Abstract
In a resistivity logging system, the preferred and illustrated embodiment features a downhole well logging tool utilizing central current emitting electrode flanked symmetrically with a number of small electrodes above and below the central electrode. A switching system is included for switching symmetrical pairs of electrodes into parallel with the central electrode thereby increasing the effective field acting on the current flow. The current flow penetrates radially outwardly into the earth's formations in relation to the relative length of the array of electrodes, thereby enabling a sweep to yield borehole resistivity and deep formation resistivity. The data is preferably presented in a resistogram profile.
