Chennai’s oil and gas industry does not sit in glass towers alone. It lives in the refinery flames of Manali, the fuel tankers moving through Ennore, the LPG cylinders reaching hotels and homes, the petrol pumps lighting up highways, and the gas pipelines slowly changing how buses, factories, and commercial kitchens consume energy. In 2026, Chennai remains one of South India’s most important energy centres because it combines refinery capacity, port access, industrial demand, LPG distribution, LNG infrastructure, and a growing city gas network.
The city’s oil and gas strength is closely linked with North Chennai’s industrial belt, especially Manali and Ennore. Manali is home to one of South India’s oldest and most important refineries, while Kamarajar Port at Ennore handles POL, LPG, chemicals, and other liquid cargo. The port area is also connected with LNG infrastructure, making Chennai important not only for petroleum products but also for cleaner gas-based energy.
Here is a carefully researched list of the Top 5 Oil and Gas Companies in Chennai in 2026, selected on the basis of Chennai presence, refining strength, fuel distribution, gas infrastructure, market reach, and importance to Tamil Nadu’s energy economy.
1. Chennai Petroleum Corporation Ltd. (CPCL)
- Founded: 1965
- Type: Public Sector / Listed Oil Refining Company
- Address: 536, Anna Salai, Teynampet, Chennai – 600018, Tamil Nadu, India

Overview
Chennai Petroleum Corporation Ltd., commonly known as CPCL, is the most important oil and gas company headquartered in Chennai. Formerly known as Madras Refineries Limited, CPCL is a subsidiary of Indian Oil Corporation and plays a central role in refining crude oil into usable petroleum products.

It produces petrol, diesel, LPG, aviation turbine fuel, kerosene, naphtha, bitumen, lube base stocks, paraffin wax, fuel oil, and petrochemical feedstocks. This makes CPCL not just a fuel company but also a mother industry for several downstream units in the Manali industrial belt.
In FY26, CPCL delivered a major turnaround. Its net profit surged to ₹3,062 crore from ₹174 crore in FY25, supported by record crude throughput, better refining margins, and improved operational efficiency. The company processed 11.71 million metric tonnes of crude in FY26, above its Manali nameplate capacity, showing strong refinery utilisation.
Key Highlights
CPCL is strong in petroleum refining, LPG, diesel, petrol, aviation fuel, lube base stocks, wax, and petrochemical feedstocks. In June 2026, CPCL was also granted Navratna CPSE status, giving it greater financial and operational autonomy.
For Chennai’s oil and gas industry, CPCL is the clear number one.
2. Indian Oil Corporation Ltd. (IndianOil)
- Founded: 1959
- Type: Public Sector Oil and Gas Company
- Address: Corporate Office: New Delhi, India

