Plunger Lift

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.

Explore our high-performance surface components, designed for safety, durability, and efficiency in plunger lift operations.

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.

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

Operates remotely via pneumatic signal

(Electric motor valve option available)

• Can be powered by an external air source for zero-emission operation
• Easily convertible between pressure-to-open and pressure-to-close

Optimize your plunger lift operations with our intelligent remote monitoring software. Designed to work seamlessly with plunger lift equipment, this system enhances operational efficiency through real-time data monitoring, intelligent control, and automated protection.

Features

The Intelligent Plunger Controller is a multifunctional gas well control device designed to optimize plunger lift operations. Paired with an intelligent plunger, it wirelessly receives real-time downhole data, then combines it with wellhead information to calculate the optimal plunger lift schedule. This system enables automatic optimization, ensuring stable gas well production, increasing gas output, and extending well life.
