ABSTRACT:
An artificial lift deployed on concentric tubing allows gas to be vented from below packers in a well. A central flow path is used for the fluid production from the artificial lift system, while an outer concentric tubing allows for the venting and production of gas from below a packer. The gas enters the outer concentric flow path through a perforated sub set that is located below the packer. Sealing of the inner concentric string flow from the outer concentric flow path is achieved with a polished bore receptacle and stinger assembly.
