Abstract
A wellbore positioning system includes a first wellbore casing element bearing a first magnetic pattern that encodes first information associated with the wellbore or a drone. The first wellbore casing element is configured for placement down-hole in the wellbore. The first wellbore casing element extends along a central axis and defines an axially oriented passage. Also, the system includes an untethered drone configured for relative movement in the passage of the first wellbore casing element. The drone is configured to detect the first magnetic pattern and determine a position of the drone within the wellbore based on the first information.
