Field evaluations of gas-lift and progressive-cavity pumps were conducted to determine their effectiveness as dewatering techniques for coalbed-methane wells in the Warrior Coal Field. AMPCO installed a gas-lift system in AMPCO Well No. 6. Problems included poor performance of all gas-lift valve designs and higher instantaneous water production rates than anticipated due to heading and unloading. The test provided the conclusion that gas lift is an effective start-up dewatering tool for initial removal of large amounts of water and solids but that in use as a long-term dewatering tool, needs additional evaluation relative to capital cost, valve design, and extended performance.
