1. An apparatus comprising:
a completion string installed in a well, the completion string including a plurality of inflow control valves for controlling flow of formation fluid into the completion string;
a plurality of thermal detectors positioned along the completion string downhole in the well; and
an analysis system operable to:
determine, via the plurality of thermal detectors, thermal characteristics of a downhole fluid flowing through the completion string at the positions of the plurality of thermal detectors;
determine phase fractions of the downhole fluid using the determined thermal characteristics; and
control the inflow control valves based on the determined thermal characteristics of the downhole fluid at the positions of the plurality of thermal detectors.
