摘要： An apparatus for a plunger lift mechanism with a main channel disposed between a first and second valve. The first valve is closed by engaging a sealing member to a first seat at a proximal end of the main channel and the second valve consequently closes to with a sealing member engaging a second seat at a distal end of the main channel. An amount of pressure accumulates on a first side of the plunger lift to overcome a pressure on a second side of the plunger lift to force the plunger lift to traverse a well bore and evacuate any fluids present above the plunger lift.

摘要： A controller and method of using same are disclosed. Preferably, the controller includes a pilot cartridge housing supporting an invertible pilot cartridge assembly (“cartridge”). The cartridge preferably includes a cartridge body supporting a number of pneumatic seals adjacent the housing, wherein at least two of the seals are diaphragms. The cartridge preferably provides a first pilot activation feature and an opposing second pilot activation feature. The operating mode of the cartridge is determined by a selected orientation of the first pilot activation feature relative to the housing; and preferably the method of operating the controller includes the steps of: selecting an orientation of the first pilot activation feature relative to the housing; setting a span control mechanism to a neutral position relative to the housing; adjusting a float communicating with the cartridge to a neutral position; and adjusting said span control mechanism to determine a response type of said cartridge.
