Detection of surface deformation related with CO2 injection by DInSAR at In Salah, Algeria

AbstractSurface deformation around CO2 injection wells at In Salah, Algeria was analyzed by satellite-borne SAR data. The surface heave rate up to 7 mm/year was detected around all of the three injection wells. The analysis of the deformation series has revealed that each injection well has different deformation history. The surface heave pattern shows a NW-SE trending elongation which is the direction of the anticline axis, suggesting certain relationship between the structural feature and the distribution of injected CO2. This technique will hopefully provide us with a powerful and a cost-effective tool for monitoring of behaviors of the injected CO2
