Abstract
A flow control system includes a pump positioned in a well to remove liquid from the well. A check valve is positioned in the well and includes an open position and a closed position. The check valve in the open position allows gas from a producing formation of the well to flow past the check valve, while the check valve in the closed position substantially reduces gas flow at the pump from the producing formation. A compressed gas source is in fluid communication with the well to provide compressed gas to move the check valve to the closed position.
