Abstract
The quality of steam downhole is determined by injecting into the steam first and second tracers, each tracer having an affinity to a single of the two phases, and then sensing the passage of the tracers over a pair of sensors spaced apart or known measured distance. Thus the velocity of the phases, the slip ratio between the phases and the steam quality can be determined.
