NEW DELHI: The Cabinet has approved Samudra Manthan, a national offshore exploration scheme with an outlay of ₹84,084 crore running to FY 2030-31. Its stated target is reserve accretion of more than 600 million metric tonnes of oil equivalent. Set that against the structural number it is meant to address and the scale of the task becomes clear.
India’s dependence on imported crude has risen from roughly 55 per cent at the end of the 1990s to above 88 per cent today, and the reason is not falling domestic production so much as rising domestic consumption — petroleum product consumption has grown from about 90.6 million tonnes to roughly 243 million tonnes over the same period. Import dependence, in other words, is a demand statistic as much as a supply one. Any exploration programme, however well funded, is fighting a denominator that grows every year. That is the honest framing, and it is the framing in which 600 MMTOE of reserve accretion should be read: not as independence, but as a reduction in the rate at which the gap widens.
What the money actually buys: the largest line in an offshore exploration programme is not drilling but seismic data — acquisition, processing and interpretation determine where the expensive holes get drilled.
Exploration spending is the one industrial outlay whose principal output, most of the time, is the knowledge that a particular place is empty. That is not waste. That is the product.
At a Glance
• Scheme: Samudra Manthan, the National Offshore Exploration Scheme — a central sector scheme of the Ministry of Petroleum & Natural Gas
• Outlay: ₹84,084 crore, for implementation up to FY 2030-31
• Approved: by the Union Cabinet, July 31, 2026
• Target: reserve accretion of over 600 million metric tonnes of oil equivalent
• Components: large-scale seismic acquisition, processing and interpretation; accelerated deepwater and ultra-deepwater exploratory drilling; scientific drilling in frontier basins
• Infrastructure: common offshore production and evacuation facilities, and an integrated Oil & Gas Manufacturing and Services Zone
• Context: crude import dependence above 88 per cent; petroleum product consumption around 243 million tonnes
• Prior reforms cited: opening almost the entire offshore acreage, modernising the contractual framework, strengthening the National Data Repository
The component that deserves an investor’s attention is the least dramatic one: seismic data acquisition, processing and interpretation, funded at scale by the state. Offshore exploration fails commercially not because drilling is expensive but because drilling in the wrong place is expensive. Good seismic coverage is what converts a frontier basin from a gamble into a risked prospect, and it is a classic public good — costly to acquire, cheap to copy, and therefore chronically under-supplied by private operators who cannot capture its full value. A government that buys the seismic and puts it in a national data repository is doing the single thing most likely to attract private drilling capital afterwards. The same logic sits behind the common production and evacuation infrastructure in the scheme: shared pipelines and platforms lower the minimum discovery size that is worth developing, which turns marginal finds into producing fields.
Two constraints will determine whether the 600 MMTOE target is met, and both are addressable. The first is rig availability. Deepwater and ultra-deepwater drilling units are a globally tight market on multi-year charters, and a five-year programme that has to compete for them in a strong cycle will pay for the privilege — which is one argument for the integrated manufacturing and services zone the scheme also funds, since domestic fabrication and servicing capability is what eventually softens that exposure. The second is time. Exploration to first oil in deep water runs to the better part of a decade; a scheme ending in FY31 will book most of its discoveries in the following decade’s production figures, not its own. Neither point diminishes the case for the programme. Both argue for measuring it correctly: the honest interim metrics are square kilometres of new seismic acquired, wells spudded in frontier basins, and third-party capital committed alongside the state’s — not barrels, which will not arrive for years.
