Behind every barrel of oil lies a complex struggle for control—between nations guarding sovereignty and corporations pursuing profit. National Oil Companies vs Majors: Who Really Controls the Flow investigates the century‑long rivalry shaping the global energy landscape. From the post‑colonial birth of national oil giants to the dominance of Western "majors," the book reveals how access, pricing, and technology became instruments of geopolitical power. Drawing on history, policy, and markets, it unpacks how governments and corporations negotiate the balance between resource nationalism and global integration. The result is a powerful exploration of who truly governs the world's most vital commodity—and at what cost.
