Project Abstract

Abstract
Enhanced oil recovery (EOR) techniques play a crucial role in maximizing hydrocarbon production from mature oil fields. This comparative study aims to evaluate and compare various EOR techniques to determine their effectiveness in enhancing oil recovery from mature oil fields. The research focuses on the analysis of primary, secondary, and tertiary recovery methods, including water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR. The study investigates the technical, economic, and environmental aspects of each technique to provide insights into their applicability and success in different reservoir conditions.

Water flooding remains a widely used method due to its simplicity and relatively low cost, while gas injection and thermal methods show promising results in certain reservoir conditions. Chemical flooding and microbial EOR offer innovative solutions but require further research and field testing for widespread application. Overall, this comparative study provides valuable insights for oil and gas operators to optimize production from mature oil fields using advanced EOR techniques.
