Abstract
Improved methods and apparatus are provided for correlatively matching, recording, and displaying, two or more sets of logging data measurements with respect to the borehold depth at which they were generated, and independent of their historical or real-time character. In a particular embodiment of the invention, measurements from each set of data derived or sampled at correlative depths are adjacently displayed in graphical form during a logging operation. The depth offset between the measurements is visually or automatically detected, and in response thereto, the subsequent correlation of other selected measurements and depths at which subsequent measurements are derived are thereby adjusted for further processing, display and recording.
