Paper: Effect of Back Pressure on Intermittent Gas Lift

Experience in the Jameson (Strawn Reef) Field has shown that back pressure imposed by inadequate flowlines, unnecessary valves and fittings and high trap pressures can be very detrimental to intermittent gas lift production and efficiency. As a result of minimizing back pressure, individual wells in this field have shown substantial improvements in production and injection gas-liquid ratios. Various methods of reducing back pressure are discussed, and a guide is presented to aid in selection of proper flowline sizes for intermittent gas lift wells.
