Compression Unloader

The Compression Unloader is designed as a high-pressure accessory for compression set packers.  The Unloader is run above the packer pinned in the open or closed position.  After the packer is run to setting depth, the procedures required to set the packer will automatically close the unloader.  With the packer set and the unloader closed, well operations may proceed.

When run above a compression set packer, the Compression Unloader is opened to allow differential pressure to equalize before releasing the packer below.
