This book provides a structured introduction to petro-economics, examining the economic principles, market structures, and strategic forces that shape the global petroleum sector. It explains how oil resources are valued, developed, traded, and managed within national and international contexts. The discussion integrates concepts of supply and demand, pricing behaviour, investment decision-making, risk, and policy influence, showing how economic factors interact with technology and geopolitics. Attention is given to industry organisation, corporate scale, market power, and long-term resource planning. The book also considers future energy transitions, fiscal regimes, and sustainability pressures that influence petroleum economics. By combining analytical frameworks with real-world industry perspectives, it builds a coherent foundation for understanding economic decision-making across the oil and gas value chain.

It is intended for students, researchers, policymakers, and professionals in energy economics, petroleum studies, and management. The book serves as an academic reference and practical guide for analysing petroleum markets, corporate strategy, fiscal systems, and future investment choices, supporting informed economic evaluation and policy understanding within a changing global energy environment and long-term strategic planning across public and private energy institutions globally.
