Surface Deformation Monitoring with InSAR

From 2004 to 2013 BP, Sonatrach and Statoil used CO2 storage techniques in Krechba (Algeria) for the In Salah project, moving carbon dioxide from the close-by gas field and storing it underground to permanently remove it from the atmosphere. Starting in 2011 TRE (Tele Rilevamento Europa) used historically acquired SAR imagery and on-going InSar surface deformation monitoring to understand the movement of CO2 in the subsurface. The analysis of newly acquired and stored EO data let construct maps of ground deformation, which highlight uplift related with the gas injection. For more information click here.
