help to clarify it:
1) What is the effect of raising and lowering the sill and the absence
or presence of a nugget. For example, let's say I'm going to Krig
porosity. If the true variance of the porosity data is 15, what
happens to the kriged map if I make the sill value 30? what happen if
I make it 5?, What happens to the map If I have a nugget of for
example 25%?.
2) Instead of Kriging, let's say I'm doing a conditional simulation of
porosity. what are the effects raising and lowering the sill (as
above) and adding a nugget (as above)?
I'll apreciate all your support and cooperation..
with all my respect to you
