Abstract
A plunger lift management system may measure a casing pressure data series of an annular space between a casing and a tubing. A plunger lift management system may measure a tubing pressure data series of the tubing. A plunger lift management system may generate a pressure differential data series based on the casing pressure data series and the tubing pressure data series. A plunger lift management system may, based on the pressure differential data series, a weight of a plunger, and a length of the tubing, identifying a weight of liquid lifted by the plunger.
