1. A method for predicting total system permeability of a geologic formation, comprising: acquiring formation property measurements at a plurality of positions along at least one borehole in the geologic formation; identifying clusters in a plurality of points representing the formation property measurements at the plurality of postions; determining a system permeability value for each cluster; applying Quadratic Discriminant Analysis (“QDA”) to associate each of multiple positions in one or more boreholes with a corresponding cluster based on formation property measurements, thereby obtaining a system permeability prediction for each of said multiple positions; and predicting total system permeability based at least in part on an aggregation of the system permeability predictions for each of said multiple positions.
