Abstract
A method and apparatus for operating a plunger lift system in a well can include: opening a control valve and allowing a plunger to rise to a top of the well; determining an actual rise time of the plunger based on a time it takes the plunger to rise to the top of the well; using actual rise time of the plunger and a target rise time calculating adjustments to the afterflow time or close time; and allowing the afterflow time to pass before closing the control valve and keeping the valve closed for the close time. The methods are repeated, each time calculating a new adjusted afterflow time or adjusted close time to incrementally alter these times.
