MODEL: WC-GCP   ,    PRODUCT NO.: WC-20914


The WELLCARE Model: WC-GCP Retrievable Casing Packer is a compact, economical set-down packer that can be used by itself for production applications or, with a companion un loader and hold-down, it can be used for well stimulation, testing and other pressuring operations and then left in the well as a production packer.


Features / Benefits

    • Short and Compact Even shorter and more compact than its predecessor, the Model “GCP” Retrievable Casing Packer offers true ease of storage, shipping and handling.
    • Permits Passage Of Recording Instruments - The bore through the Model WC-GCP Packer is full- opening for the size tubing on which it is designed to be run. Pressure bombs or temperature recording devices can be run through and below the tool if desired.
    • Low Cost - Economical to buy and economical to maintain, the Model WC-GCP Retrievable Casing Packer offers long and dependable service with minimum care and maintenance.
    • Alternate Packing Element System For temperatures up to 250° F, the standard 80 hard packing elements can be used with the Model WC-GCP Packer; for applications above this temperature, the packer is furnished with a 90 hard packing element.
    • Simple Construction - As is evident in the drawing on Page 2, the Model WC-GCP Packer is constructed of a minimum number of working parts. The dependable rocker-type slips and synthetic rubber packing element are the same types used on other highly successful Baker equipment.
    • Ease of Operation - A simple and reliable J- Slot mechanism, actuated from the surface, makes the Model WC-GCP Retrievable Casing Packer very easy to set and release.

Operation

The packer is run to a position about one foot below the desired setting depth, then picked up to the setting point. The tubing is rotated to the right 1/4 turn at the tool, and set-down weight (shown below) is applied to set and pack off the tool. To re- lease the packer, the tubing is simply picked up.

If the packer is to be moved down-hole and reset, the tubing is rotated to the left 1/4 turn at the tool.

The Model WC-GCP Packer also features a safety joint that permits removal of the tubing string if it should become necessary to do so.

The left-hand thread that connects the Top Sub to the Body will unscrew, permitting the removal of the tubing string and the Top Sub from the well.
