Ancilliary Item

Orientation Mule-Shoe

An Orientation Mule-Shoe is a required component for effective downhole navigation surveying with the DeviGyro RG40 or DeviShot instruments, in the navigational drilling application.

Orientation Mule-Shoe

Attached to the bottom of the survey instrument, the Orientation Mule-Shoe has a landing sleeve that enables the survey instrument to align with the correlating pin inside the downhole motor or wedge (methods of Navigational Drilling). This process establishes the “high-side tool-face” of the survey instrument, which is essential for knowing the orientation of the downhole motor or wedge.

Combined with the advanced DeviGyro and DeviShot
technology, the drill crew is effectively provided with the true orientation and positional data they need, in a timely manner, to be confident they are on plan and beginning the Navigational Drilling alteration correctly.
