Pressure balanced BOP well isolation Ram valve designed for superior reliability & performance

Deployed as:

• Open Water Lubricator Valve [OWLV]

The Entervene Open Water Lubricator Valve is single piston mounted on a vertical axis to the well bore and the predetermined piston to ram travel relationship provides maximum force in the cutting/close stroke. The Entervene OWLV is equipped with verification lines for guaranteed retraction and a secondary system activated in the event of losing hydraulic control makes it an innovative piece of engineering.

Features

• Cutting capability from 0.108” slickline up to 2 7/8” coiled tubing with a 0.204’’ wall thickness 90 KSI coiled tubing c/w 7/16’’ logging cable
• Should surface hydraulic control be lost, the secondary system can be activated to retain both upper and lower valves in the open position.
• Chemical injection facility below the rams via a dual protected NRV.
• Open verification lines to verify piston has fully retracted to the open position.
• The valve provides protection against dropped objects to the upper surface of the ram bodies. Impacts up to 35KJ have no effect on the operational or sealing reliability.
• Bi-directional sealing
• The Entervene OWLV is a fully pressure balanced system enabling a Fail-as-is (FAI) operating mode.(Traditional BOP fails open)
• Actuation mechanism in the Entervene OWLV ram design comprises a single piston mounted on a vertical axis to the bore well. (Traditional BOP operated via dual horizontally opposed pistons)
• Significantly reduced external envelope
• Negates requirement of complex ram lock system
• Piston to ram travel relationship predetermined to provide maximum force in the cutting/close stroke area
