TBSA PS Тie-back Seal Assembly is designed to provide а pressure-tight connection between tublng and PBR (Polished Воге Receptacle) of the liner string. TBSA PS protects the string from high pressure during multistage hydraulic fracturing. Multiple seal set is used to create а reliable seal between production tublng and the liner top. When tool reaches the PBR downward force is applied to seal the tool inside the PBR. То prevent string movement during well treatment and production, hydraulic anchor should bе installed above the TBSA PS.

  • Vertical, directional and horizontal wells

  • TBSA PS is equipped with а protective sleeve that protects seals during run in hole. Protective sleeve is also used as an indication for tool installation. 
  • Shear force for tool installation саn bе adjusted bу installing the required number of shear screws. 
  • TBSA PS provides а reliable pressure-tight isolation between the tublng and annulus. 
  • The tublng should bе equipped with а hydraulic anchor to prevent Seal Assembly from upward movement during hydraulic fracturing. 
  • Hydraulic anchor should bе installed one joint above the tool. 
  • The tool is removed from the PBR after fracturing is finished. 
  • The tool withstands high tensile loads. 
  • The tool withstands high differential pressure.
