摘要

Many gas wells have liquid loading problems caused by oversized tubing, resulting in premature abandonment. This paper suggests that small tubing can be used in most any packerless sweet gas well, regardless of anticipated flowrate, without restricting production capacity. A method of flowrate control is recommended that insures that tubing flow stays at rates necessary to maintain mist flow, allowing all liquids to be produced up the tubing string. Excess volumes are produced up the casing/tubing annulus, where pressure drop due to friction is usually negligible. Maintaining mist flow up the tubing is accomplished by regulating the amount of gas allowed to exit through the annulus. This single loop rpocess is controlled using cost effective, simple, reliable, oilfield equipment.
