The Specification discusses the application of these measurements to the computation of conductivity distribution, viz: - (i) Figs. 2, 3 (not shown) illustrate that if # v  is inside the curve of Fig.3 (not shown) (as point 36) conductivity nearer the probe is less than that further away, and conversely if the point is outside the curve (e.g. as at 38).(ii) The derivation of a mathematical formula from which # u  and # v  can be calculated (corrected for skin depth effect) is given for a single coil array and also for a multi-coil array Fig.3A (not shown). These equations may be solved by conventional analogue computing techniques e.g. as illustrated by block-diagram Fig.4 (not shown). Alternatively successive approximation technique may be used with assumed values of # u +# v  checked with a digital computer against actual readings. (iii) The response at different radial and vertical positions relative to the probe coil array (Geometrical Factor) is described with reference to Figs. 6 and 7 (not shown); and (iv) the # v  signal as the probe is lowered through seven layers of varying conductivity is illustrated, Fig. 8 (not shown); (v) the estimation of radial conductivity distribution at different depths is described with reference to Figs.9, 10 (not shown) together with block diagram computor circuits, (vi) a simplified computational technique using cartesian instead of radial correction factors for skin effect, Figs.12, 13 (not shown).
