Validation of sensing skin and well integrity monitoring techniques on field sites

TWI to validate the SHM system (developed in D 6.3) under operational conditions at the CO2 storage injector/producer at the Rusanda site and geothermal well at St Gallen. This report will describe the results of on-site integrity monitoring tests. For the electrically based sensing skin technique, these are the first on-site tests, and the main focus will be on testing the tolerance of the sensing skin to changing environmental
