“AD-1” and “ADL-1” Tension Packers
The Model “AD-1” Tension Packer provides a compact, economical retrievable packer for use where
a setdown type packer is impractical because of pressure requirements. Although designed primarily
for waterflooding, this packer can also e used for such pressuring operations as formation fracturing in
shallow or low-fluid-level wells.
The Model “ADL-1” Tension Packer (Sizes 45 X 2.90 and 47 x 4.12) is a large bore version of the
“AD-1” Packer. Features and operational procedures are basically the same as those described for the
“AD-1” Tension Packer.
Features / Benefits

Short And Compact – Increases the efficiency of handling, shipping, and
storing, as well as operations on the rig.

Rocker-Type Slip Design – Eliminates the need for extra drag block, slip
tie links, and guide grooves, thus making possible not only shorter packers
but ones permanently free from stuck or cocked slips.

Easy To Operate – A simple and reliable J-Slot mechanism, actuated from
the surface by tubing rotation, makes the packer easy to set and release.

Packing Element System – For temperatures up to 250◦F, the standard 80
hard element can be used with sizes 41 through 51, and for applications
above 250◦F, a 90 shore element is available. The Size 53 and 55 tools
use a 70 shore element, rated to 225◦F, as standard and alternate
elements are also available for higher temperatures.

Full-Bore – Larger than tubing drift diameter. Any instruments capable of
passing thru the tubing can be run thru the packer. Full ID also assists in
preventing screen-out and subsequent plugging of the tubing during
fracturing.

Alternate Body with Larger ID – Body with 1.978 in ID (Size 43 only) is
available for use in areas where a pump is run, or where customer desires
to swab below the tool.

Operation
To Set Packer
Run the packer to desired setting depth, making the last movement down before attempting actual set.
Rotate the tubing to the left one-quarter turn at the tool, and pick-up on the tubing string to obtain packoff. Refer to chart below for upstrain required to set the various size packers.

To Release Packer
Lower the tubing string at least one (1) foot more than is necessary to remove the applied tension (this will move
the J-Pin to the top of the J-Slot) and rotate to the right sufficiently to obtain one-quarter turn at the packer.
Emergency Release
For use under extreme conditions, two safety release method s are available.
1.
These packers have an emergency Shear Ring installed on the Body, below the Guide, Application of
from 25,000 to 50,000 lbs tension (dependent on strength of Shear Ring) will shear the Shear Ring, permitting
the Cone, Packing Element and Guide to drop against the Bottom Sub where they will remain as the Packer is
retrieved from the well.
2.
If it is not desirable or practical to pull 50,000 lbs through the tubing, apply approximately 10,000 lbs
strain and rotate the tubing 20 or more turns to the right. This unscrews the left-hand safety thread between the
Top Sub and the Body and allows removal of the tubing string and the Top Sub. To remove the remaining
portion of the Packer, install a set of Jars made up above an overshot, socket or spear (or the Top Sub), engage
the Packer Body and actuate the Jars to free the Packer Body form the casing.

* Plain end: 12.24 – 14.98 lbs/ft
* Packer shown for this weight is recommended and should be run where possible; however, the other size
packer listed for this same weight may be run under certain circumstances, such as unusual hole conditions or
running mixed string.
NOTE: Repair Kits (including such items as packing elements, seal rings, etc.) are available.
Strain Required When Annulus Pressure Is Greater Than Tubing Pressure
Since the Tension Packers have only one set of Slips, which serve only a keep the Packer from moving up the
hole, special consideration must be given those operating conditions in which the annulus pressure will be
greater than tubing pressure.
When this situation exists, the Packer tends to pump down the hole with the result that it may come unpacked, or
under extreme conditions, the Shear Sub or Ring on the bottom of the Packer may be pumped off. Within
reasonable limits, how-ever, the annulus pressure may be greater than tubing pressure provided the downward
