Churning the Ocean: A ₹84,084-Crore Bet That India's Missing Oil Lies Offshore
Import dependence hit a record 88.7 per cent while domestic output kept falling — Samudra Manthan is an attempt to buy back exploration acreage India never properly surveyed
What happened
An aspirant should read this as a wager on information, not on oil. India's offshore sedimentary basins are among the world's least surveyed, and the scheme's largest early component is seismic data acquisition rather than drilling. Exploration policy has failed for two decades not mainly because the rocks were poor but because nobody knew enough about them to bid confidently, and that is the deficit this money targets.
What Samudra Manthan actually funds
| Component | Bottleneck it targets |
|---|---|
| Large-scale seismic acquisition, processing and interpretation | Investors cannot evaluate acreage they have no data on |
| Deepwater and ultra-deepwater exploratory drilling | High per-well cost deters private risk-taking in unproven zones |
| Scientific drilling in frontier basins | Basins with little or no drilling history remain unassessed |
| Common production and evacuation infrastructure | Small discoveries cannot justify dedicated platforms and pipelines |
| Integrated Oil and Gas Manufacturing and Services Zone | Dependence on a few international offshore services contractors |
India's sedimentary basins are classified by exploration maturity into categories from Category I, which have established commercial production, down to frontier basins with little or no drilling.
●The bulk of India's producing acreage lies in a handful of Category I basins, notably Mumbai Offshore, Krishna-Godavari, Cauvery, Assam-Arakan and Cambay, while very large offshore areas remain barely explored.
●Upstream policy has moved through successive regimes: the New Exploration Licensing Policy from 1999, which awarded blocks through competitive bidding on work programme and profit share; the Hydrocarbon Exploration and Licensing Policy from 2016, which introduced a uniform licence for all hydrocarbons, revenue sharing instead of profit sharing, and marketing and pricing freedom; and the Open Acreage Licensing Programme, which lets investors themselves nominate blocks of interest from a National Data Repository rather than waiting for government-defined rounds.
●Samudra Manthan sits upstream of all of this, funding the data and infrastructure that make bidding possible.
The binding constraint on Indian exploration has been information and infrastructure, not licensing terms — which is why a data-and-drilling scheme follows two decades of licensing reform.
◎ In Simple Words
Most of the oil and gas India uses is bought from other countries, and the amount we produce at home keeps falling. A lot of the sea floor around India has never been properly scanned, so companies do not know where it is worth drilling. The government has set aside a very large sum to scan the seabed, drill test wells in deep water, and build shared equipment so exploring becomes less risky.

Under the Hydrocarbon Exploration and Licensing Policy (HELP) introduced in 2016, which of the following was a key change from the earlier New Exploration Licensing Policy?
Mains Practice Questions
"India's exploration deficit is a data deficit before it is a geological one." Critically examine this claim in the light of the Samudra Manthan scheme.
Evaluate whether public expenditure of ₹84,084 crore on offshore hydrocarbon exploration is consistent with India's net-zero-by-2070 commitment.
Discuss how shared offshore production and evacuation infrastructure changes the commercial viability of marginal hydrocarbon discoveries, and what this implies for exploration policy.
Frequently Asked
· People also askWhat is the Samudra Manthan scheme?
A Central Sector Scheme of the Ministry of Petroleum and Natural Gas, approved by the Union Cabinet on 31 July 2026 with an outlay of ₹84,084 crore for implementation up to FY 2030-31. It funds offshore seismic surveys, deepwater exploratory drilling, frontier-basin scientific drilling and shared offshore infrastructure.
GS3 · EconomyThe Government expects it to catalyse reserve accretion of over 600 million metric tons of oil equivalent. The name invokes the churning of the ocean from Hindu mythology, framed by the Prime Minister as a modern-day Samudra Manthan.

How dependent is India on imported crude oil?
India's crude oil import dependence reached a record 88.7 per cent in 2025-26, according to Petroleum Planning and Analysis Cell data. Domestic crude production fell from 29.7 million metric tonnes in 2021-22 to 28 MMT in 2025-26, largely because of ageing oilfields.
GS3 · Energy securityGas tells a similar story: LNG imports now supply about 50.1 per cent of India's total gas availability, against 40.7 per cent a decade earlier. High import dependence transmits crude price shocks into the trade deficit, the rupee and domestic inflation.

How is Samudra Manthan different from the Deep Ocean Mission?
Samudra Manthan is a hydrocarbon exploration scheme under the Ministry of Petroleum and Natural Gas, targeting offshore oil and gas. The Deep Ocean Mission is run by the Ministry of Earth Sciences and concerns deep-sea minerals such as polymetallic nodules, marine biodiversity and crewed submersible technology.
GS3 · SchemesThe two are frequently confused because both are ocean-facing national missions. The distinguishing test is the resource: hydrocarbons under Petroleum and Natural Gas, seabed minerals and marine science under Earth Sciences.

Why does the government fund seismic data instead of leaving it to companies?
Because seismic data has public-good characteristics: it is expensive to acquire, cheap to copy, and worth far more to the sector collectively than to any single explorer. Left to private incentives it is systematically under-produced, so companies cannot evaluate acreage well enough to bid confidently.
GS3 · ConceptPublicly funding surveys and lodging results in the National Data Repository transfers geological risk from bidder to state. Several petroleum-producing countries fund regional surveys on the same logic.

What are HELP and OALP in India's exploration policy?
The Hydrocarbon Exploration and Licensing Policy, introduced in 2016, replaced profit sharing with revenue sharing, created a uniform licence covering all hydrocarbons and granted marketing and pricing freedom. The Open Acreage Licensing Programme lets investors nominate blocks of interest from the National Data Repository rather than awaiting government-defined rounds.
GS3 · PolicyBoth replaced the New Exploration Licensing Policy of 1999. Revenue sharing removes the government's need to audit contractor costs, which had been a persistent source of dispute under profit-sharing contracts.

Does this scheme conflict with India's net-zero commitment?
There is a genuine tension. Committing ₹84,084 crore to hydrocarbon exploration through FY 2030-31 sits alongside India's net-zero-by-2070 target and rapid renewable expansion, and carries stranded-asset risk in late-life fossil infrastructure.
GS3 · EnvironmentThe Government's reconciliation is that oil and gas demand will persist through the transition, so substituting imports with domestic production reduces external vulnerability without increasing total consumption. Whether that holds depends on how quickly transport electrifies.
