ABSTRACT:
In accordance with an illustrative embodiment of the invention, a technique is set forth for determining a displacement between two or more well logs separately derived from investigating devices passed through a borehole. More particularly, displacements are determined for a number of levels through use of a suitable correlation function compensated for various adverse effects. The displacements for a selected number of levels are analyzed to determine average displacements at representative levels. The average displacements and representative levels are analyzed to determine intermediate levels and corresponding distributed displacements for distributing large changes in displacements. Application of these distributed displacements at the intermediate levels minimizes changes in the nature of the logs that would be caused by abrupt application of large changes in displacements to the logs at one depth level to align the logs. The correlation function is selectively scaled and displayed as a function of successive levels for use in subsequent analysis.
