<p>A method of logging a well (2) includes the steps of moving a tagging agent into a well so that the tagging agent (14) is deposited in an earthen formation (6) of the well, which tagging agent is non-radioactive at least until just prior to entering the well; irradiating the tagging agent from a source (8) so that the tagging agent exhibits at least one tagging agent characteristic distinguishable from earthen formation characteristics, and detecting (10) the at least one tagging agent characteristic after the tagging agent has been deposited in the earthen formation.</p> |
