Plunger Lift Downhole Equipment

Engineered tools for reliable, energy-efficient well deliquification

Plunger lift

Liquid loading reduces gas flow, increases downtime, and shortens the economic life of your wells. SLB downhole plunger lift equipment provides a proven, low-energy method to lift accumulated liquids using only the well’s natural pressure. Through advanced metallurgy, precision manufacturing, and validated designs, these tools help maintain stable production across diverse well conditions.

  • Mature gas wells experiencing liquid loading — restore flow rates using natural reservoir energy.
  • Low-pressure or marginal wells — achieve deliquification without high operating costs.
  • High-sand or high-debris environments — maintain reliable operation with engineered plunger families.
  • Wells requiring rapid cycle times — improve lift efficiency with low-friction tool designs.
  • Operations prioritizing safety and equipment longevity — reduce impact loads and equipment fatigue.

Engineered plunger families for all well conditions

SLB offers a full portfolio of plungers designed to match well pressures, sand production, cycle rates, and tubing configurations, including:

  • Pad plungers for moderate debris and consistent lifting.
  • Brush plungers for debris-laden wells requiring cleaning functionality.
  • Sand plungers for high-sand environments.
  • Solid plungers for high-efficiency lifting and long life.
  • Shock absorber plungers to reduce impact loads.
  • Flow-Thru plunge designs for bypassed fluid during descent.
  • Liquid aeration plungers to reduce fall time in high-liquid wells.
  • PCS Ferguson First Responder two-piece fast-fall plunger

Bottomhole bumper springs engineered for reliability


  • Collar-stop designs for wells requiring fully contained motion control.
  • Collet latch springs suitable for standard fishing necks.
  • Standing-valve combos that simplify retrieval and reduce installation complexity.
  • Tubing-stop combo springs for wells with variable seating depths.

Forged surface components designed for safety and durability

Using forged 4130 steel with consistent grain structure, SLB-supplied forged lubricator bodies provide improved impact resistance and durability (hydrostatically tested to 7,500 psi per lubricator sheet).

  • Dual ½-in NPT outlets
  • API 6A-compliant
  • Rated –50 degC to 82 degC

Additional downhole equipment


  • Tubing stops: The tubing stop sets a stopping point for the tubing string without the use of couplings to set the collar stops
  • Auto-dump pack off tool: The auto dump pack off tool is used in wells with a tubing stop to pack off tubing to hold fluid

FAQs

How do I choose the right plunger for my well?

Selection depends on pressure, cycle time, sand content, and tubing size. The plunger families above are designed to match specific operational environments.

What equipment helps prevent plunger damage?

Forged lubricators with Poly-Spring technology improve impact absorption and reduce fatigue, per validated design data .

How does plunger lift reduce opex?

It relies on the well’s natural energy—no motors or compressors required—significantly lowering operating cost.
