DUAL-STRING SECTION MILL

The Rock’s dual-string section mill efficiently exposes the wellbore to the bed rock for a better cement-to-formation bond which features a high expansion ratio and is run in a separate trip with an Expandable Stabilizer to drift through a smaller casing and mill a section in the outer casing.

Features:

• As part of the comprehensive plug and abandonment systems portfolio, the section mill greatly improves efficiency and reduces cost in a dual string application by eliminating the need to mill up the inner string from the surface or top of cement, when a section needs to be milled in the outer casing for setting a cement plug.

• Multiple trips to mill up the inner casing are eliminated, due to the small drift of this tool and the high expansion ratio.

• The inserts cut out radially and axially downward to improve milling.
