Abstract :
We describe a novel interrogation scheme that enables multipoint measurement of temperature and pressure in harsh environment CO2 sequestration wells. Measured MEMS sensor responses are compared with finite element modeling to suggest accuracies better than ±0.1% for downhole pressure measurements.
