New Delhi: When Prime Minister Narendra Modi stood at the Red Fort on Independence Day 2025 and invoked the ancient legend of Samudra Manthan, the churning of the cosmic ocean by gods and demons to draw out the nectar of immortality, he was making a promise about India's energy future. Thirteen months later, the Union Cabinet has translated that promise into a Rs 84,084 crore scheme that represents one of the most ambitious offshore energy programmes ever undertaken by an Indian government.
The Union Cabinet, chaired by Prime Minister Modi, has approved Samudra Manthan, the National Offshore Exploration Scheme, a Central Sector Scheme of the Ministry of Petroleum and Natural Gas with an approved outlay of Rs 84,084 crore for implementation up to FY 2030-31.
The timing is not incidental. India's oil import bill stands at approximately $144 billion annually. The Strait of Hormuz, through which a significant portion of India's oil supply transits, has been contested and periodically closed since February 2026 as a consequence of the US-Iran war. Houthi attacks on Saudi Arabia's Yanbu export terminal on July 26 threatened the alternate Red Sea route. India imports 88 to 89 percent of its crude oil and approximately half of its natural gas. As recent geopolitical developments have demonstrated, secure and uninterrupted access to energy resources is of strategic importance for a rapidly growing economy.
Samudra Manthan is India's structural response to that strategic vulnerability.
What the Scheme Does: Five Pillars and a Rs 84,084 Crore Budget
The scheme is not a single intervention, it is a comprehensive framework spanning the entire offshore exploration and production value chain, from seismic mapping of unexplored ocean floors to the physical infrastructure needed to bring discovered hydrocarbons to market.
Samudra Manthan is a comprehensive offshore exploration programme covering the entire oil and gas exploration value chain. Unlike conventional schemes focused only on exploration, the initiative integrates geological surveys, deep-sea drilling, scientific research, production infrastructure, digital monitoring, manufacturing support and skill development under a single national framework.
Pillar One: Seismic Surveys, Rs 28,500 Crore
The programme's first and foundational pillar is the acquisition, processing, and interpretation of high-quality seismic data across India's offshore sedimentary basins. Rs 28,500 crore will be spent on advanced 2D and 3D seismic surveys and data processing technologies, including artificial intelligence, to identify areas that may contain large hydrocarbon reserves.
2D seismic surveys provide a linear cross-section of subsurface geology, useful for identifying general structures. 3D seismic surveys provide a volumetric image of subsurface geology, far more accurate for identifying reservoir geometries, fault structures, and hydrocarbon traps. The integration of AI-driven data processing represents the most significant methodological advance from previous seismic survey programmes: machine learning algorithms can identify patterns in seismic data that human interpreters might miss, significantly increasing the hit rate for exploratory drilling.
India's offshore sedimentary basins, the Krishna-Godavari basin, the Cauvery basin, the Mahanadi basin, the Indus basin, the Andaman basin, and several frontier basins in deep and ultra-deep water,, contain geological formations that have been identified as potentially hydrocarbon-rich through earlier surveys but have never been comprehensively mapped at modern seismic resolution. Samudra Manthan will change that.
Pillar Two: Deep-Sea Drilling, Rs 43,200 Crore
The scheme provides for drilling of 60 deepwater and ultra-deepwater exploration wells with an allocation of Rs 43,200 crore, including government support of up to 50 percent of eligible drilling cost or Rs 675 crore per well, whichever is lower.
This is the scheme's largest single allocation and its most critical operational component. Exploratory drilling is the only way to confirm whether geological structures identified in seismic surveys actually contain commercial quantities of hydrocarbons. Of India's current producing offshore fields, a disproportionate number are in relatively shallow water, the Mumbai High field, which has supplied a large share of India's domestic oil production for four decades, is a medium-depth offshore field. India's ultra-deepwater zones, water depths of 1,500 metres and beyond have been surveyed but not extensively drilled, largely because ultra-deepwater drilling is extraordinarily expensive.
The government's 50 percent cost support, with a ceiling of Rs 675 crore per well, represents a risk-sharing model designed to incentivise private and international operators, who currently view India's ultra-deepwater basins as commercially risky to participate. By bearing half the drilling cost, the government absorbs the financial risk that has historically deterred private investment in frontier basins.
Pillar Three: Common Offshore Infrastructure, Rs 10,000 Crore
Rs 10,000 crore for common offshore infrastructure hubs will facilitate commercialisation of discoveries, particularly for regions such as the Mahanadi and Kutch basins that have remained commercially unviable because of high transportation costs.
This pillar addresses one of the most persistent structural failures in India's offshore exploration history: the discovery-to-production gap. India has made a number of offshore hydrocarbon discoveries over the past two decades that have never been brought into commercial production, not because the reserves are insufficient, but because the infrastructure needed to transport the discovered oil or gas to shore is not available and cannot be built economically for a single small field.
The common offshore infrastructure model, in which pipeline networks, processing platforms, and subsea infrastructure are built as shared assets that multiple small-to-medium fields can connect to, is the same approach that made the development of North Sea marginal fields economically viable from the 1990s onward. By investing Rs 10,000 crore in such shared infrastructure, the government is attempting to unlock discoveries that are already on the books but sitting undeveloped.
