Abstract
It has been found that in many instances it is desirable to be able to determine where fluid in a well originates. To that end a tracer assembly is provided where the tracer assembly becomes a portion of the tubular that is run into the wellbore. Preferably the tracer assembly provides an exterior barrier whether permanent or temporary to fluid flow outside of the tubular and also provides an interior barrier to fluid flow as it passes through the inner bore of the tubular. The interior barrier is adjustable so that upon command it provides access from the interior of the tubular to at least a portion of a cavity within the tracer assembly. The cavity is provided with a tracer or tracers so that as fluid is allowed within the interior cavity portion of the tracer is eroded, dissolved, or otherwise mixed with the fluid and the tracer that is now mixed with the fluid is transported to the surface.
