What Is Petroleum Economics? Concept, Scope and Industry Impact

Petroleum economics is the essential study of how oil and gas are valued, produced, priced and traded, and how those decisions reach businesses, governments, and households.

2026 has shown why it matters, tanker traffic through the Strait of Hormuz has been severely restricted, and the IEA now expects global oil demand to fall by 2.5 million barrels a day this year.

For anyone working in the petroleum industry, from engineers to finance teams, understanding the foundation of economics behind it is a vital part of the job. This guide covers what petroleum economics means, what it studies, how the industry is structured, and how markets and policy shape each other.
