Optimization of Enhanced Oil Recovery Techniques in Mature Oilfields

Thesis Abstract

Abstract
The petroleum industry is constantly seeking innovative ways to enhance oil recovery from mature oilfields to maximize production and economic returns. This thesis focuses on the optimization of enhanced oil recovery (EOR) techniques in mature oilfields, aiming to improve recovery factors and extend the life of these assets. The research examines various EOR methods, including chemical, thermal, and microbial techniques, to identify the most effective strategies for specific reservoir conditions. The study begins with a comprehensive review of the background and significance of EOR in mature oilfields, highlighting the challenges and opportunities associated with implementing these techniques.
