WellFi wireless downhole telemetry
WellFi is a wireless downhole telemetry tool that reports pressure, temperature, vibration and produced-fluid condition to surface. It sends its readings up through the formation itself by electromagnetic telemetry to a receiver at surface, so there is no downhole cable to run, clamp or damage.

What it measures
| Channel | What it reports |
|---|---|
| Pressure | Pump-intake and reservoir response pressure at the lift point |
| Temperature | Temperature trends at tool depth and operating interval |
| Vibration | Pump and string vibration changes, before abnormal operation escalates |
| Fluid composition | Produced-fluid composition changes from the tool location or paired layouts |
| Flow insight | Interval behaviour interpreted from paired pressure and fluid-condition trends |
Specifications
| Property | Value |
|---|---|
| Pressure rating | 10,000 psia |
| Temperature rating | 150 °C |
| Tool outer diameter | 46 mm |
| Battery life | 5+ years |
| Surface output | MODBUS RS-485 / 4-20 mA |
WellFi is rated to 150 °C. A higher-temperature version for thermal and SAGD service is in development and is not available today.
Installation
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. It can also be installed on its own run.
Where it fits
It suits heavy-oil wells on progressing cavity pumps, including cold-production open-hole multilaterals in the Clearwater and Mannville.
WellFi is a production monitoring tool. It is not an MWD/LWD drilling service, not a wireline logging service, and not sand-control or flow-control hardware.
Data path to surface
- The tool sends its readings up through the formation by electromagnetic telemetry.
- 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.
