Abstract
A theory for the bipole‐dipole method of resistivity sounding is developed. Bipole‐dipole apparent resistivities are related to Schlumberger apparent resistivities at two spacings. The theory can also be used to compute exact dipole‐dipole apparent resistivity curves providing an improvement over the existing techniques which involve far field approximations. A comparison of bipole‐dipole and dipole‐dipole systems reveals the similarity between the two. However, the resolution of the bipole‐dipole system depends on the azimuth angle. The flexibility of the theoretical expressions lead to a generalized field scheme independent of the bipolar or dipolar nature of the current source.
