Brangus Oil Tools GW cup type packer is available in a full range of tubing or casing sizes, in Two-cup or Four-cup versions, 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.
Brangus Oil Tools 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.
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.
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.
There are five variations of GW packer cups; the Standard, the Standard Heavy-Duty, the GWD Heavy-Duty, the Special and the Special Heavy-Duty. Each is available in a wide range of sizes. These cups, plus the two type of GW packers, give the operator virtually unlimited possible combinations from which to choose for the well service purpose.
