Computing stratigraphic residuals for boreholes: solid model or grid

[jacksonn]

Hello,

 

I have ~290 boreholes with stratigraphic picks; 5 units. Some boreholes only have 1 unit; some have all 5 units. I've variously created solid strat models and top/bottom unit grids for selected units.

 

What is the best way to compute residuals for the top/bottom stratigraphic elevations, from the boreholes relative to the computed model/grids? Ideally, I would have them in both tabular form (to review statistical distribution) and mapped to see spatial distribution.

 

I can do this in Arc/Python, but I would prefer to reduce the switching between software when possible. 

 

Thanks!

Further, is there a simple way to (iteratively...) "jackknife" the residuals by omitted a subset of boreholes and comparing the computed grid to the omitted elevations?
