Note:

Drill Collar Severing Tools are designed to sever drill collars and heavyweight drill pipe reliably and safely during Pipe Recovery Operations.

Executive Summary

Drill Collar Severing Tools are used to sever drill collars and heavyweight drill pipe reliably and safely during pipe recovery operations. The tool operates using Explosive Bridge-Wire (EBW) Detonators that initiate simultaneous detonations of explosive columns, generating a colliding shock wave that cuts through the tubular with precision.

EBW Detonators provide accurate timing and increased control of the explosive sequence, ensuring consistent and efficient performance. Tension is typically applied to the tubing before detonation to assist in freeing stuck tubulars.

Drill Collar Severing Tools are applied in pipe recovery, stuck pipe, and plug and abandonment (P&A) operations where controlled, precise severing of downhole equipment is required.

Detailed Description

Drill Collar Severing Tools are used for pipe recovery operations to sever drill collars and heavyweight drill pipe. The tools utilize Explosive Bridge-Wire (EBW) detonators to simultaneously detonate explosive columns, creating a colliding shock wave that severs the tubular with precision.

The tools conform to API RP-67 and are suitable for stuck pipe and plug-and-abandonment (P&A) operations. Detonators are air shippable, and hardware is shipped separately, with assembly performed on location to ensure safe handling and deployment.

EBW detonators increase the precision of the colliding shock waves, providing consistent and controlled severing of tubulars. Tension is typically applied to the tubing prior to detonation to assist in the removal of stuck tubulars and to improve the efficiency of the operation.

These tools are applied in scenarios where accurate, controlled severing is required to recover or remove downhole tubular components safely. They are suitable for a range of tubular sizes and are designed to maintain reliability under the conditions commonly encountered in deepwater, high-pressure, or deviated wellbores.

Drill Collar Severing Tools provide a reproducible method for severing tubulars while minimizing risk to personnel and equipment. Their use ensures that stuck or abandoned tubulars can be removed in a controlled manner, supporting safe and effective pipe recovery operations.
