Effective foundation for an abandonment cement barrier

The industry-unique ProMILL system enables consistent savings during P&A operations by delivering in a single run what has typically taken four trips to accomplish.

The ProMILL system combines a bridge plug assembly, a section mill, and a high ratio underreamer to prepare the foundation for an abandonment cement barrier in a single run. During the run, it eradicates all leak paths from the abandonment barrier while achieving rock-to-rock zonal isolation.

All ProMILL system cutter arms are dressed with Wav-Edge™ ridged milling elements that, along with the multiblade design, provides high ROP and maximizes footage. This unique milling element, designed with a concave pattern and narrow leading edge, has improved durability, stabilization, and results in superior hole cleaning and swarf quality.

The high-ratio underreamer features ball-drop activation, which ensures that the reamer remains inert during the entire milling operation. The section is underreamed and the operator achieves the target access, completing the operation.
