Project goals

Project goals

  • 01

    Validate FRS in oil-based mud (OBM)

  • 02

    Validate operation at temperatures up to 115°C

  • 03

    Reduce torque and hook load on a long horizontal section

  • 04

    Build headroom for longer horizontals

Solution

Technology

FRS

FRS-102, type 1
FRS — Friction Reduction System

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.

01

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.

02

Friction coefficient < 0.06

Low-friction composite — Kompozit №1. For reference: steel on steel runs at 0.13 in the lab. 2×+ less friction.

03

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.

Takeaways

Conclusions and lessons

  • 01

    OBM at 115°C

    Done

    FRS confirmed reliability in cased hole, oil-based mud, at temperatures up to 115°C.

  • 02

    Headroom for longer horizontals

    Open

    Slide drilling now has up to +500 m of headroom for horizontal extension.

Equipment

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.

Engineering

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.

Field support

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.

Get in touch
We reply within a day

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.
