Well Field test №7
Horizontal well at 88° with 2,528 m reach. Transit and horizontal sections on a 2-string design, extended by 200 m with a motor BHA. Pre-job analysis flagged the well as undrillable from 3,830 m.

Project goals
- 01
Drill transit and horizontal sections (2-string), extended by 200 m
- 02
Beat the calculated undrillable point at 3,830 m
- 03
Transfer enough load on directional drilling
- 04
Avoid incidents during directional drilling from 3,450 m
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 — Kompozit №1. 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
Friction reduction confirmed
DoneTorque and hook load readings confirm FRS friction reduction.
- 02
Load transfer on directional drilling
DoneAdequate load transfer on directional drilling — no issues on either directional or rotary drilling.
- 03
Run completion
DoneRun ended at TD 3,990 m by geology call. All project goals delivered.
We build FRS to your project conditions
We design and supply friction reduction systems for drilling. Tools are engineered for real well conditions and run as part of an engineering plan.
We run T&D — we don't guess
We work through the well data, constraints, and risks. The output: a configuration you can defend and a clear plan for the run.
We're on the rig with you
We support the project on site — align the run scenario, tune parameters, capture the result, and roll the learnings into the next well.
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.
