ERT method shows link between CO2 gas dissolution and electrical resistivity.

ERT method also shows link between CO2 supercritical gas saturation and resistivity.

A focusing inversion approach enhances imaging of the inter-well region.

Comparative 2-D and 3-D imaging studies reveal potential 2-D inversion artifacts.

3-D inversions of Cranfield ERT data support previous hydrological findings.
