Abstract
In this study, the AW-A well of Ahvaz oil field was investigated which is threatened due to closed flow pressure drop. The study and optimization of the AW-A well has been done by mixing three natural production options from the well, modifying the internal structure of the well by driving the tubing and applying different percentages of produced water and applying the artificial production system (with gas injection). In this study, it was tried to bring the general information related to the Black Oil route closer to the reality according to the compositional information, and then the other studies were conducted based on the Black Oil route. In this research, PIPESIM software was used to simulate the gas lift in one of the wells of the Ahvaz oil field and the effect of changing the size and depth of the tubing and comparing the effect of production from different tubings and the most optimal diameter and depth of the tubing. The most suitable and optimal option was gas lift method according to the simulation, so that the production rate can be increased to 2217 barrels per day in the current conditions of the reservoir.
