A shroud assembly that is conveyable within a wellbore extending into a subterranean formation via a tubular member. The shroud assembly and at least a portion of the tubular member at least partially define an annular volume around the tubular member. The shroud assembly includes apertures permitting fluid flow between the wellbore and the annular volume. A fluid tracer positioned within the annular volume is carried by flow of the fluid from the annular volume into the wellbore or tubular member.

Fluid tracer installation

An assembly that is usable with a well includes a base pipe, a shroud that is disposed radially outside of the base pipe and tubes. The tubes are disposed radially outside of the base pipe and are radially inside the shroud. The tubes longitudinally extend along the base pipe and radially expand to radially expand the shroud in response to pressurization of the tubes.
