Hor 90° · Eastern Siberia

Well 2I

Horizontal well at 90° — the most challenging profile on the project, 3,200 m reach. FRS-89 in open hole let the team skip the oscillator and reach TD 3,600 m.

Project goals

Project goals

  • 01

    Drill horizontal with a mud motor, no oscillator

  • 02

    Maximum horizontal displacement (HD) to target

  • 03

    Beat the calculated torque limit of 29–30 kN·m (close to make-up torque)

  • 04

    Reduce hook load on POOH

Solution

Technology

FRS

FRS-89
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

    Oscillator dropped

    Done

    Without FRS, torque would have run at 29–30 kN·m — right up against make-up torque. Rotary drilling would have been capped. With FRS, rotary drilling ran unconstrained.

  • 02

    Torque trend

    Done

    Actual torque tracks the FRS-aware forecast curve. Trend break visible at 3,800 m — from rising to flat.

  • 03

    FRS working — confirmed

    Done

    Wear marks on the pipe prove FRS is working: the pipe rotates inside a stationary sleeve.

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.

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.
