WellFi


Every well is already telling you what is happening downhole. WellFi is how you hear it — wireless, no cable, no dedicated trip. Run it on a new completion, a planned changeout, or any producer worth watching.

01

Signal

WellFi sends a low-power wireless signal from deep inside the well.

02

Measure

Pressure, temperature, vibration, and fluid-condition data are captured.

03

Insight

Live telemetry lands in the control system operators already use.

REAL-TIME WIRELESS DOWNHOLE TELEMETRY

Data Below.
Insight Above.

Pressure. Temperature. Vibration. At Surface.

WellFi can be added during a pump change or included in a new well. The tool sends its readings up through the formation itself, and the surface receiver hands them to MODBUS RS-485 or 4-20 mA.

THE TOOL

Inside the string.
Out of the way.

WellFi runs on the tubing string — made up into the string, or strapped to the tubing OD inside casing, subject to casing size — on new installs or pump changes. It reports wirelessly, which removes the risk that comes with running a cable.

WHY OPERATORS RUN IT

Benefits of WellFi

  • Extend Pump Life

    Know your hydrostatic, understand vibration, avoid pump failure.

  • Increase Production

    Run closer to optimal without flying blind.

  • Drawdown Management

    Set notifications to ensure your drawdown stays consistent.

  • Reservoir Monitoring

    See reservoir response at the lift point.

  • Track Fluid Changes

    Spot produced-fluid changes as they happen.

  • Well Optimization

    Reservoir-fluid monitoring that turns data into production efficiencies.

COMMON QUESTIONS

Before you ask.

Does WellFi need a downhole cable?

No. WellFi sends its readings wirelessly through the formation itself to a receiver at surface — no cable to run, clamp or damage.

What does WellFi measure?

Pressure at the lift point, temperature at tool depth, pump and string vibration, produced-fluid composition changes, and interval flow behaviour interpreted from paired pressure and fluid-condition trends.

How is WellFi installed?

WellFi runs on the tubing string — the collar is made up into the string, or strapped to the tubing OD inside casing, subject to casing size (confirm per well). It is most often run on a new completion or during work that is already scheduled, such as a planned progressing cavity pump changeout or a workover, so no separate intervention is required — but it can also be installed on its own run where a well justifies it.

How does WellFi data reach our control system?

A surface receiver and ground reference decode the telemetry and output it over MODBUS RS-485 or 4-20 mA to the existing RTU or SCADA system. The WellFi Access Portal also analyzes the data and returns recommendations on drawdown, vibration and produced-fluid trends.

ABOUT YOTIN Proudly Indigenous Owned

The name comes
from yôtin.

The Cree word for wind — a force that crosses the land without being seen. WellFi works on the same useful truth: what cannot be seen can still be measured.
