Abstract
The Havnsø structure in the Kalundborg CO2 storage site is a four-way anticline closure that has been evaluated as a suitable CO2 storage unit. As an input to baseline monitoring of surface deformation, we used the C-band satellite data from European Space Agency (ESA) for Interferometric Synthetic Aperture Radar (InSAR) analysis to detect surface deformation with millimeter-resolution. The data were processed using GMTSAR software. Although challenges with high levels of vegetation and small water lakes reduced the coherency of backscattered signals, but enough reliable result obtained to make our analysis possible. We Integrate InSAR results, with geomechanical model and feasibility studies for deployment of a local seismic network to tailor the planned baseline monitoring strategy in the Kalundborg CO2 storage site.
