Abstract: A casing differential pressure based control method used in conjunction with a gas-producing well includes the steps of sensing current sales line pressure and well casing and tubing pressures and changing or switching an A valve between open and close states based on differences between selected pairs of these current pressures relative to preset minimum differentials between the same pairs of these pressures. Open Differential Pressure determines when to open the A valve and initiate gas sales. Open Differential Pressure is the preset minimum pressure difference by which the casing pressure exceeds the sales line pressure. Close Pressure determines when to close the A valve and terminate gas sales. Close Pressure is the preset minimum pressure of the casing.
