With the magnetometric resistivity method (MMR), electrical property contrasts in the ground are obtained from the measure of the magnetic field induced by a galvanic source. Due to the fact that the measurements are done with a magnetic sensor, MMR offers many advantages for monitoring: easier deployment in boreholes (no contact needed) and problems related to electrode installation and corrosion are avoided, also the problem of noise in conductive media is reduced because the magnetic field is a function of current density and not conductivity. The Field Research Station (FRS) is an experimental site operated by the Containment and Monitoring Institute of Carbon Management Canada where are controlled CO2 release experiment is planned for the next 5 years. A preliminary numerical study showed that MMR is suitable for monitoring a CO2 plume at the FRS. In this contribution, we present the results of a baseline survey conducted at the FRS. To our knowledge, this experiment is the first field application of MMR for CO2 monitoring. The aim of the survey was to evaluate the noise conditions at the site and determine the optimal data acquisition parameters, in addition to providing baseline data for a monitoring program.
