摘要
Distinctive and analytically distinguishable water-soluble and oil-soluble tracer compositions are applied as coatings to the exterior surface of one or more lengths of production tubing installed in a horizontal well bore between open-hole packers adjacent one or more inflow control devices, (ICD), whereby water and/or oil contacting one or more of the respective tracer coatings and passing a faulty open-hole packer seal will solubilize the tracer coating(s) and be detectable by appropriate tests on the produced water and/or hydrocarbon fluids at the earth's surface.
