Abstract

Summary

This study explores the use of Interferometric Synthetic Aperture Radar (InSAR) for monitoring CO2 storage sites, offering a more effective way to measure surface deformation and understand subsurface pressure changes compared to traditional methods. It demonstrates a cost-effective workflow that allows quick access to InSAR data, automatic processing, and geomechanical modeling to support decision-making for operators.

InSAR, particularly Differential Interferometric SAR (DInSAR), is useful for tracking slow, widespread displacements caused by CO2 injection, as seen in case studies like In Salah, Algeria, and Barrow Island, Australia. The study also addresses how fluid pressure buildup during CO2 storage can cause subsurface uplift, using machine learning and analytical models to differentiate pressure and saturation changes.

In conclusion, InSAR is a valuable tool for monitoring CO2 storage, enhancing safety, accuracy, and early detection of potential issues in carbon sequestration practices.
