A wellhead control panel (WHCP) is the main part of a safety system on a production platform or production location and are designed to provide safe and reliable operations in any environment. . The panels enable safe and reliable operation of the valves by providing hydraulic power and controls, and in some cases pneumatic controls. Wellhead control panel are also known as shutdown panels (SDP),  Emergency Shutdown Systems (ESD) and  Hydraulic Safety Shutdown System(HSSS).

Argus  Systems is one of the leading manufacturer of various types of wellhead control panel (WHCP) for the control and monitoring of   oil and gas production wells. wellhead control panel are vital elements in the main control and safety systems for onshore and offshore production facilities.

Wellhead Control Panels can be executed as a single wellhead, typically found in onshore locations, or a multi wellhead control panel, which are typically found in offshore locations. The main purpose of the wellhead control panel is to ensure controlled opening and closing of the Xmas tree valves in the event of an emergency shutdown or process shutdown.

Control of the wellhead control panels is often part of the plant control (ESD/PCS) system. However, for remote areas we provide standalone systems which include solar power, batteries, Telemetry and an E&I control pan.

A single well panel incorporates pneumatic and hydraulic valve controls for sequential valve operation(opening & closing ), emergency shutdown, manual override and safety shutdown. System pressure is generated by air driven or electrically driven pumps and displayed by means of gauges.

Our Systems are Designed, Manufactured, Installed and Commissioned according to customer specifications and are compliant with international and local regulations such as IECEx, ATEX, CE, CSA, UL, NR13, ASME, and PED.

Process Definition

A hydraulic supply reservoir is sized to provide sufficient storage for hydraulic control fluid. One or more pumps provide hydraulic pressure for each pressure section. Pumps can be electrically driven, pneumatically driven, or manually operated. Filters, monitoring and control instruments are installed downstream of the pumps. In order to maintain continuous operation and prevent the pumps from having to run continuously, a set of hydraulic accumulators is installed at the hydraulic headers. These accumulators are sized to open all of the valves.

In order to enable the operator to monitor the header pressure, the front panel of the unit will have pressure gauges and transmitters to provide for local pressure monitoring of the hydraulic headers. The hydraulic power section provides hydraulic power to operate the control section of the panel responsible for opening and closing the actuated valves. The well control section is designed to operate the hydraulically controlled Xmas tree valves.

The wellhead control panel automatically closes the valves in response to alarm conditions requiring shut-in. valves can be shut down manually or automatically, either from the front panel of the unit, or via the remote-control signal. Panels can include hydraulic or electrical logic, enabling the wells to be controlled by an ESD safety system, fusible plug loop or a high/low-pressure pilot valve. Sequential opening/closing operation of the valves is optional and can be fully automated, including an adjustable time-delay sequence setting. The wellhead control panel can monitor the status of the high/low process pressure in the flow line and automatically ensures shut-in of the well during emergency conditions.
