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