Wellhead Electrical & Automation

Wellhead control, power and SCADA, engineered as one system.

Fennec designs, installs and maintains wellhead control panels and emergency shutdown systems, the VFDs and power infrastructure behind ESPs, and the RTU/PLC and SCADA links that bring every well onto one screen.

03.ASystem view

One signal path, from the gauge to the control room.

We engineer each layer to work with the next: downhole data reaches SCADA, and a shutdown command reaches the valve.

    • SCADA

Data flows up, from sensors to SCADA. Control and shutdown commands flow down, from SCADA to the valves.

03.1Control & shutdown

Panels that shut the well in safely, every time.

Design, installation and maintenance of the safety layer at the wellhead.

Wellhead control panels (WHCP)

Hydraulic and electrical panel design, build supervision, installation and maintenance.

ESD & HIPPS

Emergency shutdown and high-integrity pressure protection logic and hardware.

SCSSV / SSV control

Control of subsurface and surface safety valves from the panel and from SCADA.

03.2ESP electrical infrastructure

Clean, controllable power down to the pump.

The electrical chain that decides ESP run life.

Variable frequency drives

VFD selection and setup for submersible pumps, including soft start and speed control.

Wellsite transformers

Step-up transformer sizing and installation for the wellsite.

Downhole power cables

Cable selection and specification for the depth, temperature and load of the well.

03.3Automation & remote operations

Every well visible from the control room.

Monitoring and control from downhole sensor to SCADA screen.

RTU / PLC

Wellsite controllers configured for monitoring, alarms and control logic.

SCADA integration

Connection of wellsite units to the central SCADA system for real-time control.

Downhole gauge systems

Pressure and temperature gauges that feed production and lift optimisation.

Technical noteWellhead control and SCADA integration: a layer-by-layer approachHow Fennec engineers the path from downhole gauges and safety valves to the control room, so data flows up and shutdown commands flow down.

Questions

Common questions

Can you connect existing wells to our SCADA system?

Yes. We survey the existing panels, drives and instruments, specify RTU/PLC hardware and communications, and integrate the wellsite into your central SCADA with the required alarms and controls.

Do you supply VFDs for ESP wells?

We select and specify VFDs, transformers and downhole power cable for ESP wells, and support installation, commissioning and maintenance.
