ABSTRACT:
A programmable system for controlling the operation of a plunger completion oil or gas production well to optimize production from the well. The controller operates one or more motor valves controlling the well in accordance with programmable values of off-time, on-time and exhaust-time. The controller monitors whether or not a plunger arrival signal is received on each cycle of intermitting the well and changes either the off-time or the exhaust-time for the next cycle in response thereto. In oil well mode, the off-time is decreased slightly for each cycle following a cycle in which plunger arrival occurred and increased slightly for each cycle following one in which it did not. In gas well mode, the exhaust-time is increased slightly for each cycle following a cycle in which plunger arrival occurred before on-time expired and decreased slightly for each cycle following one in which it did not.
