Abstract
A method for producing oil or gas from multiple wells, the wells including at least a first well and a second well, with 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 includes: 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.
