Our technologies encompass stand-alone innovative completion products that can be combined to form systems for use in conventional and unconventional wells.

SwellStack Sealing Systems

Swellable O-Rings and Sealing Systems

Tendeka’s oil and water swellable elastomers operate within a wide temperature range from 32°F (0°C) to 480°F (250°C), and are rated at up to 5,000 psi continuous working pressure.

SwellStack Seals and swellable O-rings provide pressure integrity in damaged safety valve sealbores, extending the operating life of the completion. 

Solving the challenges of delivering reliable sealing and isolation calls for an understanding of specialist fields such as multiphase fluid dynamics and materials science. Tendeka’s focus delivers large-scale and far-reaching benefits to your operations. 

Tendeka will work with you to design and engineer a sealing solution tailored to your requirements. Whether accommodating non-standard internal diameters or unique fluid parameters, the end result is a system that perfectly fits the needs of your project. 

Our expert materials scientists have developed proprietary elastomer technology to deliver reliable isolation performance across a variety of temperature and salinity profiles. After swelling, the element retains full flexibility and is able to react to subsequent changes in well bore geometry.

Features and Benefits

  • A cost-effective solution to extend the working life of existing DHSV
  • Simplify deployment reducing rig time and risk
  • Use existing control line fluid from rig system
  • Isolate reliably - even in severely damaged and corroded sealbores to provide long term well integrity
  • Less than 3000lbs to retrieve seal from a DHSV
