ABSTRACT:
A technique that is usable with a well includes changing the temperature of a local environment of a distributed temperature sensor, which is deployed in a region of the well and using the sensor to acquire measurements of a temperature versus depth profile. The region contains at least two different well fluid layers, and the technique includes determining the depth of a boundary of at least one of the well fluid layers based at least in part on a response of the temperature versus depth profile to the changing of the temperature.
