West Bengal Opens Four Districts for ONGC Oil & Natural Gas Exploration
West Bengal has taken a significant step towards strengthening its energy sector by granting the Oil and Natural Gas Corporation (ONGC) permission to begin oil and natural gas exploration across four districts, Murshidabad, Purba Bardhaman, Nadia and North 24 Parganas. The approval has been issued under the Petroleum & Natural Gas Rules, 2025, and is expected to pave the way for fresh investments, employment opportunities and higher royalty revenue for the state.
The approved exploration area spans approximately 2,872.6 square kilometres across Murshidabad, Purba Bardhaman and Nadia, while the Ashoknagar project in North 24 Parganas is projected to generate nearly ₹104 crore in revenue. The initiative marks one of the state's most important energy sector developments in recent years, as Bengal seeks to unlock its untapped hydrocarbon resources.
The latest approval builds upon earlier natural gas discoveries near Ranaghat in Nadia district and Kanakpur in North 24 Parganas. These findings have strengthened confidence in the state's hydrocarbon reserves and encouraged further exploration across multiple districts. If commercially viable reserves are discovered, the projects could significantly improve West Bengal's domestic energy production while reducing dependence on imported fossil fuels.
Beyond energy production, the exploration programme is expected to generate substantial economic benefits. Large-scale exploration activities typically create direct and indirect employment across drilling operations, engineering services, logistics, transportation, equipment supply and local support industries. Increased industrial activity could also stimulate demand for infrastructure development and ancillary businesses in the surrounding regions.
For the state government, successful exploration could translate into higher royalty earnings and additional revenue that can be reinvested in public infrastructure and development projects. The Ashoknagar project alone is expected to contribute around ₹104 crore, highlighting the financial potential of Bengal's emerging energy sector.
The move also aligns with India's broader objective of increasing domestic oil and natural gas production to enhance energy security. As industries continue to expand across West Bengal, a stronger local energy ecosystem could support manufacturing, chemicals, fertilisers and other energy-intensive sectors while improving long-term industrial competitiveness.
Over the past few years, West Bengal has witnessed growing investments across manufacturing, logistics, infrastructure and technology. The addition of hydrocarbon exploration to this momentum further diversifies the state's industrial landscape and reinforces its position as an emerging investment destination in eastern India.
While exploration is only the first stage and commercial production will depend on the discovery of economically viable reserves, the government's approval represents an important milestone. If successful, ONGC's exploration programme could unlock new opportunities for investment, employment, industrial development and energy security, contributing to West Bengal's long-term economic growth.
