Detailed Description

The HS™ is setting the standard for high-performance, single-string retrievable, hydraulic-set shear-release packers. Its simple and reliable design provides maximum pre-set prevention while running and has improved sealing and retrieving reliability, metallurgy and elastomer selections it for the well environment. Other applications include: production, injection and zonal isolation; single-string selective completions or dual-string completions with multiple packers; completions that require pre-set prevention while running; deviated wells or other applications when rotation for installation or removal is not beneicial; when it is beneicial to displace and set packers after the well is langed up. The HS-S™ is beneicial when testing the tubing string before packer setting or to independently set and test individual packers in multiple-packer completions and stacked packer applications. The HS-S is the selective-set version of the HS hydraulic-set single-string packer. Setting and retrieval is the same as the HS with the exception of an inner sleeve that must be shifted mechanically before the packer will set. The selective-setting mechanism prevents the packer from premature setting when high tubing-to annulus pressure differences are encountered or when tubing- pressure tests are performed. Accessories A tubing-plugging device must be positioned below the packer for actuation: E™ hydraulic-trip sub (Product Family No. H79928); CMU(D)™ sliding sleeve (Product Family Nos. H81079 and H81080) with blanking plug; low-control seating nipple with blanking plug; hydraulic-setting devices (Product Family Nos. H46921, H79928 and H75917)
