Miniaturized Annular Sensor Aids in Well Integrity, Production Monitoring

This paper presents an intelligent tube solution that combines data retrieved by the sensors with the actual resistance of each pipe in the well to allow adjustment of production parameters while ensuring installation safety.

The integration of a pressure and temperature sensor element in tubulars is possible as the result of microelectromechanical systems (MEMS) technology. Low-power consumption combined with an adapted transmission technology allows use of this technology inside an oil and gas well. Operators can use embedded sensors to access previously inaccessible well areas in real time. The qualification of this technology is completed to ensure the integrity of the system and its long‑term viability.
