Advantages and Features:

Lower Height：

Ease of Operation and Maintenance –Due to its top can be reached by operator，no scaffolding operations are required. This will result in ease of site production, management, operation and maintenance.

Ease of Site Installation – Site installations are conducted on ground to improve greatly the efficiency of site installations.

Ease of Leakage Detected – Usually leakage arises from the valves and connections along production lines. For old wellheads of large overall sizes, leakages arising from production lines are difficult to find . But for compact wellheads, any leakages are at sight of operators and easy to find.

New Structural Design：

Ease of Work-over – Due to that production lines are below top flange, work-over operations can be conducted after opening top flange while thanks to no removal of production lines.

Cost Saving – With thanks to no removal of production lines for work-over operations, work-over operations can be conducted after opening top flange. Such configuration will bring down a great deal of time for usual removal of production lines, save tools, cut down cost of parts and materials replaced.


Saving of Site Installation and Maintenance Cost – Site installations will be finished on ground requiring no scaffoldings and tools. Only common portable tools and surface operations are required for maintenances of valves. A great deal of cost will be saved due to no requirements for large cranes on site.

Improving of Operation Efficiency:
Less Shut-down, High Work Efficiency – Ease of installations, production, daily management, operations, work-over and maintenances will improve work efficiency, minimize shut-down, cut down loss and improve incomings.

Compact Wellhead of Super Work Efficiency

In recent years more and more offshore platforms utilize such compact wellheads of super high efficiency for purposes of following features:

Lower Installation Height：

Ease of Site Operation and Maintenance
Ease of Site Installation
Ease of Leakage Detected

New Structural Design：

Ease of Work-over Operation

Cost Saving：

Save cost of work-over operations
Save time of site reinstallion and maintenance

Efficiency Improved：
Less Shut-down


The feature of distinguishing compact wellhead of super high efficiency from that of high efficiency lies in that the casing housing of super-high-efficiency wellhead also utilizes a compact structure to reduce the height for purpose of more ease of site operations.
