Abstract: A logic used to auto-adjust plunger lift system parameters to optimize oil and gas well production with minimal human interaction is described. The auto-adjustments place and maintain the well in an optimized state wherein the well has either a Minimum-OFF time (e.g., length of time just long enough for the plunger to reach the bottom of the well), or Minimum-ON time (e.g., flowing just long enough for the plunger to reach the surface) cycle.

Abstract: A method for determining when a plunger reaches the bottom of an oil or gas well equipped with a plunger lift system. More particularly, the method identifies a surface pressure associated with the plunger reaching the bottom.
