MENU SIGN IN CONTACT Home Completions Well Completions Isolation Valves Downhole Isolation Barrier Valves Well barrier for isolating wellbore and reservoir fluids while minimizing risks CONTACT US RELATED DOCUMENTS Contain fluids during completion and workover operations Prevent formation damage and minimize workover costs with isolation valves that safeguard reservoirs by providing a reliable barrier within the completion string. Simultaneously minimize risks by isolating the formation and containing reservoir fluids, which increases efficiency by enabling batch drilling and completion operations. Suit your application with a wide range of options Choose the ideal isolation valves to suit your environments, including deepwater and subsea completion types, including single- or mutiple-zone completions and intelligent completions applications, including fluid loss control, gravel and frac packing, well suspensions, ESP workovers, underbalanced perforating, and downhole lubricator valves. 1996 INDUSTRY'S FIRST BARRIER VALVE >2,300 ISOLATION VALVES INSTALLED Trigger Mechanisms Interventionless Mechanical N2 S HP Control Line FORTRESS premium isolation valve Y Y Y Y FIV-II formation isolation valve Y Y MFIV-II mechanically controlled isolation valve Y AFIV annulus-controlled shrouded isolation valve Y Y SFIV-II surface-controlled bidirectional isolation valve Y TIVF flapper-seal tubing isolation valve Y Y Completion Types FIV-II Valve FORTRESS Valve MFIV-II Valve SFIV-II Valve AFIV Valve Intelligent completions • • • • • Stand-alone screens • • • • Gravel pack or frac pack • • • Multizone gravel pack or frac pack • • • Well suspension • • • • • Lubrication • • • • ESP workovers • • • Underbalanced perforating • • • • Multilaterals • • • The TIVF flapper-seal tubing isolation valve is used for tubing autofill, tubing pressure tests, and packer setting. API 19V and ISO 28781 Certifications ISO 28781 and API Spec 19V are international standards that prescribe the requirements for subsurface barrier valves and related equipment for use in the petroleum and natural gas industries. Subsurface barrier valves provide a means of isolating the formation or creating a barrier in the tubular to facilitate the performance of well operations before production or injection starts. Barrier valves are also available for the postproduction or postinjection phase. The standards define functional characteristics product material requirements quality control, defined by quality grades Q1 and Q2 design criteria design validation, defined by qualification levels V1, V2, and V3 design changes documentation requirements—operations manuals and product identification.

FIV-II Formation isolation valve Isolate reservoir fluids within the lower completion with this bidirectional barrier that helps prevent formation damage. AFIV Annulus-controlled shrouded isolation valve Use this isolation valve in selective multizone intelligent completions to separate production from the upper and lower zones. SFIV-II Surface-controlled bidirectional isolation valve Isolate reservoir fluids within the upper completion and maintain a barrier through multiple operating cycles. FORTRESS Premium isolation valve Simplify transitions from the lower to the upper completion. Isolation Valve Cleanup Subs Remove debris above ball-type isolation valves Clean up isolation valves with jetting or circulation subs to reduce the risk that debris will hinder valve operation. Primary Shifting Tool For the FORTRESS premium isolation valve Mechanically open and close the FORTRESS valve with this tool, run on washpipe, perforating string, or coiled tubing. TIVF Flapper-seal tubing isolation valve Eliminate interventions to open and close this valve for tubing filling, pressure tests, packer setting, and other applications.
