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.
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.
