WellBoss Millout extensions are used below a permanent packer when there is no retrieval function and the situation may be required where the packer will be milled. They are typically configured as PIN by PIN or BOX x BOX depending on the products required below the packer.

Millout extensions provide a larger ID below the packer providing a shoulder to anchor/catch a milling and retrieval tool during milling. They are often used as a means to protect dynamic seals in a seal bore packer type installation. Lengths are available to meet the customer requirement but 6ft is probably the most typical.
