NEW DELHI — The Union Cabinet, chaired by Prime Minister Narendra Modi, approved a landmark ₹84,084-crore National Offshore Exploration Scheme named “Samudra Manthan” on July 31, setting in motion what officials describe as India's most ambitious offshore hydrocarbon exploration mission to date — a decision that continued to keep oil and gas stocks including ONGC, Oil India and Reliance Industries firmly in market focus as trading resumed on Monday, August 3.
Approved as a Central Sector Scheme of the Ministry of Petroleum & Natural Gas, Samudra Manthan carries a Phase-I outlay of ₹84,084 crore for implementation through the 2030-31 financial year. The scheme's name draws directly on the ancient Indian legend of the churning of the cosmic ocean — a deliberate framing that officials say translates Prime Minister Modi's vision, first articulated during his Independence Day address from the Red Fort in 2025, of undertaking a “modern-day Samudra Manthan” to unlock the vast energy wealth believed to lie beneath India's offshore waters.
The scheme's structure is genuinely comprehensive in scope, integrating four core components across the offshore exploration value chain: large-scale acquisition, processing and interpretation of high-quality seismic data across previously underexplored offshore basins; accelerated drilling of 60 deepwater and ultra-deepwater exploratory wells; development of common infrastructure hubs designed to reduce the capital costs individual exploration companies would otherwise bear; and the establishment of dedicated manufacturing zones aimed at building indigenous capability in the specialized equipment and technology that offshore exploration and production requires.
Union Minister Ashwini Vaishnaw, announcing the Cabinet's decision, described Samudra Manthan as “a very ambitious programme” aimed squarely at unlocking India's offshore hydrocarbon potential. “Our Exclusive Economic Zone has a lot of hydrocarbons, gas and oil. If its exploration is done properly, then we can do a lot of production in India,” Vaishnaw said during the Cabinet briefing, framing the initiative as a direct response to India's growing energy demand and its continued heavy reliance on imported crude.
The strategic rationale underpinning the scheme is stark. India remains the world's third-largest consumer of crude oil, with an annual import bill of nearly $144 billion — approximately ₹13 lakh crore — according to the Ministry of Petroleum & Natural Gas. That scale of import dependence carries direct exposure to exactly the kind of geopolitical volatility that has periodically roiled global oil markets over the past year, including the recent bout of U.S.-Iran tensions that sent crude prices swinging sharply before easing again over the weekend heading into Monday's trading session. Government officials have explicitly cited these recent geopolitical developments as underscoring the strategic importance of secure, uninterrupted domestic energy access for a rapidly growing economy.

The government projects that Samudra Manthan could catalyze reserve accretion of over 600 million metric tonnes of oil equivalent (MMTOE), while lifting India's domestic oil and gas production from a current baseline of roughly 62 MMTOE to a targeted 80 MMTOE annually. Officials estimate that this additional production has the potential to reduce India's crude oil import bill by nearly ₹1 lakh crore annually — a substantial figure that, if realized, would meaningfully improve India's current account position and reduce the country's vulnerability to imported energy price shocks of exactly the kind witnessed repeatedly over recent years.
A particularly notable structural feature of the scheme is its financial support mechanism: the government will provide financial support covering up to 50% of the cost of drilling deepwater exploration wells, a direct subsidy designed to reduce the substantial capital risk inherent in offshore exploration and thereby encourage greater private and public sector investment in a segment of the energy value chain that has historically been characterized by high upfront costs, long gestation periods, and genuine geological uncertainty regarding whether exploration efforts will ultimately yield commercially viable discoveries.
That risk-sharing rationale reflects a broader structural challenge the scheme's architects have explicitly acknowledged: hydrocarbon exploration is a capital-intensive, long-gestation activity, typically requiring five to ten years between the award of an exploration block and the commencement of commercial production. Compounding that challenge, existing oil and gas fields globally — India's included — experience natural production decline rates of roughly 6-7% annually, meaning that without continuous, sustained new exploration and discovery, even a country's existing production base will steadily erode over time absent active reinvestment in finding and developing new reserves.
Samudra Manthan builds on a series of structural reforms the government has pursued since 2014 to create a more favorable ecosystem for hydrocarbon exploration and production, including the removal of more than 99% of previously designated “No-Go” areas that had historically restricted exploration activity, opening up more than one million square kilometres of India's Exclusive Economic Zone to potential exploration that was previously off-limits. Beyond its direct energy security objectives, the scheme is also positioned as an economic development initiative in its own right — officials project it will generate large-scale employment, strengthen indigenous manufacturing capability under the government's Make in India and Atmanirbhar Bharat (self-reliant India) initiatives, and help build a globally competitive ecosystem for offshore exploration technologies and services within India.
For India's listed oil and gas companies — ONGC, Oil India and Reliance Industries chief among them, given their existing offshore exploration and production footprints — Samudra Manthan represents both a direct commercial opportunity and a signal of sustained, long-term government policy commitment to the sector. Market attention on these stocks is likely to remain elevated in the weeks and months ahead as the scheme moves from Cabinet approval into implementation, with investors watching closely for details on block allocation processes, the specific companies selected to lead exploration activity in newly opened offshore basins, and early indications of exploration success as seismic surveys and deepwater drilling activity ramps up under the new national mission.
