Operational Validation Of The Accuracy Of INSAR Measurements Over An Enhanced Oil Recovery Field

This brief note presents a preliminary confirmation of a methodology for monitoring fast, strong ground deformation in a difficult environment with the RADARSAT-2 satellite. The original aim of the monitoring was to capture the ground change present due to an aggressive enhanced oil recovery program. The ground deformation was expected to be on the order of a few centimetres per month with a spatial extent of hundreds of metres. The analysis shows that the deformation was much higher than expected. To understand the surface expression, multiple tracks of RADARSAT-2 were used to assess the error be- tween observations. This effort confirms the use of multiple tracks of RADARSAT-2 data to increase the temporal sampling of a field.
