Discussion and Future Subsidence Monitoring
In Chap. 8, the obtained results in the Groningen subsidence area from the ERS and Envisat missions are summarized and discussed. Both the precision and reliability of PSI as a measurement technique, and the idealization precision for monitoring subsidence due to gas extraction, are addressed. Additionally, examples of the use of PSI to increase insight in reservoir behavior are shown. The advantage of the high temporal sampling is shown for the determination of the subsidence delay after start of gas production, and for monitoring uplift due to underground gas storage. To conclude, a future scenario for subsidence monitoring is sketched.
