Abstract

A microprocessor-based controller for oil or gas wells using a plunger lift device is disclosed, which responds to variations in the well production and operation through a series of pressure input signals derived from the well operation. The controller will automatically make corrections in the operation cycles to maximize the well performance and maintain environmental safety.