The Mahanadi basin located in the Bay of Bengal offshore Odisha, has long been identified as having significant hydrocarbon potential. It is also one of the areas where transportation cost has been the primary barrier to development. The Kutch basin, offshore Gujarat, faces similar dynamics.
Pillar Four: Oil and Gas Manufacturing and Services Zone, Rs 2,000 Crore
Rs 2,000 crore will establish an integrated Oil and Gas Manufacturing and Services Zone to promote domestic manufacturing and localisation of critical equipment and services.
India currently imports virtually all of the specialised equipment needed for offshore exploration and production, drilling rigs, subsea wellheads, blowout preventers, pipe and tubing, seismic acquisition vessels, remotely operated vehicles, and the specialised software used for seismic interpretation. This import dependence creates both a cost burden and a supply chain vulnerability, as demonstrated during the Hormuz crisis when disrupted shipping logistics affected the availability of spare parts and equipment for India's existing offshore operations.
The Manufacturing and Services Zone is designed to develop domestic production capability for at least some of this equipment connecting the offshore energy programme to the Make in India initiative and creating an industrial ecosystem that could, over time, serve not only India's own offshore sector but export markets across the developing world.
Pillar Five: Scientific Drilling and Skill Development
Beyond the four quantified pillars, Samudra Manthan includes provisions for scientific drilling in frontier basins drilling specifically aimed at improving geological understanding rather than immediate commercial discovery and for developing the human capital needed to operate a world-class offshore energy industry at scale. India currently relies heavily on international expertise for deepwater drilling and subsea operations. Building that expertise domestically is a decade-long project that must begin now if it is to bear fruit by the 2030s.
What India Hopes to Find: The Reserve Targets
Samudra Manthan is expected to catalyse reserve accretion of over 600 Million Metric Tons of Oil Equivalent, substantially increase offshore exploration activity, promote higher domestic oil and gas production, generate large-scale employment, strengthen indigenous manufacturing under Make in India and Atmanirbhar Bharat, and foster a globally competitive ecosystem for offshore technologies and services.
The scheme aims to increase India's domestic oil and gas production from around 62 million metric tonnes of oil equivalent to 80 MMTOE annually and expand the country's hydrocarbon resource base from 1.6 billion tonnes of oil equivalent to 2.2 billion tonnes of oil equivalent.
To contextualise the 600 MMTOE target: India's current domestic oil production is approximately 29-30 million tonnes of crude per year, supplemented by natural gas production of approximately 34 billion cubic metres. If the scheme achieves its stated targets adding 600 MMTOE to the reserve base over the implementation period, it would represent an increase of approximately 37 percent in India's total hydrocarbon resource base. That would not eliminate import dependence, India's consumption is growing too rapidly for domestic production alone to meet it, but it would meaningfully reduce the proportion of consumption that must be imported, cutting the import bill and reducing exposure to the kind of geopolitical shocks that the Hormuz crisis has made painfully visible.
Why Now: The Geopolitical Case for Domestic Energy
The government's official statement on Samudra Manthan is explicit about the geopolitical context: India's $144 billion annual crude import bill, which represents approximately 3.5 percent of GDP, is a structural vulnerability. Every dollar increase in the international oil price costs India approximately Rs 9,000-10,000 crore in additional import expenditure annually. The Hormuz crisis of 2026 demonstrated with unusual clarity what happens when that import dependence collides with geopolitical reality.
India's energy security strategy has historically rested on three pillars: supply diversification across multiple producing countries, strategic petroleum reserves sufficient for approximately 9-10 days of consumption, and long-term supply agreements with major producers including Saudi Arabia, Iraq, UAE, and Russia. Samudra Manthan adds a fourth pillar, domestic production growth to that architecture.
The scheme also fits within a broader pattern of Indian economic nationalism that has accelerated since 2020. Just as the Production Linked Incentive schemes sought to domesticise manufacturing of electronics, pharmaceuticals, and automobiles, Samudra Manthan seeks to domesticise a significant portion of India's energy supply. The Atmanirbhar Bharat framing, self-reliant India, applies to hydrocarbons as directly as it applies to semiconductors.
The Bigger Picture: Samudra Manthan in India's Energy Transition
Samudra Manthan is a hydrocarbons scheme, oil and gas, not renewables. It is being launched at a moment when India has simultaneously committed to one of the world's most ambitious renewable energy programmes, targeting 500 GW of non-fossil fuel electricity capacity by 2030. The two commitments are not contradictory, they reflect a realistic assessment that India's energy consumption is growing fast enough to require both renewable electricity growth and domestic hydrocarbon production growth simultaneously, with energy security considerations making both urgent.
The scheme's name, borrowed from the ancient myth of cosmic ocean-churning that produced both poison and nectar is appropriate. Offshore exploration is precisely that kind of endeavour: immensely expensive, uncertain in outcome, capable of producing transformative discoveries or yielding nothing, and requiring the patience to churn the depths long enough for the treasure, if it is there, to emerge.
India is about to start churning. What comes up from the deep will take years to know.