Overview
Indian Oil Corporation is India’s largest government-owned oil and gas company and one of the most important energy companies operating in Chennai. While its headquarters is in New Delhi, its Chennai relevance is very strong because of its fuel retail network, Indane LPG distribution, lubricant business, pipeline connectivity, CPCL subsidiary relationship, and LNG-related presence at Ennore.
IndianOil’s business covers the full hydrocarbon chain: refining, pipelines, petroleum product marketing, petrochemicals, natural gas, exploration and production, lubricants, LPG, and clean-energy initiatives. It also owns a majority stake in CPCL, which directly connects it to Chennai’s refining base.
IndianOil’s Ennore LNG terminal is especially important for Chennai’s future energy system. LNG is brought in, regasified, and supplied through pipelines to industries in and around Manali and other parts of Tamil Nadu. Kamarajar Port references IndianOil’s LNG import terminal at Ennore, built with 5 million tonnes per annum capacity and expandable further.
Key Highlights
IndianOil is strong in petrol, diesel, LPG, lubricants, natural gas, pipelines, LNG, petrochemicals, and large-scale energy distribution.
For Chennai, IndianOil is important because it connects refinery output, fuel retail, LPG distribution, and cleaner gas infrastructure into one large energy ecosystem.
3. Bharat Petroleum Corporation Ltd. (BPCL)
- Founded: 1976
- Type: Public Sector Oil and Gas Company
- Address: Corporate Office: Mumbai, Maharashtra, India
- Chennai Presence: Fuel retail, Bharatgas LPG distribution, lubricants, industrial fuels, and commercial energy services across Chennai and Tamil Nadu
Overview
Bharat Petroleum Corporation Ltd., or BPCL, is another major oil and gas company with strong Chennai operations. Though headquartered in Mumbai, BPCL has a deep national distribution network that serves Chennai through petrol pumps, Bharatgas LPG agencies, industrial fuel supply, lubricants, and commercial energy services.
BPCL is India’s second-largest government-owned downstream oil producer and operates in petroleum products, natural gas, LNG, lubricants, petrochemicals, and retail fuel distribution. It also has interests in gas and energy through subsidiaries and joint ventures.
In Chennai, BPCL’s importance is most visible in LPG and retail fuel distribution. Hotels, restaurants, households, transport users, and industries depend heavily on regular supply from oil marketing companies like BPCL and IndianOil. A 2026 report on LPG pressure in Chennai specifically mentioned major oil companies such as IndianOil and BPCL in connection with commercial LPG supply disruption, showing how closely the city’s hospitality and service economy depends on them.
Key Highlights
BPCL is strong in petrol, diesel, LPG, aviation fuel, lubricants, industrial fuels, and gas-linked businesses.
For Chennai customers, BPCL remains one of the most visible oil and gas companies through Bharatgas, fuel stations, and commercial energy supply.
4. Hindustan Petroleum Corporation Ltd. (HPCL)
- Founded: 1952
- Type: Public Sector Oil and Gas Company
- Address: Corporate Office: Mumbai, Maharashtra, India
- Chennai Presence: Fuel retail, HP Gas LPG distribution, lubricants, industrial fuels, and petroleum product supply across Chennai and Tamil Nadu
Overview
Hindustan Petroleum Corporation Ltd., commonly known as HPCL, is a major Indian oil and gas company with strong presence across Chennai’s fuel and LPG market. It is a subsidiary of ONGC and operates in petroleum products, natural gas, LNG, lubricants, petrochemicals, and retail distribution.
In Chennai, HPCL is important because of its petrol pumps, HP Gas distribution network, lubricants, and industrial fuel supply. For ordinary consumers, HPCL is often seen through fuel stations and LPG cylinders, but behind that is a large supply-chain network involving storage, transport, safety systems, dealer operations, and regulatory compliance.
HPCL also plays a role in serving transport, small industries, commercial kitchens, fleet operators, and household customers. In a city like Chennai, where fuel demand comes from cars, bikes, buses, trucks, ports, logistics, factories, restaurants, and households, HPCL remains a crucial downstream energy player.

5. Torrent Gas Chennai Pvt. Ltd.
- Founded: Parent company Torrent Group founded in 1959; Torrent Gas incorporated later
- Type: City Gas Distribution Company
- Address: Chennai / Tiruvallur City Gas Distribution Presence, Tamil Nadu, India
- Service Area: Chennai and Tiruvallur region
Overview
Torrent Gas Chennai Pvt. Ltd. is an important name in Chennai’s changing gas economy. Unlike refinery and petrol companies, Torrent Gas focuses on city gas distribution — mainly CNG for vehicles and piped natural gas for homes, industries, and commercial users.
This category is becoming more important because cities are slowly moving toward cleaner fuels. In 2025, Chennai’s Metropolitan Transport Corporation signed agreements with Torrent Gas Chennai Pvt. Ltd. and THINK Gas to set up CNG filling stations for buses. Torrent Gas was assigned operations in Chennai and Tiruvallur, while THINK Gas was connected with Kancheepuram and Chengalpet.
This makes Torrent Gas especially relevant in 2026. If Chennai’s bus fleet, commercial vehicles, hotels, apartments, and industries increase CNG and PNG usage, city gas companies will become more visible in daily life.
Key Highlights
Torrent Gas is strong in CNG stations, piped natural gas, cleaner urban fuel distribution, and city-level gas infrastructure.
For Chennai’s future energy transition, Torrent Gas is one of the most important names to watch.
Conclusion
Chennai’s oil and gas industry in 2026 is led by CPCL in refining, IndianOil in integrated energy, BPCL and HPCL in fuel and LPG distribution, and Torrent Gas in city gas expansion. Together, these companies keep Chennai’s homes, hotels, factories, buses, vehicles, and industries running.
