CO₂ Monitoring

A secure and reliable Measurement, Monitoring and Verification (MMV) scheme is required to store CO2 safely. Stored CO2 has an electrical resistivity that is saturation dependent and will differ significantly from surrounding water-filled formations. Using seismic only for monitoring would be difficult as seismic p-wave velocity is almost insensitive to increased levels of CO2 in a formation.

Our measured fields are highly sensitive to changes in electrical resistivity, making it ideal for detecting both change in volume and lateral expansion.
