As discussed in this paper, random errors can be eliminated by a suitable logging procedure whereas systematic errors have to be com- pensated for by carefully normalizing log data with respect to a fixed geological model...

... ABSTRACT To obtain quantitative formation evaluation from well log data, original information must be corrected by a process of normalization. The procedures and systems used to normalize data are described. Examples of the techniques are presented and application in various areas is shown...
