Surface displacements on the order of millimeters to centimeters have been reported at many oil fields and CCS fields, while some sites have no surface displacements despite huge volumes of hydrocarbon production, injected CO2 and/or water such as million tonnes per year. The distribution patterns of the surface displacement are investigated for selected fields by DInSAR (Differential Interferometric Synthetic Aperture Radar) analysis using Satellite SAR data. Reservoir properties that may determine whether the surface is deformed by hydrocarbon production or CO2 injection are compared for selected sites.
