determining whether the formation has been fully stimulated based on the analysis.

14. The method of claim 13 wherein the channeling step comprises:

channeling at least a portion of the drilling fluid return through a system of mixing and separation units;

dissolving and removing oil and clay;

retaining the proppant in a clean stream; and

moving the cleaned stream into a detection unit.

15. The method of claim 14 wherein the analyzing step further comprises using a particle detector to identify presence of radioactive proppant in the channel stream.

16. The method of claim 15 wherein the particle detector comprises one of an alpha, beta and gamma particle detector.
