Abstract:
A flow control system includes a pump positioned in a wellbore to remove liquid from the wellbore. An isolation device is positioned downhole of the pump and is expandable within the wellbore between a sealed position and an unsealed position. The isolation device in the sealed position substantially reduces gas flow at the pump during removal of the liquid.
