UBHO Sub

Overview

A Universal Bottom Hole Orientation Sub is run below the drill collar to house the MWD/LWD tools. It is also called the mule shoe sub, because the mule shoe sits in the bottom of this sub. The mule shoe is used to orientate the MWD string downhole. The sub is manufactured as non-magnetic so it won't interfere with downhole electronics.
