Apparatus (206), systems, and methods may include a magnetic dipole transmitter (103) to be located in a ranging well (100). A voltage measurement device can include a plurality of probes where each probe is to be located on one of a target well (120), the ranging well (100) or a surface (904) of a geological formation comprising the ranging well (100) and the target well (120). A controller (201) coupled to the voltage measurement device calculates a distance or relative direction between the target well (120) and the ranging well (100) based on a voltage difference between the plurality of probes. The distance/direction can be used to control drilling operations. Additional apparatus (206), systems, and methods are disclosed.
