Spatial Monitoring of Geological Carbon Storage Progress Using Time-Lapse Satellite Images

Technical Paper

This paper proposes and validates a new monitoring approach for Geological Carbon Storage (GCS) using time-lapse satellite Interferometric Synthetic Aperture Radar (InSAR) images at a pilot project site in Kern County, California.

 

  • Understand the strong correlation between land surface uplift and pressure change, confirming InSAR can interpret subsurface events in geological carbon storage (GCS).

  • Discover the key parameters—sandstone Young's modulus and injection rate—that are most sensitive to the magnitude of land uplift detected by InSAR.

  • See how incorporating time-series InSAR images recovers more information, including the Young's modulus of both shale and sandstone, injection rate, and injection horizon.

  • Grasp the application of advanced feature extraction methods like Principal Component Analysis (PCA) and Autoencoders to handle the complexity and high dimensionality of time-series InSAR data for global sensitivity analysis.

Frequently Asked Questions

  • Carbon storage project developers, reservoir and geomechanics engineers, and teams building monitoring plans for CO₂ injection sites.

  • A method for monitoring geological carbon storage with time-lapse InSAR, tested at a pilot site in Kern County, California.

  • Uplift closely tracks subsurface pressure change, so InSAR can help you interpret what is happening at depth.

  • Sandstone stiffness (Young’s modulus) and injection rate. Time-series InSAR can also help estimate shale and sandstone stiffness, injection rate and the injection horizon.
