Monitoring Surface Deformation with Satellite InSAR - A Tool for Time Lapse Analysis of UGS

Underground gas storage in depleted hydrocarbon reservoirs, aquifers or salt caverns can be responsible for surface deformation phenomena. Monitoring surface displacements can support safe reservoir management and provide valuable constraints for modeling the dynamic behavior of a reservoir and help achieve more effective reservoir exploitation with obvious economic benefits. Satellite InSAR represents one of the most valuable and cost-effective techniques, capable of providing high precision and high areal density displacement measurements over long periods of time.
