Abstract
A system and a method manage temperature in a wellbore. A thermal barrier may be positioned within the drill pipe and/or the drill collars to obtain a desired downhole temperature and/or control the effect of thermal energy in high-angle and horizontal wellbores. Downhole measurements, such as real-time measurements and/or recorded measurements, may be used to update models, such as steady state models and/or dynamic models. The downhole measurements may validate the static temperature gradient and may provide information about the thermal characteristics of the one or more formations in which the wellbore is located.
