First test application was on a well in Hassi Messaoud field located in depleted zone. The well had a drastic WHP and Qoil drop within one year, as no potential downhole damage was identified artificial lift method was the recommended solution hence Autoboost application suggested for temporary gas lift considering the well remote location.
a concentric tubing 1.66’’ was run in the well for gas lift injection purpose.
Test results shown in fig.5 demonstrates the success of the operation and the overall process of Autoboost system. The system’s data acquisition offers a real time monitoring of the operating parameters and gas lift optimisation process by variation of Q ginj rate versus the produced oil at different WHP pressures controlled by choke size setting.
