HYDRAULIC SET PRODUCTION PACKER, LARGE BORE


MODEL: WC-HP-1

PRODUCT No.: WC-20101


HP-1 is an industry standard, fully hydrostatic, hydraulic set and shear release single string retrievable packer. The packer is hydraulically activated by applying tubing pressure against a underneath plugging device. The packer requires only straight pull to release.

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


Features / Benefits

  • Operationally
  • Hydraulically activated, hydrostatic set-low pressure, rig pump capable activation.
  • Field adjustable shear
  • Built-in un-loader and bypass to aid in releasing and retriving
  • Pack-off is mechanically locked constantly reinforced by hydrostatic pressure
  • Triple seal multiple duro meter elements ensure pressure integrity over a wide range of temperatures and conform easily to casing
  • No mandrel movement during setting allows stacked packer
  • Hydraulic set for low hydrostatic head wells
  • Straight pull or optional rotational release
  • Hydraulic hold-down for differential pressure from below

 Application

  • Production, injection and zonal
  • Single string selective completions or dual string completions with multiple packers.
  • Deviated wells or other application where no rotation for installation or removal is
  • Application where displacing and setting after the well is flanged up is desirable.
  • 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 Pump- Out Plug or Ball Seat can 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 second 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.

Releasing procedure

The Packer is equipped with 30,000 lb shear ring for a straight up-strain release. Shear rings of distinctive shear values are available ranging from 20,000 lb to 50,000 lb for different sizes of packers.
