ABSTRACT:
Calculating resistivity of an earth formation. At least some of the illustrative embodiments are systems including: a first current source current return (CSCR) pair, said first CSCR pair comprises a first current source and a first current return, the first current return receives current from the first current source; a second CSCR pair, the second CSCR pair disposed along a longitudinal axis of said apparatus from the first CSCR pair, the second CSCR pair comprises a second current source and a second current return, and the second current return receives current from the second current source; and a monitor electrode disposed between the first CSCR pair and the second CSCR pair, a distance between the first current source and the monitor electrode is substantially equal to the distance between the second current source and the monitor electrode, and the monitor electrode monitors a first voltage and a second voltage.
