2 Tool Preparation
2.1 Reviewing Tool Paperwork
The Rotary Steerable Outgoing Systems Test (OST) paperwork is a valuable document for the Directional
Driller. This paperwork will be provided by the Extreme Equipment Rental coordinator by the time tools
arrive on location. If not, contact the coordinator with the tool serial number so that the correct paperwork
can be provided. The tool serial number is stamped in the junk slot area of the bias unit, between two of
the PowerDrive pads as shown below.

capable of transmitting PD data, confirm this does
not say “Non RealTime” or “NRT”.
6. Gamma – Verify the tool contains a gamma
sensor if logging is planned.
