Principles and Practical Methods for Studying Gas Injection for Enhanced Oil Recovery in the Oil Fields of Iran; Using a Commercial Simulator

Gas injection is a technique that increases the recovery of oil fields in Iran. Considering that Iran is the world's second largest gas reserves, such projects will be economically reasonable. Therefore, in this study the performance of gas injection in one of Iran's oil reserves have been evaluated. In this article the mechanisms of oil gas drive is injected into the gas cap and the oil layer are examined, and the factors affecting the efficiency of gas injection will be evaluated by the commercial simulator software. To achieve the maximum percentage of oil recovery in the oil layer to the gas injection, gas injection rates higher than gas injection in the gas cap is required. we can say gas injection into the gas cap is more appropriate than oil layer, because in this case, gas can have faster diffusion into the gas production wells and will be caused early closed in productive well
