Identification of deformation pattern changes caused by enhanced oil recovery (EOR) using InSAR

Technical Paper

This paper presents a method for identifying changes in ground deformation patterns, specifically those caused by Enhanced Oil Recovery (EOR), using Interferometric Synthetic Aperture Radar (InSAR).

 

  • Learn how Interferometric Synthetic Aperture Radar (InSAR) can be used to monitor ground deformation caused by enhanced oil recovery (EOR) activities with millimetre-level precision.

  • Understand the cluster-wise multiple hypothesis testing method for automatically identifying spatial and temporal irregularities in InSAR deformation patterns.

  • Discover the constrained least squares estimation (CLSE) method, which incorporates spatio-temporal correlation and contextual knowledge to improve parameter estimation.

  • See a practical demonstration of the method using TerraSAR-X images over an EOR site where ground movements, including sudden uplift and subsidence, were identified.

  • Grasp the importance of identifying deformation pattern changes to prevent damage to wells, maintain production efficiency, and ensure safety during hydrocarbon activities.
