This is a high-pressure, double-grip, retrievable packer that isolates the annulus from the production onduit in flanged wells, deviated wellbores, gas-lift installations, and other completions in which a mechanically set packer is unsuitable. The built-in zone-activated, pressure-balance system offsets pressure differentials across the packer, making it ideal for stacked-packer installations. The packer could be released by straight pick-up of the tubing string. It also features an upper slip releasing system that reduces the strain required to release the slips by dislocating a key non-directional slip first, which automatically releases the other slips.

Features/Benefits:

The straight-pull, shear-release pins are unaffected by differential pressure, enabling easy changes to the release force before running.

All components are locked to prevent pressure buildup or debris from presetting the packer, improving reliability when running the packer in the wellbore.

The pressure-balance system offsets pressure differentials across the packer, enabling the element to maintain an effective seal.

The double-grip system enables the packer to hold differential pressures securely from above and below, preventing packingelement movement and ensuring proper pack-off.

Applications:

Suitable for highly deviated wells and doglegs.

Onshore offshore completions, Stacked completions.

Water injection/Gas lift. Coiled-tubing completions.

This is fully hydraulic set retrievable large bore production packer, used for production, zone isolation, selective multiple-zone completions, stimulation etc.The packer features a mechanical, bidirectional slip system to anchor the packer and resist upward and downward tubing movement it also has a built-in internal bypass system that allows formation pressure to equalize before the slip is fully released. The packer is set by applying tubing pressure, which acts on the packer's setting piston area, shears the setting screws and activates the packer-setting mechanism. The setting-mechanism trigger pressure is adjusted by adding or removing easily accessible shear screws. The packer's hydrostatic chamber allows the packer to be successfully set at lower pump pressures. Once the packer is fully set, the pack-off force is mechanically locked into the slips and sealing element with a positive lock-ratchet mechanism. This allows the tubing to be landed in either compression or neutral condition. Packer release is accomplished by a simple upward pull on the tubing string.Unlike many hydrostatic packers, the packer can be adjusted or redressed in the field by onsite personnel. This packer also features an optional slick-lineintervention, selective-set feature with a choice of upward or downward shift.

Features/Benefits:

No Tubing Manipulation required: The setting mechanism of this Packer is activated with pump pressure. The Packer can be set after the well is flanged up and the tubing is displaced.

Setting Mechanism: The design of the setting mechanism ensures sustained pack-off force throughout life of the Packer. Setting activation pressure can be adjusted by dressing up with required number of Shear Screws.

Opposed: Double grip slips prevent movement of the Packer in either direction due to pressure differentials.

Unloaded valve: Built-in equalizing and circulation system ensures increased safety and easy retrieval.

Multiple: Packing element system Design is compact and field proven.

Quick and reliable installation in highly deviated wells.

Test the tubing string before packer setting or to independently set and test individual packer in multiple packer completion

Setting Procedure:

The packer is set by pressuring the tubing to obtain a differential at the packer. To accomplish this temporary plugging device below the packer must be provided. Run a Hydro-Trip Pressure Sub, below the Packer or a Flow Control Seating Nipple installed at some point below the packer, with a Blanking Plug run and retrieved by standard wire-line techniques. Wireline Re-Entry Guide with PumpOut Plug or Ball Seat also be used to blank off tubing. If more than one Packer is to be run, place the tubing plugging device below the lowest packer. When the tubing is pressured in this case, all of the hydrostatic packers will be set simultaneously. If it is desirable to individually set and test each packer, the packer is adaptable to individual setting and testing by a simple adjustment of shear screws in the segment retainer housing. Dress the lowest packer with two brass shear screws. When dressing packers for this type hook-up, should be dressed with shear screws of same shear values. Dress the second (middle packer in three-packer hookups, or upper in two-packer hookups) with five brass shear screws, and a third (upper) packer with eight brass shear screws.This allows the packer to be set individually. The first will set at 1, 000 psi, the at 2, 000 psi and the third at 3, 000 psi differential pressure. In order to test the packers individually, a means of temporary communication between the tubing and the casing (i.e. a Sliding Sleeve below each packer) will be necessary. The lower packer can be set and tested down the casing. The second packer can then be set, the sleeve below it opened, and the second packer tested down the casing. The third packer is set and tested the same way. It is recommended that a blanking plug be used to temporarily plug the tubing for setting the packers because of the higher setting pressures.
