Description
The Wellhead Control Panel plays a critical role in ensuring safe operations for both onshore high-pressure/high-risk oil & gas wells and offshore platform wells, effectively preventing or reducing well incidents.
This system consists of hydraulic or pneumatic control circuits, equipped with pressure/temperature sensors and other monitoring devices to provide automatic fire protection, automatic well shutdown for production line overpressure/under pressure conditions, manual emergency shutdown (ESD) and remote emergency shutdown functions.

The WCP could shut down the well automatically under emergency conditions and be manually operated shutdown by manpower from buttons or ESD valve;
WCP could automatically close the hydraulic shutoff valves to shutdown the well if wellhead fire detection is triggered or pressure of wellhead pipelines are out of safety range (higher to lower);
WCP utilizes accumulators to provide power to stable inside pressure of system, and it also equipped with manual pump to repressurize the pressure distance.
Working Principle & Applications
The system is powered by a 380VAC, 50Hz electric pump, with hydraulic pilot control circuits, making it suitable for locations with available power supply. It is designed to control single-wellhead surface safety valves (SSVs) and subsurface safety valves (SSSVs).
Key Features
Equipped with wellhead fire protection function, featuring local ESD （Emergency Shutdown) protection capability.
Provides automatic well shutdown protection in case of abnormal pipeline pressure, if excessively high pressure, or excessively low pressure.
Supports remote ESD functionality, enabling emergency well shutdown protection via the central control room DCS system (including remote ESD, RTU remote monitoring, and control functions).
Key Features
Compared to electro-hydraulic systems, the pneumatic-hydraulic type system delivers higher control pressure up to 20,000 PSI.
Wellhead fire emergency shutdown (ESD) protection
Local ESD shutdown capability
Automatic well shutdown protection for abnormal production line pressure conditions including excessively high pressure or low pressure.
Working Principle & Applications
The system utilizes a pneumatic pump as the hydraulic supply, with compressed air serving as the pilot control circuit to control SSV and SSSV. The driving gas can be supplied from compressed air, nitrogen cylinders, or natural gas. The system is ESPecially fit for the well site in lack of electricity power or with high Ex-proof requirement.
Solar-powered operation reduces carbon emissions, offering energy usage efficiency and environmental protection.
Equipped with a charge controller that disconnects the battery from the charging circuit in case of under-voltage or over-voltage, while also cutting off the load circuit to protect the solar power system.
Provides emergency well shutdown (ESD) protection in case of wellhead fires.
Supports both local ESD and remote ESD shutdown functions.
Features automatic well shutdown in response to abnormal production line pressure, excessively high pressure, or critically low pressure.
Working Principle and Applications
Designed for centralized safety control of two or more wellheads, it adopts a modular design. Each module functions as a single-well control system, with one module assigned to each well. Maintenance, removal, or installation of any module should not affect the normal production of other wells. It is suitable for intensive onshore well sites, offshore platforms, artificial islands, and similar environments.
