ABSTRACT:
Drill stem elements and connections are shown with advantages such as being mechanically robust. The absence of a side access window in a sonde housing is one design feature that provides robust mechanical properties. Further advantages of sonde housings include being easy to disassemble for access to the sonde unit, or for insertion of the sonde unit. In one embodiment, a cap portion is easily secured or removed using a small allen wrench, or a hammer and a punch. The cap portion is not substantially affected or tightened by rotation of the drill stem during a drilling operation. A further advantage includes the ability to remove cap portions and pull back flexible product such as polyethylene pipe from a small exit pit.
