abstractNote = {Low volume gas wells can experience water accumulation in the tubing and well bore when the gas velocity and production rate are insufficient to lift fluids. Another problem that can occur in gas wells in older fields is the rapid buildup of salt in the tubing or casing at or above the perforations. Production ceases, requiring wireline cutting procedures and up to several days of deferred production. Equipment has been devised to solve these production operations problems by concentrically placing downhole a capillary tubing string made of type 316 or duplex stainless steel. The capillary tubing can be installed in lengths up to 18,000 ft. The capillary tubing allows the introduction of either foaming agents to lighten the fluid column or fresh water to dissolve salt deposits. In almost all cases, significant production increases have been observed and sustained with the introduction of foaming agents. Up to 75 b/d of water can be injected to dissolve salt deposits and maintain steady-state well production. This technique has significantly increased production from marginal wells with economic payout times of a few months or less. Elimination of salt plugging results in an immediate savings in well wireline costs.},
