Abstract
The present invention relates to a system, apparatus, and method provided to selectively produce petroleum fluid from multiple production zones well. The apparatus comprises a casing running downwardly into the well and a tubing string running in the casing. The upper and lower sealing mechanisms are provided for sealing the annular space between the casing and the tubing string, therefore, dividing the well into upper and lower production zones. Moreover, the invention comprises a bypass gaslift system provided with a tubular member, tubing string, connecting means and side pocket mandrels for injecting lifting gas into the multiple production zones well. The system and apparatus according to this invention can selectively operate to simultaneously or separately produce petroleum fluid from vertical apart multiple zones well.
