Casing Plunger Systems

Swab-Rite Tool Corp.’s (SRTC) Natural Lift System patented Automatic Casing Plunger – a revolutionary method of capturing downhole pressure to unload liquids in gas wells, with no lift cost.

  • The plunger is designed to sit on bottom, waiting for fluid to build-up.
  • The hydrostatic forces trigger the plunger to close. Minimal bottom-hole pressure is then required to lift the plunger to surface.
  • Once the plunger unloads fluid it strikes the top of your well re-setting itself, falling to bottom and repeating the process.
  • Several types of sealing cups are available to combat most well conditions.
  • Reduce completion costs as no conventional tubing is required.
  • Replace Coiled Tubing/ Siphon Strings if critical velocity is too low.
  • No lifting costs.
  • SRTC patented Mechanical Casing Plunger – is available where customers want to control the plunger at surface. This type of plunger will perform similar to tubing plunger installations.
  • Full Service Solutions are provided from local machining to installation and maintenance.
