Introduction
India’s oil and gas sector is one of the most vital pillars of its growing economy. With rising energy demand, expanding infrastructure, and greater private participation, the industry continues to evolve rapidly. As a result, many people ask: How many oil companies are there in India in 2025?
This article dives deep into the answer, covering the estimated number of companies, major players, industry categories, and FAQs to give you a full picture of the landscape.
How Many Oil Companies Are There in India in 2025?
Although there is no single official list that tracks every oil and natural gas company, industry databases and business registries estimate that India has between 1,687 and 2,930 oil and natural gas companies in 2025.
Why the wide range?
Because different databases count companies differently—some include only active companies, some track firms with more than five years in business, and others include service providers and gas-related companies as part of the sector.
In general:
Approximately 1,687 companies have over five years of operations.
Around 2,930 companies fall under the broader oil and natural gas category.
This includes public-sector undertakings (PSUs), private energy giants, exploration companies, refiners, LNG firms, service providers, and regional distributors.

Understanding the Oil Sector: Upstream, Midstream & Downstream
The oil industry is divided into three major segments:
🛢 Upstream – Exploration & Production
Includes companies dealing with discovering and extracting crude oil or natural gas.
Examples: ONGC, Oil India, HOEC
⚙️ Midstream – Transportation & Storage
Involves pipelines, LNG import terminals, and bulk storage.
Examples: Petronet LNG, pipeline divisions
⛽ Downstream – Refining & Marketing
Handles refining crude oil and distributing finished products like petrol, diesel, LPG, etc.
Examples: IOCL, BPCL, HPCL, Reliance
Why the Number of Oil Companies Varies
The number differs based on several factors:
Whether companies are fully operational or merely registered
Whether natural gas firms are included
If support and service companies are counted
Whether regional distributors are part of the list
If company age (e.g., more than five years in business) is considered
This is why most estimates present a range rather than a fixed number.
