MODEL: WC-HSDDP

PRODUCT No.: WC-26101-15K


The Model WC-HSDDP Hydraulic Set Double Bore Drillable Packers are hydraulically set versions of the WC-WSSDP Packer. WC-HSDDP Model has an enlarged upper seal bore, which permits the maximum possible bore through the seal accessory which is latched into the packer. These Packers incorporate maximum strength, uniformity of setting pressure, standardization of materials and a one-piece body.
The Large Bore Packers are made in sizes which enables them to use the range of accessories which is available for drillable series of Packers. They have a lower pressure rating because of the increased bore size.  The hydraulic setting mechanism makes Packers particularly suitable for use in highly deviated wells. Careful choice of materials for components, which are exposed to the well fluids, enables the packers to be used in a wide range of operating conditions    


Features / Benefits

  •  Solid, slim lined construction and a packing element system which resists swab-off. This permits a fast run-in (when compared with earlier models of permanent packers) without fear of impact damage or premature setting, yet packs off securely and permanently when the packer is set.
  • Two opposed sets of full circle; full strength slips ensure that the packer will stay where it is set.
  • Interlocked expandable metal back-up rings contact the casing and create a positive barrier to packing element extrusion.
  • Setting requires no rotation or reciprocation, there by eliminating the problems of spacing out, landing etc.
  • The WC-HSDDP Packer is run with Anchor Seal Nipples or WC-STNE-1 Setting Tool Nipple.
  • All O-Rings which separate casing and annulus pressures are supported by back-up rings to improve long term seal integrity.
  • All Packers are designed to withstand pressure differentials up to15, 000 psi.
  • Guide furnished as standard, allowing the attachment of a mill out extension or other equipment below the packer.
  • All alloy materials within the packer are suitable for H2S service.
  • Can be furnished with Kalrez O-Rings for severely corrosive environments.
  • Body & Guide (components in flow paths) can be furnished in customer’s choice of material.
  • Fluid displacement is possible after well is flanged up and prior to setting the packe
  • Setting sequence of packer may be controlled to start at 1,500 psi

Operating Procedures Running In And Setting:

The Models WC-HSDDP-15K has an enlarged upper seal bore and a Left-hand Square thread in the upper end of the packer’s body. Anchor Tubing Seal Assembly will latch into the upper end of the Packer body to attach the Packer to the tubing string, and give a uniform, smooth bore through the packer and anchor. Any tail pipe assembly is attached to the lower end of the packer. A plugging device must be positioned below the packer, so that tubing pressure can be applied to set the packer.
Suitable plugging devices are:
a) Shear-out Ball Seat Sub
b) Hydro-Trip Pressure Sub
c) A wire line blanking plug seated in a suitable Landing nipple.
Run the packer to depth, and drop in the tripping ball or run the wire line plug as appropriate and apply the setting pressure to the packer. Hold the pressure for ten minutes and either pump out the tripping ball or retrieve the wire line plug.
