Abstract:
Continuous measurement indicia between casing collars of a pipe segment of a well bore casing is obtained from signals obtained by sensing innate, persistent and unaltered characteristics, e.g. magnetic permeability, of the pipe segment along its length, and using the signals to perform a downhole function, e.g. a gravity measurement, at an indicated location.
