Gas-lift technology applied to dewatering of coalbed methane wells in the Black Warrior basin
1992
Coalbed methane (CBM) wells usually are dewatered with sucker rod or progressive cavity pumps to reduce wellbore water levels, although not without problems. This paper describes high-volume artificial-lift technology that incorporates specifically designed gas-lift methods to dewater Black Warrior CBM wells. Gas lift provides improved well maintenance and production optimization by the use of conventional wireline service methods
