What the company or idea is
ONGC is India’s largest government-owned oil and gas explorer and producer, founded in 1956 and headquartered in Delhi.
How it actually makes money
ONGC makes money by exploring for, drilling, and producing crude oil and natural gas in India — then selling those commodities to refineries, power plants, and other industrial buyers.
What works
ONGC dominates domestic upstream output: it accounts for ~70% of India’s crude oil and ~84% of its natural gas production. Its scale and Maharatna status grant it operational autonomy and capital allocation powers rare among Indian PSUs.
What does not
ONGC does not control refining, marketing, or retail distribution; it remains upstream-only. It does not set domestic fuel prices, nor does it bear the cost of subsidies or price controls imposed by the government.
What to take from it
ONGC demonstrates how vertical integration stops at extraction — and how profitability as a central PSU reflects fiscal transfers and pricing regimes more than competitive advantage.
Is it worth your time
Yes — if you are assessing how state-owned energy incumbents operate, extract value, and respond to market shifts without private capital discipline.
