Seal Bore packers

Double Bore Hydraulic Set Drillable Packer

DOUBLE BORE HYDRAULIC SET DRILLABLE PACKER

Double Bore Hydraulic Set Drillable Packers are hydraulically set versions of the CT-WDP Packer.

Model No.: CT-HDDP & CT-HDP

Product No.: CT-95403 & CT-95402

 CT-HDDP Model has an enlarged upper seal bore, which allows the maximum possible bore through the seal accessory which is latched into the packer.

These Hydraulic Production Packers incorporate maximum strength, uniformity of setting pressure, standardization of materials and a one piece body.

The range of bore sizes offered is such that accessories which are used for CT-WDDP series of Packers may be used with the CT-HDDP Packers.

The Large Bore Packers are available 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 large bore size.  The hydraulic setting mechanism makes Packers particularly suitable for use in highly deviated wells.

  • 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, thereby eliminating the problems of spacing out, landing etc.
  • The CT-HDDP Production Packer is run with Anchor Seal Nipples or CT-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 to 10, 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 packer.
  • Setting sequence of packer may be controlled to start at 1,500 psi.
