We developed an integrated solution to screen, assess and monitor legacy wells with non-invasive techniques, allowing us to de-risk existing storage reservoirs and unlock potential for other areas.

Our approaches combine screening and classification of legacy reports and data, with modelling of electromagnetic and acoustic signals for well integrity monitoring, both regarding casing corrosion and cement plug damages.
