Well 8873G (2КК)
Double-string design (2-string casing). 90° horizontal, 1,736 m reach, open hole. With FRS, slide ROP went from 20 to 30 m/h.

- 03
Lift slide ROP
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
Open hole
DoneFRS confirmed reliability in open hole on a double-string design with mud motor on WBM.
- 02
Slide ROP lift
DoneBelow 3,000 m, slide ROP trends up — FRS reaches its effective high-side-load zone.
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.
