Bottom Hole Springs

Bottom Hole Bumper Springs protect the plunger and downhole tubing equipment from damage by absorbing the impact of the plunger when there are limited or no liquids in the well to cushion its fall.

  • Collar Stop Bumper Spring. Installed inside the tubing string in tubing that is “collared,” the Collar Stop is set in the collar gap between the ends of two pieces of tubing via wireline. Permanently attached, the spring cannot travel up behind the plunger.
  • Collet Latch Bumper Spring. The collet latch can be latched to any standard fishing neck. It is normally used when a “special” stop is required or a down hole device is already in the well.
  • Standing Valve Combo Bumper Spring. By combining the spring and the standing valve, this combo is easier, quicker, and less expensive to install and retrieve. It may be used as a standing valve (with ball and seat added) or the standing valve cage (without ball and seat) may be used as a convenient hold down.
  • Tubing Stop Combo Bumper Spring. Installed inside the tubing, via wireline, when no seating nipple is available. The single assembly is easier, faster and less expensive to install than the two pieces separately.
