Workshop 4

This workshop introduces the power of Satellite Interferometry (InSAR) as a transformative tool for the Global Energy Transition.
Participants will learn how millimetric surface displacement data serves as a cost-effective early warning system for subsurface hazards in CCS, hydrogen storage, and geothermal projects.
Moving from basic principles and advanced algorithms (SqueeSAR®) to practical case studies, the session explores how to mitigate risks such as caprock failure and well integrity loss.
Furthermore, it highlights how InSAR provides essential insights into civil infrastructure integrity and regulatory compliance, effectively eliminating the HSE risks associated with traditional on-site instrumentation.

Course Outline

The workshop is designed to take participants from theoretical foundations to practical, hands-
