Downhole Pressure Monitoring System - Anvey Tubing Link
OVERVIEW
The Anvey Tubing Link™ DPG‑45 is an innovative cable‑free downhole pressure monitoring system designed for PCP wells, packer‑isolated completions, and long‑term production surveillance. This advanced system delivers real-time pressure and temperature data from either the tubing or annulus side without the need for electrical conductors, control lines, or wellhead penetrations.
At the core of this technology, a permanent-magnet generator in the downhole sub captures mechanical energy from the rotating drive system, which powers a piezoresistive, temperature‑compensated sensor housed in an oil‑filled, isolated cavity. The measured pressure and temperature are then transmitted acoustically through the tubing wall to a clamp‑on surface receiver.
On the surface, the receiver decodes the acoustic signal, outputting data via MODBUS serial communication, making it easily accessible for PLCs, RTUs, VFD panels, or SCADA systems. With a pressure range of 0–5000 psi, various metallurgy options for H₂S/CO₂, and the absence of downhole conductors, the Anvey Tubing Link™ DPG‑45 is the ideal solution for operators seeking enhanced downhole intelligence without the complexities of handling cables.
WHY CHOOSE ANVEY TUBING LINK
Real‑time downhole pressure and temperature—no conductors, no penetrations, MODBUS‑ready.
- No conductors or feedthroughs: No control lines, no cable logistics, no wellhead penetrations—simpler installation and fewer handling risks.
- Same data quality, easier deployment: Delivers dependable pressure/temperature data comparable to conventional gauges, but without cable complexity.
- Energy harvested downhole: Permanent‑magnet generator + rechargeable storage = continuous operation, even though shut‑ins.
- MODBUS serial output at surface: The receiver provides MODBUS RTU/TCP data, ready for direct integration with SCADA, PLCs, and VFD control systems.
- Ideal for PCP and packer‑isolated wells: Perfect where operators want pressure above/below packers or at pump intake, but don’t want to run cables.
- Electronics fully isolated from well fluid: Oil‑filled, pressure‑balanced cavity protects electronics from produced fluids and solids.
- Acoustic telemetry through tubing wall: Clamp‑on receiver, no intervention, compatible with deviated and horizontal wells.
- High‑accuracy, temp‑compensated sensing: Stable pressure readings up to 5000 psi with temperature compensation.
- Lower operational friction: No cable failures, no feedthrough leaks, no conductor handling—simpler field life and lower OPEX.
