Gas Lift - Fast and Furious
The Azeri-Chirag-Gunashli (ACG) field is a giant oil development located in the Azerbaijan Sector of the Caspian Sea, consists of several stacked reservoir layers being produced through 6 platforms (Chirag, West Chirag, East Azeri, Central Azeri, West Azeri, and Deep Water Gunashli) and being operated under a Production Sharing Agreement (PSA). The ACG field is becoming more mature in its development and the need for artificial lift is becoming essential to maintain production and enable the startup of weak wells. Gas Lift is the artificial lift mechanism currently selected for ACG and surface facilities are designed to support that method. The availability of high pressure gas for injection, and the high productivity potential of ACG wells were key factors in the selection process. Not all of the older ACG well stock is equipped with downhole gas lift mandrels (GLMs) today.
