With regard to multi-well digital well log analysis projects: proceed at your peril if you do not plan to normalize your data set.
From experience in dealing with digital well log data from multiple wells, almost all interpretation busts or failures, aside from using the wrong interpretation procedures, can be linked back to poorly calibrated data and not doing a proper and consistent normalization prior to analysis.
