A bstract The method of field differences using two parallel bipole sources is described. The system possesses much greater resolving power and investigating depth than the conventional Schlumberger configuration. Of the two variations, the longitudinal field difference has about two and half times greater depth of investigation than the transverse one. Practical advantage of the present technique over the Schlumberger system in reducing the ambiguity in interpretation due to equivalent layered structures is demonstrated on a theoretical example.
