ABSTRACT:
A method wherein a plurality of solid particle packs, often called gravel packs, are emplaced in a wellbore to prevent production of solids from formations into the wellbore, the improvement comprising incorporating in each pack a tracer material which is unique to that particular pack. Thereafter, fluid produced from the well can be analyzed at the earth's surface to determine if any and, if so, which pack is leaking solid particles into the well. Subsequent workover of the well can then be limited to the pack or packs indicated to be leaking rather than being directed to all packs in the well.
