Oil comes from fossils thousands of years ago and it's natural resources that can not be renewed. If it used continuously, the oil supplies will eventually run out. One way to optimize an oil production by using gas lift. Focus of this paper is to optimize the gas lift method by injecting gas into the wells so more oil will be produced. Gbest-guided Artificial Bee Colony (GABC) will became the optimization techniques while Least Square method used to make the mathematical model from the correlation between gas injection and oil production. The purpose of this research is to maximize oil production and minimize the gas injection. The selected model has a 10th order polynomial with R-square value of 1 and Sum of Squares Error (SSE) is 34.091. GABC will optimize the model and it will be compared to another optimization method such as Artificial Bee Colony (ABC). The results are GABC better than ABC for each case with 4812.877 barrel oil per day (Bopd), 5107.873 Bopd, and 5142.156 Bopd respectively, while the best C values in GABC method is 2.
