A robust reservoir surveillance program is key to managing a steamflooding operation successfully. Time-lapse temperature surveys are a primary data type collected from the observation wells to evaluate reservoir heating and to monitor the steamchest. The objective of this study was to look at factors that can affect a temperature log and steps that can be taken to improve temperature-measurement accuracy. Field data and analytical assessment show that several factors can affect the accuracy of a temperature log, which can subsequently affect interpretation and operational decisions.
