| 1. A method of determining characteristics of an injection well, comprising:
obtaining an initial temperature profile along a deviated wellbore prior to injection;
measuring the temperature of an injection fluid prior to injection;
injecting the injection fluid into the deviated wellbore;
establishing a temperature profile; and
determining a flow profile for the injection fluid based on a well model utilizing the initial temperature profile, the temperature
of the injection fluid, and the temperature profile.
