PTC’s VR Sense RTM systems are unique annulus monitoring solutions delivering independent double barrier integrity at wellhead side outlets. They are also retrievable under pressure. Their use eliminates the need for gate valves and instrument flanges. Consequently, they are a cost effective and higher-performing alternative. The product family has an excellent track record since its introduction in 2012.



Wells with sustained annulus pressure pose a considerable risk to personnel and facilities. Continuous monitoring of this pressure is critical for safe operations.

Conventional monitoring systems often contain a gauge downstream gate valves/flanges.


Gate valves provide only a single barrier. Impact or collision can breach this barrier. Blockage by valve lubricant can impair pressure gauge operation. Regulatory and/or company requirements may demand continuous monitoring and alarms.



The VR SenseTM system, provides continuous monitoring, even during ESD shut downs. The VR Sensor is designed with two independent metal-to-metal barriers. Should an impact or collision take place, the API 6FD/FB fire tested gas tight VR sensor plug will remain within the wellhead. The two internal barrier plugs are retrievable and replacable under pressure (live annuli).


The VR sensor removes potential issues related to viscous valve lubricant and can substantially lower installation and maintenance costs.


The system also eliminates the need for human intervention in conjunction with gauge calibration, gate valve operation and maintenance.
