Isolation Valve Cleanup Subs

Remove debris above ball-type isolation valves

Reduce risks that debris will hinder valve operations

Clean up isolation valves with jetting or circulation subs to reduce the risk that debris will hinder or prevent valve operation. The jetting and circulation subs are designed for land or offshore applications, including in deep water.

The cleanup subs are designed to avoid damage to the isolation valve and packer bore. They are equipped with a standard washpipe box connection for installation on the end of the cleanup string. A range of sizes is available.

Schlumberger offers a jetting sub (left) and circulation sub (right) for clearing debris that may have accumulated above the sealing ball of an isolation valve.

MFIV-II

Mechanically controlled isolation valve

Isolate reservoir fluids within the lower completion and protect the formation from damage during remedial work and underbalanced perforating.

FIV-II

Formation isolation valve

Isolate reservoir fluids within the lower completion with this bidirectional barrier that helps prevent formation damage.

SFIV-II

Surface-controlled bidirectional isolation valve

Isolate reservoir fluids within the upper completion and maintain a barrier through multiple operating cycles.

AFIV

Annulus-controlled shrouded isolation valve

Use this isolation valve in selective multizone intelligent completions to separate production from the upper and lower zones.

FORTRESS

Premium isolation valve

Simplify transitions from the lower to the upper completion.
