Core Laboratories recently supported a plug and abandonment operation using its Pulverizor™ system. This proprietary system provides operators with an efficient alternative to conventional section milling for barrier placement.
Plug and abandonment operations often require access to annular spaces to install permanent cement barriers. Traditional section milling can be time consuming and operationally complex, often requiring extended rig time and additional intervention steps. Technologies that simplify access to the annulus can significantly improve operational efficiency, reduce operational risk, and enhance overall reliability.
“The Pulverizor system is the most versatile multi-purpose solution for P&A casing recovery and SAP-B challenges, enabling efficient barrier placement and/or enhanced removal, reduced risk, and adaptability across complex well conditions”
Craig Smith, Technical Services Manager
Core Lab deployed its Pulverizor™ perforating system in a tubing-conveyed configuration to pulverize annular cement in 7-inch casing. The system uses targeted pressure pulses generated by PAC™ and PLV charges to break up cement while avoiding penetration beyond the outer casing. This process creates a clean pathway that enables the placement of permanent cement barriers during abandonment operations.
Approximately 200 feet of Pulverizor™ technology was deployed across two intervals, enabling efficient placement of both deep-set and shallow cement barriers. The operation was completed successfully, demonstrating the system’s ability to provide reliable annular access while minimizing the mechanical complexity commonly associated with traditional milling techniques. By reducing operational steps and improving deployment efficiency, the Pulverizor™ system continues to offer operators a practical solution for challenging abandonment environments.
In recognition of its innovation and field performance, the Pulverizor™ system received the 2025 Offshore Well Intervention Global Award for Plug & Abandonment Innovation, highlighting its role in advancing plug and abandonment operations.
