Oil and Gas Control Panels

Control Panels for Oil & Gas Sites Where Safety, Environment, and Shutdown Logic Matter First

Uniregal supplies custom oil and gas control panels for wellhead control, pump skids, compressor packages, metering systems, fuel handling, remote stations, process monitoring, and hazardous-area-related control applications.
In oil and gas projects, the control panel is not only used to start equipment or display signals. It may need to support emergency shutdown logic, pressure and flow monitoring, valve status, remote communication, harsh outdoor installation, corrosion resistance, and clear maintenance access.
The first question is not “Can this panel be built?” The first question is “Where will this panel be installed, and what risk must it control?”

Quick Answer

An oil and gas control panel is an electrical or automation panel used to monitor and control equipment in upstream, midstream, downstream, or utility-related oil and gas applications.
It may handle pressure, flow, temperature, level, valve status, pump control, compressor auxiliary systems, emergency shutdown signals, remote telemetry, PLC/RTU logic, and SCADA communication.
For buyers, the key decision is whether the panel matches the site classification, environmental exposure, control philosophy, safety shutdown requirement, communication method, maintenance practice, and project documentation standard.

Start With the Installation Area

Oil and gas control panels should be specified according to the installation area before component selection begins.
Installation Area
Buyer Concern
Non-Hazardous Electrical Room
Standard industrial control panel design may be suitable if it only controls remote equipment
Outdoor Oilfield Site
Weather, temperature, dust, UV, cable entry and remote maintenance matter
Hazardous Classified Area
Ignition risk, enclosure type, wiring method and certified components must be reviewed
Offshore / Marine Environment
Corrosion, vibration, space limitation and access difficulty become important
Skid-Mounted Package
Panel must match package wiring, instrument layout and site interface
Remote Well Site
Low power design, RTU communication, battery or solar support may be needed
UL 698A is commonly associated with industrial control panels used in hazardous classified locations where flammable gases, vapors or combustible dust may be present. It does not replace ordinary industrial panel requirements; it adds another layer of hazardous-location safety consideration. UL 698A overview, UL 508A vs UL 698A

Main Control Functions

Function
Why It Matters in Oil & Gas
Emergency Shutdown
Equipment must move to a defined safe state when abnormal signals occur
Pressure Monitoring
High or low pressure can indicate blocked lines, pump issues or unsafe conditions
Flow Monitoring
Flow confirmation is often needed before pumps, dosing or transfer operations continue
Valve Position Feedback
Operators need to know whether critical valves are open, closed or failed to move
Local / Remote Mode
Field teams may need local control while SCADA or control room has remote visibility
Alarm Prioritization
Not every alarm has the same consequence; shutdown, warning and maintenance alarms should be separated
Communication
Remote oilfield sites often depend on RTU, SCADA, modem, router or gateway communication
Power Backup
Some sites may require UPS, battery or solar-supported control power
Harsh Environment Protection
Heat, dust, rain, corrosion and vibration affect enclosure and component selection

Gas / Fire Interface
Alarm contact or interface signal if required by project scope
Communication
Modbus RTU/TCP, Ethernet, serial, radio modem, cellular router, SCADA interface

PLC, RTU, HMI and SCADA

Oil and gas projects may use PLC, RTU, HMI and SCADA together, but they do not serve the same purpose.
System Layer
Typical Role
PLC
Handles local logic, interlocks, alarms, pump/valve control
RTU
Collects field data from remote sites and sends it to SCADA
HMI
Gives local operators status, alarms, setpoints and manual control
SCADA Interface
Provides remote monitoring, alarm visibility and historical data
Gateway / Router
Supports communication between site equipment and plant network
Remote oil and gas wellhead applications often require wide operating temperature range, low power consumption and reliable remote communication. These concerns appear frequently in RTU and wellhead control discussions. Yokogawa RTU wellhead reference

Wellhead and Shutdown Logic

Wellhead-related panels are different from ordinary machine control panels because they may be tied to safe shutdown behavior.
A wellhead control panel may monitor or interface with safety valves, pressure switches, solenoid valves, hydraulic or pneumatic actuation, local controls and emergency shutdown signals. WHCP discussions commonly focus on controlling wellhead valves and enabling safe shutdown during abnormal conditions or maintenance. Wellhead control panel selection reference
For these projects, the buyer should confirm:
Item
Why It Matters
Controlled Valves
Determines output type, power, pneumatic or hydraulic interface
Shutdown Philosophy
Defines what happens during high pressure, low pressure, fire/gas alarm or E-stop
Local Manual Override
Field operators may need controlled access during maintenance
Pressure Monitoring
Wellhead safety often depends on reliable pressure signals
SCADA / RTU Interface
Remote operators need status and alarm visibility
Fail-Safe State
The panel must support the project’s safe-state requirement

Testing and FAT Focus

For oil and gas projects, testing should focus on signal correctness and shutdown behavior, not only whether the cabinet powers on.
Typical inspection and FAT items may include:
  • Component model verification
  • Enclosure and nameplate inspection
  • Wiring continuity check
  • Grounding check
  • Terminal and wire label inspection
  • Control voltage check
  • PLC / RTU I/O signal check
  • Analog signal simulation when applicable
  • HMI alarm and status check when applicable
  • Communication check when applicable
  • E-stop and shutdown signal check according to agreed logic
  • Valve command and feedback simulation when applicable
  • Packing inspection before delivery

Retrofit and Replacement Projects

Many oil and gas control panel inquiries come from existing sites where equipment is still operating but the control system has become difficult to maintain.
The old panel may contain discontinued PLCs, unclear terminal labels, damaged relays, outdated RTU equipment, missing drawings or components that are difficult to replace locally.
For retrofit projects, buyers can send panel photos, PLC/RTU model, instrument list, wiring drawings, site area classification, shutdown logic notes and a description of the current operating problem. We can review the available information and suggest a practical replacement or upgrade configuration.

FAQ

What are oil and gas control panels?

Oil and gas control panels are electrical or automation panels used to monitor and control equipment such as pumps, valves, wellheads, compressors, metering skids, RTU stations and shutdown interfaces in oil and gas applications.

What makes an oil and gas control panel different from a normal industrial control panel?

The difference is usually the site risk. Oil and gas panels may need to consider hazardous area classification, outdoor exposure, corrosion, remote communication, emergency shutdown logic, pressure monitoring and strict documentation.

Can the panel be used in a hazardous area?

That depends on the area classification and certification requirement. A panel installed directly in a hazardous classified area may need explosion-proof or certified hazardous-location design. A panel installed in a safe area but connected to field devices in hazardous areas may need a different intrinsically safe or barrier-based strategy.

What is the difference between UL 508A and UL 698A?

UL 508A is commonly used for general industrial control panels. UL 698A is associated with control panels for hazardous classified locations and adds hazardous-location safety requirements. The exact requirement should be confirmed according to the project location and authority requirement.

Can you build PLC or RTU panels for oilfield sites?

Yes. PLC or RTU panels can be configured for remote monitoring, pump control, pressure and flow signals, valve feedback, alarm outputs and SCADA communication according to the project scope.

What information is needed for quotation?

Please send the application, installation area, hazardous area classification if applicable, instrument list, signal type, shutdown logic, communication requirement, power supply, enclosure requirement and available drawings or photos.

Can you replace an old oil and gas control panel?

Yes. For replacement projects, send old panel photos, PLC/RTU model, wiring drawings if available, field device list, voltage information, and shutdown logic notes. We can review the information and propose a practical replacement configuration.
