FAST-R Underreamer
Field-proven and fail-safe technology for any
underreaming application

Resources
The FAST-R™ underreamer is the latest underreaming solution from ReedHycalog that allows ball drop and flow control options for any multi-cycle application. Built on our reliable Anderreamer™ platform, the FAST-R underreamer design utilizes premium ReedHycalog™ polycrystalline diamond compact (PDC) technology and an advanced hybrid cycling mechanism to complete underreamed intervals faster than ever before. This combination of high-performance features is unique to the FAST-R underreamer and the addition of numerous fail-safe mechanisms makes the FAST-R underreamer the best available design for one-trip underreaming applications.
Features and benefits
- Fast and simple flow control cycling
- Short and unique pumps off and on sequence to change tool position.
- Clear pressure signals
- Nozzle opens or closes when changing positions.
- Never gets lost
- Pumps off for several minutes to reset back to home/default tool setting.
- Eliminates short trips and ledge tests to verify tool position.
- Field-proven reliability
- Utilizes the existing Anderreamer™ tool body and cutter block expansion system.
- Reduces non-productive time (NPT)
- No accidental cycles at connections and pump or pressure issues won’t change tool position.
- Blocks will never get stuck open
- Three fail-safe cutter block retraction mechanisms: spring, overpull, and pump closed.
- Numerous bottomhole assembly (BHA) placement options
- Oversized thru-bore for wired connection with directional tools or IntelliServ™ wired drill pipe.
- Run the FAST-R underreamer in tandem with ball drop tools as second reamer or expandable stabilizer.
- Hybrid cycling mechanism options (flow + ball drop)
- Shoe Driller – Never trip due to activation issues. Drillout while closed, drop ball to activate, then flow cycling after.
- Lock Closed –Improve or expand hole cleaning techniques after reaching total depth (TD). Drop ball to lock the tool closed for the remainder of run.
- 3D (Multidiameter) – Reams cement sheath at intermediate diameter, then drop a ball for full expansion.
- Compatible with IQ Monitoring System™
- Cutter block sensors record PDC wear, position, and vibration.
- QUIQ™ analysis app provides critical run information minutes after downloading data.
