ABSTRACT:
In the representative embodiment of the invention disclosed herein, an electrical logging tool is arranged to include an axial body around which a plurality of annular electrode members and insulating members are alternately stacked to achieve a particular configuration of formation-measuring electrodes. Fluid seals are arranged between the annular members and the stack is compressed between the ends of the axial body for defining an oil-filled chamber within the tool body.
