Plunger lift technical details
Design features
Plunger lift is a widely used artificial lift method, ideal for low-volume, high gas-liquid ratio (GLR) wells. This technique harnesses the well's own energy to lift accumulated fluid from the tubing to the surface, effectively utilizing the gas stored in the annulus. The plunger creates a mechanical seal that prevents gas slippage and liquid fallback, ensuring reliable fluid extraction.
Our ULT Plunger Lift System integrates the latest sensor technologies, significantly improving measurement accuracy. Combined with the ULT intelligent controller, which features AI-powered control modes, the system has been field-proven to optimize production, maximize efficiency, and extend the life of your well.
Surface components
Explore our high-performance surface components, designed for safety, durability, and efficiency in plunger lift operations.
Lubricator
The lubricator is the primary surface unit in a plunger lift system. It acts as the landing point for the plunger when it reaches the surface, protecting the system and enabling controlled operations. Key components include a shock spring to absorb high-velocity impacts, a plunger catcher mechanism, and flow ports.
Key Features

Motor Valve
The motor valve is a critical flow control component in plunger lift systems. Acting as a shutoff valve, it manages gas and liquid flow by opening and closing at precise intervals, coordinated by the system controller. This timing allows the plunger to rise and fall, efficiently clearing liquids from the tubing.
Key Features

Plunger lift FAQ
How does a plunger lift system work?
The motor valve shuts the well in so pressure builds while the plunger falls to the bumper spring at the bottom of the tubing. When the valve opens, gas stored in the annulus drives the plunger and the liquid above it up to the lubricator. The plunger seals between gas and liquid, so gas does not slip past and liquid does not fall back.
Which wells suit plunger lift?
Plunger lift suits low-volume gas and oil wells with a high gas-liquid ratio (GLR), especially gas wells that load up with liquid. It also helps prevent paraffin and scale build-up. For higher liquid rates or sandy, deviated wells, look at the jet pump or a beam pumping unit.
What is an intelligent (smart) plunger?
An intelligent plunger carries sensors that log temperature, pressure and acceleration on every trip. At each arrival it hands its data to the wellhead receiver, and the controller uses it to work out liquid column height and set the open and shut-in times for the next cycle.
Which plunger type do I need?
Solid (spiral) plungers suit low to moderate gas volumes. Padded plungers seal tighter to cut liquid fallback. Continuous flow (bypass) plungers suit high-velocity gas wells of 10+ ft/s with minimal shut-in. Brush plungers handle sand, salt or coal fines. Send us your well data and we will recommend one.
Does plunger lift need a rig to install?
No. The system installs without a rig, and the plunger is the only moving part. The controller runs on a 50 W solar panel and battery, with 7 days of standby without sunlight (14 days optional).
What sizes and pressure ratings are available?
Plungers, hold-down tools and lubricators come in 2-3/8, 2-7/8, 3-1/2 and 4 in. Lubricators have a 3,000 psi standard working pressure and are hydrotested to 5,000 psi, with sour service configurations available.
