  • Patent number: 5957199
    Abstract: A process for optimizing natural gas production from a well in the presence of liquids is provided where the well has a casing and a tubing landed therein for producing gas and removing the liquids. The process involves the steps of: opening the casing for gas production and closing the tubing to fluid flow; monitoring differential pressure between the open casing and the closed tubing; detecting a loaded well upon the differential pressure reaching a Well Differential Set Point value; switching gas production to the tubing by closing the casing and opening the tubing; monitoring pressures of the closed casing and the open tubing; removing liquids from the well through the tubing, during which time at least some gas production continues through the tubing during the liquid removal; and, returning gas production to the casing when the well is unloaded of liquid by repeating the above procedure.
