HDR-HW

DESCRIPTION / APPLICATION
The HDR-HW Dual String Retrievable Packer is a high performance dual string hydraulic set, straight pull retrievable packer that requires no mandrel movement during setting and can be released on either or both strings simultaneously. The HDR-HW Dual String Retrievable Packer is utilised for both production and injection applications. The packer can be run as an upper packer where the bottom packer is a single-bore packer or as the upper or intermediate packer in tandem or selective-tandem dual completions.

FEATURES / BENEFITS
The design has two parallel pipes.
The construction has body bars squarely to the pipes to increase the capacity.
The fully symmetric construction ensures the interchangeability of the two strings and also ensures the changing of the way of the setting process too.
Field adjustable facility to set the packer through short string as well as long string.
There is a bi-directional fixing Slip-system below the Packing elements.
The bi-directional setting mechanism ensures that there is no down-acting pulling force on the pipes.
The full setting force has an effect on the packing elements.
The Packing Elements have a long-life because the bi- directional slips save that against the changeable mechanical forces.
The packing element system incorporates a back-up system which prevents elastomer extrusion
The construction of fixing of the Pipes ensures the independent rotation of the Pipes after the releasing.

The accessory of the HDR-H6 packer is the RK-2B locator type seal unit.
