Gas recovery apparatus, method and cycle having a three chamber evacuation phase for improved natural gas production and down-hole liquid management

摘要

Natural gas produced from a well by executing a multiple-phase gas recovery cycle which includes a phase during which a relatively lower evacuation pressure is applied within the entire well bore to assist in accumulating liquids at a well bottom. The relatively lower evacuation pressure augments the national earth formation pressure to produce natural gas and liquid more rapidly. The phases of the gas recovery cycle are also coordinated with the phase in which the relatively lower evacuation pressure is applied throughout the well to facilitate a greater natural gas production rate.
