Wells with planned or unplanned 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 Sensor 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.
