CS-HRA /HRB

HYDRAULIC-SET RETRIEVABLE PACKER

The Model CS-HRA/ HRB packer is the new standard for high performance single string retrievable hydraulic set, shear release packers. The CS-HRA offers features that provide maximum pre-set prevention while running, improved sealing and retrieving reliability, and metallurgy and elastomer selections fit for the well environment. The simple and reliable design is compliant. The selective setting mechanism prevents the packer from premature setting when high tubing to annulus pressure differentials is encountered or when tubing pressure tests are performed.

Features

  Ø   Production, injection and zonal isolation;

  Ø   Single string selective completions or dual string completions with multiple packers;

  Ø   Completions where maximum pre-set prevention while running is desired;

  Ø   Deviated wells or other applications where no rotation for installation or removal is desired;

  Ø   Applications where displacing and setting the packers after the well is flanged up is desirable;

  Ø   Stacked packer applications;

  Ø   Applications where it is desirable to test the tubing string before packer setting or to independently set and test individual packers in multiple packer completions.

Benefits:

  Ø   Hydraulically set and shear release, hydraulic interlock system prevents preset;

  Ø   Buit-in unloader and bypass -to aid in releasing and retrieving;

  Ø   Zero gap back-up system;

  Ø   Operationally simple, all O-rings tested during assembly of the packer,

  Ø   Bi-directional slip, and short, compact design;

  Ø   No mandrel movement during setting allows stacked packer applications.
