ABSTRACT:
Method and system for calculating resistivity of an earth formation. At least some of the illustrative embodiments are methods comprising transmitting a current from a first current source, receiving at least part of the current at a first current return, said first current disposed remotely from the first current source, and measuring a first voltage at a monitor electrode, said monitor electrode disposed more remotely from below the first current source than said first current return.
