5. Once the flow restrictor is in place, re-insert the thread protector. 6. Note - Some NOV drill bits have a larger ID on the pin which may make it possible for the flow restrictor to fall into the drill bit while drilling. Make sure when on the rig floor that the thread protector is not removed until well hole is covered.

WITS Decoder The WITS decoder monitors live rig data and is used to confirm that a downlink sequence was carried out correctly. It is also used to transmit RST information via the internet to off-site operations personnel. The WITS decoder can be installed on any windows-based PC and requires a WITS feed containing live drilling data. While the WITS decoder is not required to operate the D-TECH tool, however it is highly recommended. The WITS decoder has the same algorithms that the downhole RST tool has in its Control Unit and is always looking for a possible downlink sequence and displays the most recent downlink sent to the tool.
