RESISTIVITY CORRELATION IN WELLS In discussing the results which have been obtained on structure with the resistivity and potential-drop-ratio methods the experience obtained by measuring resistivities in wells should by no means be overlooked. In the first place, the results obtained by determining the resistivities in situ at the depths reached by the drill, give very 483
