GW Cup-Type Packers and Cups Tubing and Casing Cup-Type

The GW packer is available in a full range of tubing or casing sizes, in two-cup or four-cup models, with either standard or special cups. In its simplest form, the two cup GW has a one-piece seamless steel mandrel with top and bottom box connections. It has no latch or locking mechanism to be fouled by sand, shale, or mud. It has no slips, does not require tubing weight to be set, and packs-off equally well at any point in the hole.

The GW packer is offered in two types: Standard and Special. Simplicity of design, rugged construction, and unusually low cost make the GW attractive to the operator for a wide variety of applications.

Standard GW Packer

The Standard GW packer has a seamless steel mandrel with an extra large opening. Standard GW, Standard Heavy-Duty GW and GWD Heavy-Duty cups fit this packer. The Standard GW packer is suitable for all applications involving normal pressures.

Special GW Packer

The Special GW Packer has a full-opening, thick wall, seamless steel mandrel, making it an excellent choice for rugged-duty, high-pressure applications. The Special GW and Special Heavy-Duty GW cups fit this packer.

Powerful Type GW Packer Cups

The GW cups, used as a packing element on this packer, hold so well that the operator is cautioned to be sure means of bypassing fluid is provided when using the GW packer. Where fluid circulation above the cups is required, a Guiberson circulation slide valve may be used. For anchoring the packer, a Guiberson mechanical tubing anchor or a Guiberson hydraulic anchor is recommended.
