4 Assembly of the Drill Collar Severing Tool
4.1 Safety Procedures
JRC Drill Collar Severing Tools are shipped disassembled to allow for preferable
transportation methods. Upon delivery to the end user destination, the DCST can be
assembled in preparation for deployment into the well.
Ensure all required materials are identified and on hand before proceeding with handling of
the explosive components. Quantity and shape of explosive components in the kit is
dependent on DCST size.
The DCST may use a Resistorized detonator, which reduces the possibility of accidental
firing by stray current, or a Top Fire, RED detonator; that provides additional safety
enhancements when compared to conventional Resistorized detonators. All previously
established safety rules and regulations should be maintained during the assembly of
explosives.
