Advantages and Disadvantages of the Gas Lift Process on Environment

After a long period of exploitation of natural resources, there is a requirement for helpful methods to continue operation from oil reservoirs. When the reservoir pressure decreases, the reservoir is not able to bring oil to the surface and can only direct the oil into the well column. One of the best methods for enhancing the production rate is using an artificial gas lift. In the gas lift system, by injecting gas into the well column and mixing the oil and gas, the liquid column becomes lighter, and as a result, the back pressure of the well column on the bottom hole pressure is reduced and It causes the pressure difference between the well and the reservoir to increase as well as the production. One of the important concerns in using this method is the environmental problems, which is decisive in using this method. Therefore, in this study, with the aim of investigating the environmental advantages and disadvantages of this method, the articles that have been published in this field are reviewed and the advantages and disadvantages of this method on the environment are categorized. According to the reviewed materials, it can be stated that although the use of this method involves environmental harm, the advantages of using this method are more compared to other methods and the harm can be controlled by planning.
