The dipole-dipole resistivity survey has been applied towards reservoir delineation as well as resistivity monitoring of a producing geothermal field. Resistivity monitoring may be sensitive to fluid extraction from the reservoir, reinjection of cooler fluids, or porosity reduction resulting from calcite precipitation. 
A primary advantage of the dipole-dipole electrode array is the ease of deployment in the field due to shorter wire lengths. However, a large generator may be needed to transmit a greater current magnitude for the measurement, especially for deep soundings.
