Abstract:
The patent describes a system and method for determining the electrical parameters of large samples of materials in situ. A set of linear electrodes in boreholes forms a square pattern positive and negative electrical potentials on alternate electrodes create symmetry planes which define several cells a given fraction of electrical current leaves an electrode and reaches a corresponding electrode and an impedance characteristic is determined for each cell. The presence of inhomogeneity and anisotropy is reflected by unequal currents in geometrically equivalent cells.
