Mumbai has always had a strong connection with India’s energy story. The city is close to offshore oil and gas operations, has major petroleum company headquarters, important refineries, corporate energy offices, fuel marketing networks, LPG distribution systems, CNG stations and piped gas infrastructure. From the ports of Mumbai to the offshore fields of the Arabian Sea, oil and gas businesses have helped power the city’s transport, industries, homes and commercial life.
In 2026, the oil and gas industry is also changing. Companies are not only focused on petrol, diesel, LPG and crude oil. They are also working on natural gas, cleaner fuels, petrochemicals, green energy, LNG, city gas distribution and energy security. Mumbai remains important because it connects corporate decision-making, offshore operations, refining, marketing, finance and national energy planning.
