NEW DELHI: The Cabinet approved Samudra Manthan on July 31. Almost every account of it since has led with two things: the size of the cheque, ₹84,084 crore, and the promise of oil. Read the approval itself and a different scheme comes into view — one whose first and largest instrument is not a drill at all. It is a seismic survey.
The Cabinet note lists the interventions in order, and the order is the argument. First: “large-scale acquisition, processing and interpretation of high-quality seismic data.” Only then does it reach accelerated deepwater and ultra-deepwater exploratory drilling, and after that scientific drilling in frontier basins — which is drilling undertaken to find out what is there, not to produce from it. Then common offshore production and evacuation infrastructure. Then an integrated Oil and Gas Manufacturing and Services Zone. A scheme that ran to FY 2030-31 and produced no barrel of oil, but left behind a mapped continental shelf, shared pipelines and a domestic offshore-services industry, would still have delivered most of what this document actually commits to.
The expensive part is under the water, not on it: ultra-deepwater exploratory wells are among the costliest single objects a country can commission. Samudra Manthan’s sequencing — survey first, drill second — is designed so that fewer of them are drilled blind.
A dry well is not a failure of luck. It is usually a failure of information bought too late.
At a Glance
• Scheme: Samudra Manthan — National Offshore Exploration Scheme, a Central Sector Scheme of the Ministry of Petroleum & Natural Gas
• Approved: July 31, 2026, by the Union Cabinet
• Outlay: ₹84,084 crore, for implementation up to FY 2030-31
• Target: reserve accretion of over 600 Million Metric Tons of Oil Equivalent (MMTOE)
• Instruments, in the order listed: seismic acquisition → deepwater and ultra-deepwater drilling → scientific drilling in frontier basins → common production and evacuation infrastructure → an Oil & Gas Manufacturing and Services Zone
• Also provided for: digital programme management, capacity building, technology adoption, international outreach
• Origin: announced from the Red Fort on Independence Day 2025
Two words in the list deserve more attention than they have had. The first is “common”. Common offshore production and evacuation infrastructure means shared platforms and shared pipelines — the arrangement in which a small discovery becomes commercially viable because it can tie back into somebody else’s export line instead of funding its own. In offshore basins this single design choice decides which discoveries get developed and which are written off as too small, and it is the reason mature provinces elsewhere keep producing from fields that would never have justified standalone infrastructure. The second is “Zone”. An integrated Oil and Gas Manufacturing and Services Zone is an attempt to keep the supply chain onshore and Indian: the vessels, the subsea kit, the mud, the inspection, the maintenance. Offshore exploration is a business in which the great majority of the money is spent on services, not on the resource, and services are where employment and repeat revenue actually sit.
The honest framing is that 600 MMTOE of reserve accretion is a target, not a discovery, and geology does not take instruction. What can be said with confidence is that India has been buying the wrong thing in the wrong order for a long time — drilling on thin data, in acreage that had never been properly surveyed, and then treating the disappointing result as evidence that the basin was poor rather than that the map was. The reforms of the past decade opened almost the entire offshore acreage and rebuilt the National Data Repository; this scheme funds the surveys that make that acreage legible. The useful thing to watch over the next four years is therefore not the production number. It is the survey coverage: how many square kilometres of Indian shelf move from unmapped to mapped, and how quickly that data reaches the repository where any bidder can price it. That is the number which decides whether the drilling that follows is a bet or a calculation.
