ONGC, evolving from a directorate established in 1955, faced significant challenges including government control and overstaffing, which threatened its operational efficiency. Under Subir Raha's leadership, the company implemented a revitalized strategy focusing on global exploration, downstream integration, and improved internal processes, resulting in major growth in production and profits. Despite facing competition and internal conflicts, ONGC successfully signed key technology deals and launched multiple joint ventures to enhance its energy projects and asset monetization.
