Disclosed is a well logging process of finding depth zones within each of which a number of logs are mutually consistent within a respective selected tolerance. Logs which have good vertical resolution, for example the porosity logs, are used to zone a depth interval, and thereafter logs which have poorer vertical resolution, such as basic resistivity logs, are divided into the same zones. The zones can be used, as non-limiting examples, to rectangularize the logs and thus reduce probable noise components thereof; to crossplot by zone rather than by depth level, and thus again reduce probable noise in crossplots; to speed up procedures which utilize large vertical segments of logs by using therein zones of constant measurement level rather than measurements for each individual depth levels; and for studies of sedimentary depositions and inter well fitting and recalibration.
