| 1. A method of localizing the source of a particulate produced with a fluid through a wellbore, the method comprising the
steps of:
(A) providing marking composition comprising at least one marker that:
(i) is capable of binding with a particulate; and
(ii) has a detectable property distinguishable from the particulate;
(B) introducing the marking composition:
(i) through a wellbore; and
(ii) into contact with at least a portion of a subterranean formation penetrated by the wellbore;
(C) obtaining fluid produced through the wellbore; and
(D) analyzing a particulate produced with the produced fluid for the presence of the marker.
