The WS Model WS-HPL-4 Retrievable Packer is hydraulic set, large bore double grip Packer, used for Production, zone isolation, multiple string completions and for stimulation.
The Setting starts on application of pump pressure to the tubing. The “WS-HPL-4” sets and packs off due to the force applied by tubing pressures. The design of the setting mechanism ensures sustained pack-off force throughout the life of the Packer. Opposed Double Grip slips prevent movement of the Packer in either direction due to pressure differentials, while allowing landing of the tubing in tension, compression, or neutral.

The standard model “WS-HPL-4” Packer is equipped with Shear Screws for a straight pickup release. The Packer is suitable for maximum 5,000 psi differential pressure.

Features And Benefits

• Large Flow Path ID: 2.441” ID for 5 1/2” Size.
• No Tubing movement for packer setting allows well to be kept positively controlled at all the times.
• Two or more packers to be set together in any desired sequence.
• Bi-Directional slips to arrest upward & downward movement.
• High performance triple seal multidurometer element package.
• Straight pull release.
• No Premature setting of packer, blocked by an integral lock nut.

The WS  Model WS-HP-1 is an industry standard, hydrostatic set, Double-Grip and shear release single string retrievable packer. The packer is hydraulically activated by applying tubing pressure against underneath plugging device. The packer requires straight pull or rotation to release.

WS-HPL-1 is the large bore version of the WS-HP-1 packer. Features, advantages and operational procedures are the same as those for PGOT-HP-1 packer.

Features And Benefits

• No Tubing Manipulation Required. The setting mechanism of this packer is triggered with pump pressure. The packer can be set after the well is flanged up and the tubing is displaced.
• Hydraulic Set for Low Hydrostatic Head Wells. The.’PGOT-HP1″ Hydrostatic Packer can be set by tubing pressure alone at any depth. However hydrostatic pressure also helps in setting the packer
• Setting Mechanism. The design of the setting Mechanism ensures sustained pack-off force throughout the life of the packer. This tool does not depend on trapped hydraulic pressure, but mechanically locks initial setting forces into the Packing Elements. Any additional bottom hole pressure Or mechanical load due to tubing expansion is transmitted as additional pack-off force Reduction of bottom hole pressure or tubing contraction, however, does not diminish the initial setting force.
• Multiple Packing Element System.
• Hydraulic Hold-Down. The Pistons of the Hydraulic Hold-Down are protected against dulling while running in the hole by Restraining Pins installed inside the Piston Springs. After the tool is set, the Restraining Pins shear, allowing the Pistons to bite into the casing before pressure differential from below is sufficient to move the packer.
• No Mandrel Movement after Setting. AII downward movement of the Receptacle with respect of the tubing, and all upward movement at the tubing with respect to the Receptacle during setting are trapped in the Body Lock Ring. Once set, the packer will withstand slack off or up strain (within the limits of the shear value selected).
  AII slack-off goes into the  Packing Elements, whereas all up strain goes through the Shear Ring (or Shear Nut) to the Slip

  Ring and Slips to the casing.

• Optional Rotational Release. An optional right-hand rotational release with a safety shear value of 50,000 lbs.

Applications

This packer can be used in the following applications: production, injection, and zonal isolation; single-string selective completions or dual-string completions with multiple packers; deviated wells or other applications when rotation for installation or removal is not beneficial; when it is beneficial to displace and set packers after the well is flanged up; when testing the tubing string before packer setting or to independently set and test individual packers in multiple-packer completions is beneficial.

The WS Model WS-HP-2 Isolation Packer is a hydraulic set, single string tandem packer used in multiple zone wells. It is used as the upper packer in multiple zone applications.

The field-proven isolation packer can also isolate casing holes or perforations. The simple design and straight tubing-pull release make the packer a cost-effective tool to isolate zones in low-pressure applications.

Features And Benefits

• Economical Design

• Stacked applications.
• Applications prohibiting tubing rotation.
• Isolation of casing holes and perforations.

The WS Model WS-MECH-1 & WS-MECH-2 are retrievable set-down packers designed for use in various oil and gas well operations. These packers feature a large bypass area, controlled by a face-seal bypass valve actuated by a 30-inch stroke mandrel.

The packers are available in two configurations: a single-grip version, ideal for conventional long-stroke production, and a double-grip version with a hold-down mechanism, designed for both production and stimulation operations.
