# Yotin Energy > Indigenous-owned energy services company based in Pierceland, Saskatchewan, > serving the heavy-oil and oil sands corridor across Western Canada. Yotin > supplies WellFi, a wireless downhole telemetry tool that reports pressure, > temperature, vibration and produced-fluid condition to surface with no > downhole cable. The name comes from *yôtin*, the Cree word for wind — a force that crosses the land without being seen. WellFi works on the same principle: what cannot be seen can still be measured. ## Availability (updated 2026-09-29) The current WellFi batch is sold out. The next batch is due at the end of October 2026. The homepage's "Join the waitlist" form (https://yotinenergy.com/#waitlist) holds a place on the next batch; it needs only a name and a work email. ## What WellFi is used for - Cable-free downhole telemetry on producing wells: pressure and temperature readings travel from the lift point to surface without a downhole cable or fibre line to run, clamp or damage. - Instrumenting a well during work that is already scheduled - a progressing cavity pump changeout, a workover, or a new completion - so no separate intervention is needed. - **Heavy-oil production monitoring in Alberta and Saskatchewan**: pump-intake pressure, pump and string vibration, and produced-fluid and water-cut trends. - Heavy-oil wells on progressing cavity pumps, including cold-production open-hole multilaterals in the Clearwater and Mannville. - Sending downhole data to an existing SCADA or RTU over MODBUS RS-485 or 4-20 mA, without new control-system software. Scope note: 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. Yotin's currently offered product line is WellFi. ## Product: WellFi Wireless downhole telemetry. The tool 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. ### Measured channels | 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 | | Deployments | 160+ installed internationally | ### 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. ### Data path to surface 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. ## Company - **Legal / trade name:** Yotin Energy - **Ownership:** Indigenous-owned - **Relationship to WellFi:** exclusive Canadian distributor - **Head office:** Pierceland, Saskatchewan, Canada - **Area served:** Western Canada - the heavy-oil and oil sands corridor - **Focus:** cold heavy-oil production wells; field service through install and beyond ## Contact - Email: sales@yotinenergy.com - Phone: +1 403-679-5330 - Web: https://yotinenergy.com/ For anything else, call or email Yotin directly. ## Pages - [Home](https://yotinenergy.com/): company overview, WellFi channels, specifications, installation, FAQ, waitlist for the next batch - [WellFi specifications](https://yotinenergy.com/wellfi): channels, specifications, installation and data path - [Privacy notice](https://yotinenergy.com/privacy): what the site collects and why ## Notes on figures - The deployment figure is 160+ installed internationally. - Numeric readings on the website's channel cards (for example 2600 kPa or 4.2 mm/s RMS) are representative illustrations, not live measurements, specifications or performance figures. - Casing-size compatibility for the strapped configuration is confirmed well by well; no single casing-size limit is published. - WellFi is rated to **150 °C**. A higher-temperature version for thermal / SAGD service is **in development** and is not available today.
