Critical Well Abandonment Success in Colombia

When a high-stakes well abandonment operation in Colombia demanded precision and environmental care, innovation took center stage. This is the story of how advanced technology and strategic ingenuity turned a complex challenge into a pioneering success.

Tackling a Complex Challenge

When Colombia’s leading National Oil & Gas Operator faced a tough Plug and Abandonment (P&A) operation, they called on Wellbore Integrity Solutions (WIS). The mission? To achieve a precise and environmentally friendly extending length section milling interval for 9-5/8 inch and 13-3/8 inch casings. Speed and minimal impact were non-negotiable.

Cutting-Edge Solutions

WIS delivered with the 8000 series ProMILL? Duo system. First up was the 8200 ProMILL?, slicing through the 9-5/8 inch inner casing. Its partner the ProMILL? Underreamer, cleaned up the residual cement, cutting down rig time and complexity.

Next, the 8000 series ProMILL? Duo milled the 13-3/8 inch outer casing, followed by the ProMILL Underreamer’s borehole enlargement. This sequence ensured a strong rock-to-rock barrier, critical for lasting success.

Technology That Makes a Difference

Central to this operation was our WavEdge? Cutter Technology within the ProMILL? Duo Section Mill. Its unique cutter design boosted durability, rate of penetration, hole clearing, and swarf quality, making the process more efficient and effective.

Stellar Results

The operation’s outcomes were notable:

• Smooth Execution: Complied with local environmental standards and executed efficiently.
• Flawless Technology: Multiple technologies performed perfectly.
• Historic Milestone: First successful run of the ProMILL? Duo System in the Western Hemisphere.
