The AD-1 Tension Packer is a compact, economical, retrievable packer. Primarily used in waterflood applications, this packer can also be used for production and/or treating operations. It is used where a set-down packer is impractical. Since the AD-1 is tension set, it is ideally suited for shallow wells where set-down weight is not available.

 FEATURES:

• Utilizes rugged rocker type slips
• Bore through the packer mandrel is larger than drift
• Simple, low cost packer for fluid injection
• Three release methods insure retrievability
• Uses proven one-piece packing element
• Alternative shear release

OPERATION:

Set:
Run packer to desired setting depth, making the last movement downward. Rotate the tubing to the left one-quarter turn at the tool. Then, pick up and pack-off

Release:
Lower the tubing at least one foot (0.30 m) 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. The packer can be moved to a new position and reset or it can be retrieved. As an alternate release method, this packer has shear rings designed to part at tensions ranging from 4,000 - 26,700 daN. The cone, packing element and guide drop down and are carried out of the hole by the bottom sub.
