The “AD-1” is a tension set, retrievable packer

· Shear ring secondary release

· Right-hand safety joint emergency release

· Rocker type slips

· Inexpensive

· Parts interchangeable with other manufacturers

Setting Procedure

Run the packer to desired setting depth, making the last movement downward. Rotate the tubing to the left one-quarter turn at the tool. Pick-up tubing to apply desired tension and maintain pack-off.

Releasing Procedure

Lower the tubing at least one foot more than is needed to remove applied tension so that the j-pin will move fully to the top of the j-slot.

Rotate the tubing to the right one-quarter turn at the packer so slips will now be in the running position. Packer can be moved to a new position and reset or it can be retrieved.

As an alternate release method, the AD-1 Tension Packer has shear rings designed to part at tension varying from 13,000-100,000 lbs. The cone, packing element and guide drop down and are carried out of the hole by the bottom sub.

If normal release is not possible, left-hand square threads on the top sub of the packer allow the tubing to be retrieved when the packer will not otherwise release.
