Introduction The AccuScribe tool is an automated, error-proof scribeline offset system that will replace the current method, which relies on human estimation and hand-written notes, leaving little room for ad hoc validation. A simple 1-2-3 process will allow the user to get precision readings in less than three minutes and store the image of the scribeline offset for later evaluation or troubleshooting. 1.1

9 Muleshoe / Sub Method – Part 1 (Target Housing) This method is intended to scribe zero degrees across long distances and is suitable for software that only carries zerodegree offsets.
The user will need to include the images taken in Step 3.10.
9.1
Torque up the mule shoe sub or the UBHO to the BHA, as per API standards.
9.2
Using a soft cloth, clean/wipe all surfaces around the predicted high-side of the Muleshoe to remove any debris or liquids.
9.3
Add a vertical high-visibility mark at the predicted high-side of the mule shoe, using a pen, chalk, or other suitable method. The temporary high-side mark should be made within the vicinity of the mud motor high-side. This mark must be within 90° in order to use the protractor seen on the camera ring mount and should preferably be as close to 0° as possible.
