Zusammenfassung:Methods and systems are provided for controlling intermittent production of gas in association with liquids from a well. Production tubing disposed in the well provides a flow path for gas and liquids to the surface. An electrically-controlled choke and a controller are disposed at the surface. The choke is in fluid communication with the production tubing. The controller interfaces to the choke and executes autonomous control operations that control operation of the choke, wherein the autonomous control operations involve production cycles that include a production mode followed by a shut-in mode. In the production mode, the controller is configured to operate the choke in an open position. In the shut-in mode, the controller is configured to operate the choke in a closed position.
