Hi all,
This is more a help on ideas that on actuall R code. Those of you which are
geologist or work with boreholes woudl understand that i would like to achieve.
I'll tr to explain as good as I can...so here it goes..
I have around 1000 geomechanical (geological) borehole logs in a database. The
logs contain staial info, lithology and some laboratory data. My initial goal is
compare the boreholes that are closer together (ie.e closer that 50 meters) to
see if they are similiar lithologicaly. I thought maybe this can be done with
some kind of multiple
regression analysis where one would test if layers (ie. Clayey layer in Bhole 1
in depth 5m and in Bhole2 this layer is in depth 7 meters) are in same depth and
if geology on
that depth is the same in Bhole1 as in Bhole 2. For example if boreholes would
have similiar lithology on similar depth that the regresion R^2 would be 1 and
if not that it would be less than 1.
This is of course my idealized way of approaching the problem. The idea is to
get a general a feel for the heterogenity of the changing geology (in depth
profile) over and area and to create a map
of heterogenity of geology of the observed area. Does any of this make sense are
i am way off?
Any ideas and/or experiences with such a problem is greatly appreciated,
Regards, m
