Drilling and Pinning

The Claxton drilling and pinning system provides an efficient method for securing multiple casing strings for safe recovery operations.

The drilling and pinning system can be provided as part of a package that includes rapid cut bandsaws for severance and hydraulic jacking systems for recovery. It enables simultaneous retrieval of multiple casing strings, and is designed to work independently of rig operations.

As a cold work technique it is especially suited to abandonment operations where adjacent wells may still be in production. Features of our drilling and pinning portfolio include:

• Single drilling units available for applications where space is restricted
• Double drilling units available for simultaneous boring of both sides of the conductor and casings
• Modular design with multiple handling points for ease of installation and operation
• All units certified for zone II applications
• Conductor end caps provided to mitigate dropped object potential

Crucially, when compared to conventional methods, using our system to drill, pin and recover the conductor means less deck space is required for the recovered casings – meaning disposal logistics are simplified and costs reduced.
