Oil & Gas Equipment Solution

FST’s customizable, space-efficient packages can be mounted with all of your upstream assets, from spools and trunklines to motors and control systems, complete with remote monitoring and solar power.

Modular Wellsite Package (MWP) is an integrated skid-based unit containing all wellsite equipment and components required between the X-mas tree and the main flow line leading to the gathering station. It includes HIPS, CIS skids, Wellhead Shutdown Panels, Sampling Units, Cellar ventilation arrangement, Fire & Gas Control System, PLC Systems ,Communication Systems etc. All these equipment which comes in between X-mas tree and header line are neatly arranged within the modular package making it a compact design which can be mounted on pre-designed foundation. The complete package can be fully integrated and tested as one unit. MWP units can be built for gas, oil and as well as injection wells.

For wellheads that require high reliability and programmable logic control, FST has developed the PLC-based wellhead control system. The system is designed with advanced fault-tolerant, fail-safe programmable logic controllers, internationally certified safety I/O modules, simplex/redundant configurations, and communication modules for intelligent control of the wellhead.

Power sources: manual hydraulic pumps and electric hydraulic pumps.

Control objects: surface safety valves and subsurface safety valves.

Applicable working conditions: wellheads that require high reliability and programmable logic control.

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.

Designed for oil/natural gas wells with special working conditions such as high temperature, high pressure, and hydrogen sulfide-enriched.

The high-pressure and hydrogen sulfide-enriched wellhead safety control system mainly adopts pneumatic-hydraulic or electric-hydraulic type, and the communication and safety control system is integrated with RTU and SCADA, which can easily achieve local and remote control. This type of wellhead control panel is suitable for service environments containing H₂S and CO₂. The valves, fittings, and tubings are selected according to the characteristics of media.

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/natural gas wells with special working conditions such as high temperature, high pressure, and sour gas.

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.

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.
