• The ProMILL Duo provides an innovative, cost-saving solution for well abandonment applications, where the integrity of the abandonment zone requires the creation of a milled section in two casing sizes. Significant rig time savings are realized when using the ProMILL Duo in comparison to conventional solutions that require a long, inner string casing to be milled.
  • The high expansion ratio of the ProMILL Duo Section Mill allows it to drift through the inner casing in the retracted state and upon actuation, open up to a larger diameter to mill the outer casing and the coupling.
  • The ProMILL Duo expansion mechanism is based on a proven spline-based actuation platform with a long history of durability and performance. Similarly, the cutting structure on the arms is dressed with WavEdge* ridged milling elements that have demonstrated performance in the ProMILL system. The system also includes an active stabilization module that optimizes the dynamic behavior and reduces the vibration of the BHA during operation.
  • The enlargement of the borehole, to enable a rock to rock barrier is accomplished by using the ProMILL Underreamer (PMUR). The PMUR provides a market-leading expansion ratio and is designed specifically for well abandonment applications. It incorporates a robust cutter arm mechanism
    and the latest cutter technology to optimize performance

Completes a key technology gap in the Well Abandonment portfolio:

  • Differentiating technology
  • Offers significant rig time and cost savings associated with long inner string milling operations
  • Ideally suited to Well Abandonment applications where poor cement quality exists in the B and C annuli
A new platform that incorporates proven features:
  • Spline based deployment of block and cutter arms
  • Incorporation of WavEdge cutting structures
  • Active Stabilization
  • High expansion ratio
