ABSTRACT:
An improved formation density logging tool is provided that is effective in cased holes. The improved tool utilizes three detectors: a first detector for primarily compensating for the casing; a second detector for primarily compensating for the cement; and a third detector for providing formation information. The tool provides an improvement over currently-available two-detector density tools which are normally useful only in open holes. It is anticipated that the tool provided herein will be useful in both open and cased holes.
