Early detection of brine and CO2 leakage through abandoned wells using pressure and surface-deformation monitoring data: Concept and demonstration

•We develop a method for early detection of brine and CO2 leakage.•We use pressure and surface-deformation anomalies as leakage signals.•The location and permeability of abandoned leaky wells are estimated.•Accuracy of leakage detection depends on the level of pressure data noise.•Joint inversion im...
