Abstract
A gas inflow control system is used in a well. A downhole tool is combined with an automatic valve that is automatically actuatable to a flow position in the presence of a well liquid flowing into the downhole tool. In the presence of gas flow into the valve, the valve automatically transitions toward or to a closed position.
