CS-HTH/NTN PERMANENT PACKER

INTRODUCTION

CS-HTH and CS-NTN hydraulic-set packer is single-trip permanent millable production packer. It is ideal for highly deviated and/or single-trip production and injection applications.  This packer includes a one-piece mandrel and seal bore, which eliminates a potential leak path. It has  a low profile for greater running clearance to help reduce problems that may occur when running  in highly deviated and horizontal wells. Premium, metal-to-metal thread connections add to the  dependability of the packer. Ease of use has been proven in flanged-up, single-trip completions common in offshore operations.  This packer sets with low pressure, major components are rotationally locked, and materials are suitable for milling. No tubing manipulation is required to set the packer, and the hydraulic-set CSHTH packer is compatible with standard accessory equipment. An upper polished bore receptacle (PBR) or overshot tubing seal divider can be connected to the  top of the packer with either a seal anchor or Retch-Latch assembly. The upper PBR assembly can be  retrieved with either connection. The internal seal assembly is run in place and shear-pinned to allow space out and fluid displacement.
