SYSTEMS AND METHODS FOR DELIQUIFYING A COMMINGLED WELL USING NATURAL WELL PRESSURE

摘要

A method for removing fluids from a commingled wellcomprises positioning a fluid removal system in the well. In addition, themethod comprises sealing a first formation from a second formation,shut-ting in the annulus, and closing off an inner flow passage of a tubingstring. Further, the method comprises allowing the pressure of the first andsecond production zones to build up naturally. Still further, the methodcomprises flowing a fluid from the first production zone through a first of aplurality of check valves into the inner flow passage, and flowing a fluidfrom the second production zone through a second of the plurality of checkvalves into the inner flow passage. Moreover, the method comprisesre--opening the inner flow passage of the tubing string and lifting the fluidinthe inner flow passage to the surface.
