Project Description
On the quest to answering environmental regulation by lowering CO2 emissions in Alberta’s Oil Sands, the Black Gold CO2 storage facility was monitored. Injecting CO2 at high pressure in the geological layer can lead to multiple problems such as unintended CO2 leaking through geological faults or cracks in sealing layers or ground uplift due to an excess of CO2 pressure underground. Excess pressure could lead to fracture and leaks, thus needs to be detected.
PSInSAR was applied to the targets in red color and cycles of uplift/subsidence were detected and correlated with CO2 injection cycles. The cyclical nature of the displacement suggests that the storage area is properly filling with uplift when the pressure becomes too high and subsidence when the CO2 is settling within the storage layer; any leaks would lead to a sustained ground subsidence.
