DEFINITION

Classification: 324/347

Using electrode arrays, circuits, structure, or supports:

(under subclass 323) Subject matter relating to means for introducing electric currents into the subsurface or for collecting electric currents from the subsurface by conduction.

(1) Note. This subclass includes the structure or configuration of one or more electrodes and the means for supporting such electrodes. The electrodes and their supports are primarily of the borehole type, although not limited thereto.
