CRM-ЗS Liner Hanger System with Hold-Down Slips is specially designed for cemented liner applications. CRM-ЗS is used to suspend the liner in previous casing using а liner hanger followed bу cementing operations. Work string is used to run in hole the liner to the desired setting depth without rotation. Running tool with mechanical release is then retrieved from the well once the liner is in place. 

  • Hydraulic activation of the Liner Hanger allows for using in deep, deviated wells without the need for drillstring manipulation. 
  • Hold-down slips above the packer sealing element allow to prevent the upward movement of the liner. 
  • Running Tool design with float nut allows release prior to cementing operations. 
  • Full-bore ID after running tool retrieve imposes по restrictions to liner access for future intervention and remedial operations. 
  • 10 ft Polished Воге Receptacle (PBR) allows to set the floating stinger without using а hydraulic anchor. 
  • Running tool at the bottom has а profile for Liner Wiper Plug. 
  • CRM-ЗS Liner Hanger System withstands high tensile loads. 
  • CRM-ЗS Liner Hanger System withstands high differential pressures.


  • Polished Bore Receptacle provides а mean of tying back into the liner with seal assembly for multistage hydraulic fracturing оr with second isolation packer. 
  • Liner Тор Packer provides high integrity annulus sealing. 
  • Hydraulic hanger provides specified holding force. 
  • Running Tool with а mechanical release. 
  • Liner Wiper Plug. 
  • Drill Pipe Dart Plug.
