Our Flash Point™ packer is hydraulically set with a fully constrained running tool (HRC Running Tool) to allow rotation, resulting in greater control over liner installation and eliminating excessive work string manipulation during installation.

Capable of both conventional and thermal wellbore use, the Flash Point is fully functional up to 600 °F (315 °C). The Flash Point is tested and proven to maintain seal integrity at 600 °F (315 °C) with greater than 3,500 psi (24.1 MPa) of differential pressure across the element.


  • Hydraulic-set packer element
  • Hydraulic-release running tool
  • Dart operated with ball-drop backup for packer deployment
  • High-temperature design withstands up to 600 °F (315 °C)
  • Drains work string after packer has been set
  • Secondary mechanical release of running tool


  • High-temperature steam liner top isolation for injection or production wells
  • Allows for thermal temperature cycles along with ambient pressure test upon installation
  • Deployable on rotating liner systems for short-radius wells
  • Hydraulic setting tool ensures proper packer setting regardless of well depth or inclination
  • May be tied back with our seal nipple assembly


  • Steam-assisted gravity drainage (SAGD) injector and producer wells
  • Cyclic steam (huff-and-puff) wells
  • High-temperature oil production
