Technology
FRS
Frameless composite friction reducers. Installed on the drill pipe in zones of maximum side load. The pipe rotates inside a stationary composite sleeve pressed against the wellbore wall.
Plain-bearing principle
The drill pipe rotates inside a stationary composite sleeve. The sleeve is pressed against the wellbore wall or casing by lateral load — never touching the pipe body.
Friction coefficient < 0.06
Low-friction composite protector material. For reference: steel on steel runs at 0.13 in the lab. 2×+ less friction.
1–2 min to install
Mounts on the pipe during a trip or on the catwalk. Held by two stop collars. No steel frame, no hinges inside the sleeve.
Key results
Conclusions and lessons
- 01
Torque reduction
DoneRun #1: −32% (−12 kN·m). Run #2: −18% (−7 kN·m). Run #3: −20% (−8 kN·m).
- 02
Hook load on POOH reduction
DoneRun #1: −26 t vs forecast. Run #3: −10 t vs the BHA without FRS.
- 03
Surface vibration eliminated
DoneAllowable top-drive rotary speed raised from 90 to 140–160 rpm.
Equipment
We design and supply friction reduction systems for drilling. Tools are engineered for real well conditions and run as part of an engineering plan.
Engineering & analysis
We work through the well data, constraints, and risks. The output: a configuration you can defend and a clear plan for the run.
Implementation support
We support the project on site — align the run scenario, tune parameters, capture the result, and roll the learnings into the next well.
Forecast vs actual torque held within 8% — the T&D model proves out for sizing protector count and placement on long horizontal sections.
Run the numbers on your well
Send your well data and constraints — we'll run T&D modeling and come back with a configuration and the expected impact.
