The Product

The Hydraulic Surface Annulus Safety Valve

Wells with planned or unplanned sustained annulus pressure (SAP) pose a considerable risk to personnel and facilities. In these situations, annulus line gate valves (a gasket, bonnet seal or stem seal) are the primary well barrier envelope elements, with no back up in case of failure. Most O&G companies follow a double barrier well integrity management policy. In wells operated with SAP the single barrier gate valves are in breach of this policy. Annulus line gate valves also significantly increase the ‘footprint’ of the wellhead. They require regular testing, maintenance and occasional replacement, resulting in significant life cycle costs.

The Hydraulic Surface Annulus Safety (HSASTM) valve addresses all of the challenges listed above. It is installed in the wellhead VR profile, where (in wells with SAP) it becomes an independently testable element of the primary barrier envelope.

Technology

HSAS™ fail-safe close wellhead annulus barrier valve is the only integrity-valve that delivers independent double barrier intergrity. The HSAS™ mitigates the risk of uncontrolled release of annular content from leaks or accidents. The product family has an excellent track record since its introduction in 2008.

Features & Benfits

Hydraulically operated fail-safe close barrier valve
Unless hydraulic pressure is applied the valve seals in both directions
Easy pressure testing of the primary and secondary seal (and adjacent gate valve)
Annulus venting and moderate gas injection application
Retrofittable under pressure on wells with SAP
Designed and tested to API 6A, incl 6. 6FD/FB fine testing
NORSOK-D-010 compliant
Easy installation and service, even in live wells (less OPEX)
Interventionless and easy testing of the primary and secondary barrier elements
Eliminates the compromise to well management policy in wells with SAP
Eliminates the need for Gate Valve(s) and associated maintenance and testing (HSAS-R™)
No well bay piping modification required (HSAS-G™)
Reduces the annulus line valve footprint
No need to equalize before opening
In cases where the SAP is being bled off to the production flowline, the HSAS acts as a non-return valve
