Optimization of Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

**Abstract
** The optimization of enhanced oil recovery (EOR) techniques for mature oil fields is a critical aspect of petroleum engineering, aiming to maximize the extraction of oil reserves from depleted reservoirs. This thesis explores the various EOR methods and strategies that can be utilized to enhance oil recovery in mature oil fields. The research focuses on the challenges faced in mature oil fields, such as declining production rates and increasing water cut, and investigates how advanced EOR techniques can address these issues. The study begins with a comprehensive literature review of existing EOR methods, including polymer flooding, steam injection, gas injection, chemical flooding, and microbial EOR, among others. The review examines the effectiveness of each technique, their applicability to mature oil fields, and the factors influencing their success. By synthesizing information from previous studies, the research establishes a foundation for assessing the potential of different EOR methods in optimizing oil recovery from mature reservoirs. In the research methodology chapter, a detailed outline of the experimental approach and analytical techniques used to evaluate EOR performance in mature oil fields is provided. The methodology includes reservoir simulation studies, laboratory experiments, field trials, and economic analysis to assess the feasibility and effectiveness of EOR techniques. The research methodology aims to provide a systematic and rigorous framework for evaluating and comparing different EOR strategies. The findings chapter presents the results of the research, highlighting the performance of various EOR methods in enhancing oil recovery from mature oil fields. The discussion covers key parameters such as oil displacement efficiency, sweep efficiency, recovery factor, and economic viability of EOR techniques. The findings offer insights into the optimal selection and implementation of EOR methods based on reservoir characteristics, fluid properties, and operational considerations. The conclusion and summary chapter provide a concise overview of the research outcomes and key findings related to the optimization of EOR techniques for mature oil fields. The conclusion offers recommendations for future research directions, technology advancements, and practical strategies to improve oil recovery efficiency in mature reservoirs. This thesis contributes to the advancement of knowledge in petroleum engineering by proposing innovative solutions to enhance oil production from mature oil fields through effective EOR optimization strategies. Overall, this thesis underscores the importance of implementing advanced EOR techniques tailored to the specific challenges of mature oil fields to maximize oil recovery, extend field life, and optimize economic returns for operators and stakeholders. The research outcomes have implications for the sustainable development of mature oil fields and the efficient utilization of existing hydrocarbon resources in the global energy landscape.
