Abstract: In a production system for producing oil or gas from multiple wells, the wells including at least a first well and a second well, each well using an artificial lift system that includes a plunger associated with a motor valve off time, and first and second identical connecting subsystems that connect their respective wells to a common sales line, the first connecting subsystem comprising: a. a plunger arrival sensor connected to a micro controller; b. a wellhead connected to the first well; c. a motor valve connected to the wellhead; d. first and second pressure transducers on either side of the motor valve, conductively coupled to the micro controller; and e. a micro controller for keeping the motor valve closed during the motor valve off time, and extending the motor valve off time following a determination of the existence of a pressure spike in the common sales line.
