摘要

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.
