1. A method of determining the source of a produced fluid from a multiple zone subterranean formation penetrated by a well comprising:

  • (a) introducing a first well treatment fluid in a first zone and a second well treatment fluid in a second zone of the subterranean formation, wherein the first well treatment fluid and the second well treatment fluid contain a composite comprising a well treatment agent and wherein the well treatment agent of the composite of the first well treatment fluid and the well treatment agent of the composite of the second well treatment fluid are different and distinguishable by physical or chemical analysis;

    (b) releasing the well treatment agent from the composite of the first treatment fluid and/or the composite of the second treatment fluid;

    (c) inhibiting and/or preventing the deposition of contaminants within the well and/or subterranean formation by the released well treatment agent of step (b);

    (d) transporting produced fluid from the well and/or subterranean formation, the transported produced fluid containing at least a portion of the released well treatment agent of step (b);

    (e) collecting at least a portion of the transported produced fluid;

    (f) detecting the well treatment agent of the first treatment fluid and/or second treatment fluid in the collected fluid by physical or chemical analysis; and

    (g) determining the source of the collected fluid from the detected well treatment agent.
