Surface deformation monitoring can provide valuable information about the dynamic behaviour of reservoirs under production. Measuring these deformations can help to identify undepleted compartments, detect fault reactivation, mitigate risks associated with well failure, constrain geomechanical models, and aid field management decisions. We have demonstrated that satellite InSAR is a powerful tool to measure surface movement and is useful for managing reservoirs under production. SqueeSAR™ is the latest InSAR algorithm developed by TRE. The InSAR analysis covers a stacked carbonate reservoir in the Middle East. The top reservoir is a mature gas with a depth of approximately 750 m, which is known to compact. The lowest reservoir is an oil reservoir with a 1200 m depth produced by a water-flood. Both reservoirs are intersected by a major graben fault, trending NE-SW, as well as numerous additional extensional faults. Approximately 500 producer and injector wells have been drilled in the area. A comparison with existing GPS measurements has shown a good agreement between InSAR and GPS data. We have also inverted InSAR data using a geomechanical model to obtain reservoir strains. These compare well with pressure change maps from reservoir simulations. There is also an intriguing correlation between known fault systems at the reservoir level and the surface displacement data by satellite InSAR.
