The Gearhart REDBACK? Drilling Roller Reamer is a unique tool that is the result of a research & development program launched by GEARHART UNITED PTY LTD, Australia to develop a roller reamer that is reliable and durable enough to be picked up as part of the drilling BHA. The intention was to provide an effective solution to drilling-torque related challenges, which are commonly created by stabilizers rotating in a poor hole-quality borehole or when drilling long step-out directional wells. Client identified benefits when Redback Roller Reamers have been run in their BHA?s :- ? Reduced Drilling Torque - provided by the low friction contact area of the reamer tools, ? Improved Rotary Steerable performance - lower drilling torque allowing a higher RPM capability. ? Reduced Trip Times - due to improved bore wall geometry ? Reduced Stick Slip and Resultant Vibration - leading to longer bit life and improved performance. ? Improved ROP - better weight transfer provides a more constant energy level (WR) at the bit. ? Extended Meantime between Failures due to reduced torsional vibrations ? Improved Acoustic Log Quality - due to reduced torsional vibration ? Reduced Casing Running Times - due to improved bore wall profiles ? Extended Well Bore Reach - due to reduced torque and tortuosity. Please see www.redbackdrillingtools.com for further information
