WEFIC, a Kerui Petroleum’s wellhead brand, completed the API 17D subsea production system performance test of its MSW-1 shallow water mudline suspension wellhead system, filling the gap in China’s mudline suspension technology for underwater oil and gas production.
The test fully simulated the installation and pressure in the mudline environment.
In the test, 9 5/8″ and 20″ casing strings were able to bear 500 ton and 1,500 ton loads respectively, and operate under a pressure of up to 15,000 PSI, the company said.
The entire system can be deployed to complete drilling operations at a depth of approximately 150 meters, and tied back to the platform for well completion.
Huang Youliang, head of the project at Kerui Petroleum, explained that the MSW-1 shallow water mudline suspension wellhead system seals and suspends the casing strings at each layer in the mudline, controlling and transferring the pressure during underwater drilling.
