Summary:
Whenever fluids are injected or extracted from a reservoir, pore pressure and stress field change both in the reservoir and in the overburden. According to geomechanics, such variation in stress or pore pressure can produce a reservoir compaction, trigger pre-existing faults or even generate new ones. Al these events will translate into surface deformation, which turns to be a valuable information to better understand the subsurface phenomena. In the last few years, the analysis of multi-temporal SAR data sets represents an important layer of information, for reservoir monitoring and management, thanks to the possibility to provide surface deformation data with millimetre precision over large areas. In order to help decision makers in analyzing different scenarios and planning specific actions it is important to update ground displacement measurements every new satellite acquisition.
