NEW DELHI: The Cabinet’s Samudra Manthan scheme carries an outlay larger than most Indian infrastructure programmes and a target of 600 million tonnes of oil equivalent. Read the components and it becomes clear that this is not primarily a drilling programme. It is a data programme.
Approved on August 1 as a Central Sector Scheme of the Ministry of Petroleum and Natural Gas, Samudra Manthan runs to FY2030-31 with an outlay of ₹84,084 crore. It covers the offshore exploration value chain end to end — geological survey, deep-sea drilling, scientific research, production infrastructure, digital monitoring, manufacturing support and skill development — with an explicit focus on deepwater and ultra-deepwater acreage. The stated expectation is reserve accretion of more than 600 million tonnes of oil equivalent. Its single largest component is the acquisition, processing and interpretation of high-quality seismic data across India’s offshore sedimentary basins, followed by scientific drilling in frontier basins where geological information remains thin.
Before the rig: most of the early outlay buys seismic surveys and scientific wells — the information that determines whether anyone bids for a block at all.
Nobody bids for acreage they cannot picture. The most expensive thing about an unexplored basin is not the drilling — it is the not knowing.
At a Glance
• Approved: August 1, 2026, by the Union Cabinet
• Outlay: ₹84,084 crore, running to FY2030-31
• Type: Central Sector Scheme of the Ministry of Petroleum and Natural Gas
• Focus: deepwater and ultra-deepwater offshore sedimentary basins
• Largest component: large-scale seismic data acquisition, processing and interpretation
• Second component: scientific drilling in frontier basins with limited geological information
• Target: reserve accretion of over 600 million tonnes of oil equivalent
• Also covers: production infrastructure, digital monitoring, indigenous manufacturing support and skilling
The economics of that sequencing are worth stating plainly, because they explain why a state scheme rather than a licensing round. Exploration risk in a frontier basin is close to unpriceable: a company asked to bid for a block with sparse seismic coverage has no basis on which to value it, and the rational response is to bid low or not at all. Public acquisition of high-quality seismic data converts that unknown into a distribution — still risky, but now a risk with a number attached. That is precisely the function of a national data repository, and it is why the money spent on surveys before any commercial well is drilled tends to be the highest-return money in the programme. The commercial bidding that follows is where private capital enters, and it will enter on better terms because the information asymmetry has been reduced.
Two things should temper expectations without diminishing the case. Reserve accretion is not production: 600 million tonnes of oil equivalent identified is a resource statement, and the interval between a discovery and first commercial output in deepwater is typically measured in years, not quarters. And the manufacturing and skilling components matter more than their line-item size suggests — India’s offshore services capability, from vessels to subsea engineering, is thinner than its exploration ambition, and this scheme is one of the few instruments that could deepen it. Handled well, the return here is threefold: better geological knowledge that lowers the cost of every future licensing round, a domestic offshore supply industry, and whatever hydrocarbons follow. Handled as a drilling target alone, it would be the least valuable version of a good idea.
