14. A method of determining a relative location between two points in a well system, the method comprising:
installing a well shoe device into a cased drilled well at a first location, wherein:
the well shoe device includes at least one element capable of generating a magnetic field,
the at least one element capable of generating a magnetic field is located in an interior of a hollow rigid outer shell of the well shoe device that fully encloses the at least one element, and
the magnetic field is energized by an excitation source; and
determining a relative location of the well shoe device, utilizing a measured magnetic field, by a ranging receiver located at a second location in the well system.
