Desert and Remote Wellhead Applications

For areas where power supply is unavailable in desert and remote regions, FST has developed a solar-powered wellhead safety control system that uses solar energy as a power source. For natural gas reservoirs, a gas wellhead safety control system can also be designed to use natural gas as a power source in order to reduce costs.

Considering the difficulty of inspecting wells in person in desert and remote areas, these types of wells are remotely controlled and monitored by RTU.


Power source: solar energy, electric hydraulic pump.

Control objects: subsurface safety valves, surface safety valves, etc.

Applicable working conditions: unmanned areas in remote areas such as deserts, Gobi, mountains, etc.

Surface Safety Valve

The Surface Safety Valve, together with the Wellhead Control Panel, forms the Wellhead Safety Control System.

Our Surface Safety Valve is a type of linear motion valve driven and controlled by pneumatic or hydraulic, and relied on spring reset. It is applied in oil and natural gas well fields to provide safety protection in critical situations such as oil and gas leakage or fire. It can directly and quickly shut off the wellhead.

Application on Offshore Oil and Gas Wellhead on Ocean Platform

Based on the characteristic of centralized control of multiple oil/gas wells on the ocean, FST has developed a multi-well wellhead safety control system, which contains multiple wellhead control modules. Each control module controls one well independently without interference, which facilitates maintenance and replacement.

The control system can be designed according to customer requirements as pneumatic-hydraulic, electric-pneumatic, electric-hydraulic systems with remote control interfaces.


Power source: manual hydraulic pump, electric hydraulic pump, pneumatic hydraulic pump.

Control objects: surface safety valve and subsurface safety valve, etc.

Applicable working conditions: oil and gas wellheads on offshore platforms.

Conventional chemical injection skid

This is used for conventional chemical injection in factories or oil fields, including chemical storage containers, pumps, valves and instruments, related tunbings, and electrical controls. All of these components are installed on a single enclosed skid. Conventional injection skids are widely used in onshore applications.

Multi-point chemical injection skid

The purpose of the multi-point chemical injection skid is to use a single metering pump to inject different chemical agents at different injection points, flow rates, and pressures.


This type of skid is more suitable for situations where there are a large number of injection points and limited space. This product replaces multiple chemical injection devices with a single skid, reducing operating and maintenance costs and improving space efficiency.

Gas Tightness Test bench

The gas tightness test bench uses high-pressure nitrogen to perform sealing tests on specimens, in order to meet the requirements of manufacturers and testing agencies for sealing tests on valves, wellhead Christmas trees, blowout preventers, and manifold.


For the gas tightness test of valves and wellhead Christmas trees, a multi-stage pneumatic booster pump is used for pressurization. The test meets the requirements of standard API Spec 6A and the specifications of PSL1-PSL4.

For the gas tightness test of blowout preventers and manifold, a hydraulic-driven booster pump is used, which has high efficiency and large displacement. The test meets the requirements of standard API 16A.
