Permeability prediction systems and methods using quadratic discriminant analysis

摘要

Permeability prediction systems and methods using quadratic discriminant analysis are presented. At least one disclosed method embodiment includes: acquiring formation property measurements at a plurality of positions along at least one borehole in a study area; identifying clusters in a plurality of points representing the formation property measurements at the plurality of postions; and determining a system permeability value for each cluster. Quadratic Discriminant Analysis (“QDA”) is used to associate one the clusters with each position along the one or more boreholes, thereby determining a system permeability prediction for each position. The total system permeability can then be predicted by aggregating the system permeability predictions.

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.
