Abstract

A system for ranging between two wellbores where an emitter electrode and return electrode of a current injection system are disposed to drive a current to a conductive member within a target wellbore to create an electromagnetic field about the conductive member. The electromagnetic field is measured utilizing a sensor disposed in an investigative wellbore, which may be in the process of being drilled. In some embodiments, the emitter electrode and return electrode are positioned on the surface of a formation, spaced apart from one another with locations on the surface selected to optimize current, and therefore, the electromagnetic field, at a desired point along the conductive member. In some embodiments, one or both of the emitter electrode and return electrode are positioned in the target wellbore.
