Abstract
A method of determining changing well characteristics at downhole locations based on changes in detected temperatures by permanently installed downhole sensors. The methods and tools utilized involve the establishing of baseline temperature profiles, for example, at the outset of well operations. The installed sensors may be powered are rechecked on a periodic or continuous basis for substantial deviations to the temperature profiles which are indicative of particular well condition changes such as the depositing of asphaltene or decreases in fluid velocity.
