HYDRAULIC SET HIGH ANGLE ROTATIONAL RELEASE PRODUCTION PACKER


MODEL: WC-HPR-6

PRODUCT NO.: WC-25402


WC-HPR-6 is compact, economical, packer designed for low to medium-pressure applications. The short Body length makes it ideal for tight radius deviations and Horizontal applications. The packer requires no movement for setting, allowing stacked applications. Rotation releases the packer and built-in by pass ports equalize pressure across the packer for ease in retrieval. The shear Release mechanism is isolated from the packer hydraulics to allow Low release force even at full pressure differential.


Features

  • No mandrel movement for setting.
  • Low setting pressure.
  • Rotational Release
  • Shear screw isolated from hydraulic pressure.
  • Short in length.
  • Pressure differential rating 10,000 psi.
  • Tested in Q125 casing.

Benefits

  1. Low shear out force required, even at full pressure differential.
  2. Economical design makes packer easy to redr
  3. May be set with rig pump
  4. Stacked packer installations with sequential setting.

Applications 

  1. Offshore oil and gas application
  2. Highly deviated wells and severe dogleg
  3. Stacked-packer completion
  4. Coiled-tubing completions.

Setting Procedure 

Run in the hole to setting depth (Running speed should not exceed 90ft/min.) The Wellcare WC-HPR-6 packer is set by temporarily plugging the tubing string blow the packer and applying pressure inside the tubing. The tubing may be plugged dropping a ball to in the expandable seating sub run below the packer or by running a wire line plug to seat in a profile nipple or sliding sleeve run below the packer.

In installing where the Wellcare WC-HPR-6 is run in tandem, one temporary plug run below the

bottom packer is all that is required to set the packers. Pressurize the tubing will set all the packers simultaneously, or by adjusting the setting shear valve of each packer, the packers can be set individually. 


Releasing Procedure

Wellcare WC-HPR-6 packer is released by rotating the tubing string. Torque required to release the packer is

easily adjusted prior to running in.
