2082046 9117437 PCTABS00008 Apparatus for assessing geophysical characteristics by measuring resistivity of a core sample comprises a first array (C1) of current electrodes, a second array (C2) of current electrodes, a constant current source and sink to pass constant current between the electrodes in the arrays (C1, C2), control means supplying substantially equal currents at each of the electrodes and second control means to ensure that the current received by the electrodes (C2) is substantially equally distributed between them. The illustrative apparatus further comprises a third array (P1-64) of potential electrodes adapted to be positioned at spaced intervals on a sample to be assessed. Computer records the results and controls operation of the illustrative apparatus.
