Thesis Abstract

Abstract
The optimization of hydraulic fracturing parameters for enhanced oil recovery in unconventional reservoirs is a critical aspect of petroleum engineering that seeks to maximize the extraction of oil from challenging geological formations. This thesis investigates the various factors that influence the efficiency of hydraulic fracturing operations in unconventional reservoirs and aims to develop a comprehensive framework for optimizing these parameters. The study begins with a detailed review of the background and current state of hydraulic fracturing technology, highlighting the challenges and opportunities for improvement in unconventional reservoirs. The research methodology employed in this study includes a combination of theoretical analysis, numerical simulations, and field experiments to evaluate the impact of different fracturing parameters on oil recovery rates. Through a systematic literature review, key insights are gathered on the best practices and emerging trends in hydraulic fracturing optimization, laying the foundation for the experimental phase of the study. The research methodology chapter outlines the data collection methods, simulation techniques, and statistical analyses used to evaluate the performance of various hydraulic fracturing parameters. The discussion of findings chapter presents the results of the numerical simulations and field experiments, providing a detailed analysis of how different fracturing parameters affect oil recovery efficiency in unconventional reservoirs. By examining factors such as proppant concentration, injection rate, fluid type, and well spacing, the study identifies the optimal combination of parameters that lead to the highest oil recovery rates. The findings also reveal the importance of geomechanical properties, reservoir characteristics, and operational practices in determining the success of hydraulic fracturing operations. In conclusion, this thesis offers a comprehensive framework for optimizing hydraulic fracturing parameters in unconventional reservoirs to enhance oil recovery rates. The study underscores the significance of considering a holistic approach that integrates geological, engineering, and operational factors to achieve optimal results. By providing insights into the key factors influencing hydraulic fracturing efficiency, this research contributes to the advancement of oil recovery technologies in unconventional reservoirs and lays the groundwork for future research in this field.
