The present disclosure provides a method of normalizing characterization information comprising: defining a plurality of characteristics, for each characteristic defining a set of allowed values and defining a logging interval. The method further comprises: at a plurality of logging intervals, selecting a value from the set of allowed values for a characteristic of the plurality of characteristics, and storing the selected value for the characteristics at the plurality of logging intervals. The present disclosure also provides a system for correlating log information comprising: a core set log data module for storing core set log data information, an electrical log data module for storing electrical log data information, a correlation module for correlating the core set log data information with the electrical log data information, and an input/output module for inputting and displaying the core set log data information the electrical log data information.
