WellFi

Know the
Unknown.

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 pulse 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. An isolation sub creates the antenna gap, the tool sends data through the surrounding formation, and the surface receiver hands the decoded readings to MODBUS RS-485 or 4-20 mA.

  1. 01

    Create the antenna gap

    An isolation sub electrically separates the tubing string.

  2. 02

    Transmit through the formation

    The downhole tool sends a low-power electromagnetic signal without a new cable.

  3. 03

    Decode at surface

    A surface receiver and ground reference recover the telemetry.

  4. 04

    Connect to operations

    Readings land on MODBUS RS-485 or 4-20 mA for the existing RTU or SCADA system.

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.

THE TOOL

Inside the string.
Out of the way.

WellFi attaches to the interior or exterior of the tubing, on new installs or pump changes. It reports over wireless electromagnetic telemetry, which removes the risk that comes with running a cable.

COMMON QUESTIONS

Before you ask.

Does WellFi need a downhole cable?

No. WellFi sends a low-power electromagnetic signal through the formation to a surface receiver. An isolation sub creates the antenna gap in the tubing string, so there is 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 attaches to the interior or exterior of the tubing. 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.

Proudly Indigenous Owned

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.
