The orientation mule shoe sleeve is
assembled in the drill string allowing
the orientation mule shoe to locate
into the sleeve at a common orientation
for each survey. The internal pin
leaves an impression on the tell-tale
in the orientation mule shoe; this
confirms that the mule shoe has located
in the same orientation on each survey.
The survey system assembly generally
has 9 metres of non-magnetic drill
rod fitted directly above the mule
shoe sleeve; this positions the survey
tool approximately 4.5 metres from
either the down hole motor at the
bottom, or the steel drill rods at
the top of the drilling assembly.
