Product Sheet Reamaster Underreamer 16000 Series
22-in opening diameter; 16-in collapsed body diameter.
Forged cutter arm underreamer
With the ability to withstand high shock and torque loads and to run more drilling weight on the tool, Reamaster-XTU underreamer lets you spend more time on bottom for more cost-effective underreaming.
The Reamaster-XTU underreamer's large, robust cutter arms facilitate an increased cross-sectional area at the underreamer cutter pockets. The design also provides more room for larger sealed-bearing and polycrystalline diamond compact (PDC) cutters for optimized underreaming performance. A positive lock keeps the arms in the open position. The ability to enlarge an existing pilot hole by up to 70% makes this product ideal for a range of drilling and remedial operations.
Gun-drilled ports through the Reamaster-XTU underreamer deliver more fluid, giving the operator greater control over the distribution of fluid across the bit and the underreamer cutters. Hole cleaning efficiency is improved, and the fluid requirements of other downhole tools are accommodated.
Customized cutting structures are available for a broad range of applications and formation types. Sealed-bearing milled tooth and tungsten carbide insert (TCI) cutters are designed specifically for underreaming operations and are capable of delivering penetration rates and cutting structure lives, comparable with the drill bit. PDC cutters are also available for long intervals.
