PosiTest Retrievable Packer

The PosiTest retrievable compression packer is a fullbore, cased-hole, retrievable compression-set packer with a large internal bypass. The packer is designed to withstand high flow rates, elevated temperatures, and high pressures when the appropriate amount of weight is applied to the packer. The sealing elements effectively isolate annulus fluids from the perforated interval.

Long-stroke packer

The PosiTest long-stroke packer is similar to the standard PosiTest retrievable compression packer except that it is set by string reciprocation instead of string rotation. The long-stroke packer can be easily redressed between operations or converted quickly to run in another casing weight.

Hydraulic hold-down

The hydraulic hold-down complements both the standard PosiTest packer and its long-stroke version. It prevents upward movement as a result of hydraulic forces acting below the packer during stimulation or when a firing head is being activated. This combination functions similarly to the PosiTrieve packer with hold-down section; all hydraulic hold-down modules can be used with the long-stroke PosiTest packer.
