Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study" aims to explore and compare various enhanced oil recovery (EOR) techniques that can be applied to mature oil fields. Mature oil fields are those that have been producing oil for an extended period and have experienced a decline in production rates. By investigating different EOR methods, this study seeks to identify the most effective techniques for revitalizing production in these fields. The research will begin with a comprehensive literature review to provide a background on the challenges faced by mature oil fields and the existing EOR technologies available. This review will cover topics such as water flooding, gas injection, chemical flooding, thermal methods, and emerging technologies in the field of EOR. By analyzing previous studies and case histories, the project aims to understand the advantages and limitations of each technique. Following the literature review, the research methodology will involve selecting a set of mature oil fields for comparative analysis. Data on reservoir characteristics, production history, and existing recovery mechanisms will be collected and analyzed to determine the most suitable EOR techniques for each field. This analysis will consider factors such as reservoir heterogeneity, fluid properties, well configuration, and economic feasibility. The core of the study will involve a detailed discussion of the findings from the comparative analysis. The effectiveness of different EOR methods in enhancing oil recovery rates, improving sweep efficiency, and extending the economic life of mature oil fields will be evaluated. The project will also assess the environmental impact, cost implications, and operational challenges associated with implementing these techniques. In conclusion, this research aims to provide valuable insights into the selection and implementation of EOR techniques for mature oil fields. By comparing the performance of various methods, the study seeks to offer recommendations for optimizing oil recovery in these challenging reservoirs. The findings of this project will contribute to the body of knowledge in petroleum engineering and provide practical guidance for operators and decision-makers in the oil and gas industry.
