Challenge

Gas lifted, gas vented or wells with sustained annulus pressure pose a considerable risk to personnel and facilities. In these applications annulus gate valves and ring gaskets are the primary well barrier. Gate valves provide only a single barrier, which can be breached upon impact or collision.

 

Regulatory and/or company requirements may demand mitigation for the associated risks.

 

Solution

The MSASTM, provides an additional independent barrier in the wellhead VR profile. The MSASTM is hydraulically operated and connected to ESD.
