FULLY HYDRAULIC SET LARGE BORE PRODUCTION PACKER


MODEL: WC-HPL-4

PRODUCT No.: WC-20103


Model: WC-HLP-4 Retrievable Packer is fully Hydraulic set 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-line- intervention, 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
  • 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
  • Unloaded valve: Built-in equalizing and circulation system ensures increased safety and easy
  • Multiple: Packing element system Design is compact and field
  • Quick and reliable installation in highly deviated wells
