“FH” Hydrostatic/Hydraulic Packer

The VORSI “FH” is a hydrostatic and/or Hydraulic set packer that allows the tubing to be left in a compression or neutral condition.

Applications include: multi-zone production in crooked or deviated holes not suitable for mechanical packers. Installations where the wellhead is flanged up before the packer is set.

Features

· No tubing manipulation required

· Withstands high hydrostatic pressures

· Hydraulic set for low hydrostatic head wells

· Locked in pack-off force

· No mandrel movement during setting

· Straight pull or optional rotational release

· Hydraulic hold-down for differential pressure from below

· Parts interchangeable with other manufacturers.

Setting Procedure

The VORSI “FH” Hydrostatic / Hydraulic Packer is set by pressuring the tubing to obtain a differential at the packer. To accomplish this a means of temporarily plugging the tubing below the packer must be provided.

Example: Run VORSI Tools Hydro-Trip Pressure Sub below the “FH” Hydrostatic / Hydraulic Packer or VORSI Tools Flow Control Seating Nipple installed at some point below the packer, with a blanking plug run and retrieved by standard wire line techniques. Wireline Entry Guide with Pump-Out Plug or Ball Seat can also be used to blank off tubing.

If more than one “FH” Hydrostatic / Hydraulic 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 t individually set and test each packer, VORSI Tools “FH” Hydrostatic / Hydraulic 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 tow bras shear screws. When dressing packers for this type hookup, all packers going on one string should be dressed with shear screws from one box to ensure similarity of 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 with approximately 1,000, the second 2,000 and the third 3,000 psi differential at the packer. In order to test the packers individually, a means of temporary communication between the tubing and the casing (i.e. a VORSI 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 standard VORSI “FH” Hydrostatic / Hydraulic Packer is equipped with 30,000 lbs. Shear ring for a straight upstrain release. Other values of shear rings are available (20,000 to 40,000 lbs for size 4-1/2 and 20,000 to 50,000 for all sizes 5-1/2 thru 9-5/8).
