Design and application of adaptive intelligent drainage and production process for high-water-production gas wells [PDF]
Youqicang pingjia yu kaifaHigh-water-production gas wells experience significant wellbore pressure loss. During production, pressure decline can cause the liquid droplets in the wellbore to fall back and accumulate, forming slug flow.
