Abstract

A robust reservoir surveillance program is vital 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. Factors that will affect temperature measurement include logging speed, sensor response time, and steamchest temperature. Evaluation of these factors revealed that the higher the logging speed, the greater the error in measured temperature. Also, the higher the steamchest temperature, the greater the error in measured temperature, and the longer the sensor-response time, the greater the error in measured temperature. Several field examples are presented to illustrate errors introduced in temperature measurements caused by running at higher or nonuniform logging speeds, and the effect of steamchest temperature on measurement error.
