The Samudra Manthan scheme is a Rs 84,084 crore government plan to share the cost of searching for oil and gas in India's deep offshore waters. According to reports, the idea is to cut the financial risk that keeps companies from drilling in difficult, expensive locations. The long-term aim is to make India less dependent on imported crude.
It will not lower your petrol price next month. It is a slow, high-risk, high-cost bet that pays off, if at all, over many years. This guide explains what is known, what is not yet clear, and how to read the news that follows.
Key takeaways
- Reports say the government will share deepwater oil and gas exploration costs under a Rs 84,084 crore scheme named Samudra Manthan.
- Deepwater drilling is costly and often fails, so cost sharing mainly reduces the risk for the companies that drill.
- The scheme is about energy security over years, not about quick relief in fuel prices.
- Key details, such as the share the government will bear and the eligibility rules, should be checked in the official notification once available.
What is the Samudra Manthan scheme?
The name comes from the Hindu legend of churning the ocean to draw out treasure. Here, the treasure is crude oil and natural gas under the seabed. The scheme was reported by outlets including The New Indian Express, KNN India and Rediff MoneyWiz as a government programme to support deepwater exploration with a total outlay of Rs 84,084 crore.
At current exchange rates, that is roughly US$9 to 10 billion, though the dollar figure moves with the rupee. It is a large sum, but deepwater exploration is one of the most expensive activities in the energy business, so the money can be used up faster than it sounds.
What we know and what we do not
The reports we have seen confirm the headline numbers and the cost-sharing idea. They do not, in the material we reviewed, spell out the finer rules. Until the official notification is public, treat anything beyond the basics as unconfirmed.

How does deepwater oil exploration work?
"Deepwater" usually means the seabed lies far below the surface, commonly beyond about 400 metres of water, with "ultra-deepwater" going deeper still. The definition varies by country and by policy. The process has the same broad steps everywhere.
- Survey. Ships send sound waves into the seabed and record the echoes. Specialists turn these into 3D maps of rock layers that might trap oil or gas.
- Choose a spot. Geologists rank locations by how likely they are to hold hydrocarbons. Even the best-ranked spot is a gamble.
- Drill an exploration well. A drillship or a floating rig drills through the water and then the rock. This is the costly step, because the rigs are specialised and rented at high daily rates.
- Test the discovery. If oil or gas turns up, more wells measure how much is there and whether it can be extracted at a profit.
- Develop and produce. Underwater equipment, pipelines and a floating platform are built. This can take several years after the discovery.
Most exploration wells in the world do not lead to commercial production. That is the central reason a scheme like this exists.
Why would the government share the cost?
A private or public company that drills a deepwater well pays the full bill whether or not it finds anything. If the well is dry, the money is gone. When the odds of failure are high and the bills run into hundreds of crores per well, many companies prefer safer projects elsewhere.
Cost sharing changes that arithmetic. The state takes on part of the early risk, hoping that a few discoveries will repay the country through energy supply, tax and royalty revenue.
A worked example (illustrative numbers only)
The numbers below are invented to show the logic. They are not the scheme's actual terms.
- Assume one deepwater exploration well costs Rs 600 crore.
- Assume a company must drill 4 wells to expect one success. Total spend: 4 × Rs 600 crore = Rs 2,400 crore.
- Without any support, the company carries all Rs 2,400 crore, and three of the four wells earn nothing.
- Now suppose the government covered 30% of exploration costs. Its share would be 0.30 × Rs 2,400 crore = Rs 720 crore.
- The company would then bear Rs 2,400 crore − Rs 720 crore = Rs 1,680 crore.
The company still carries a lot of risk, but its downside is smaller, so a marginal project can start to look worth trying. For the government, the question is whether the discovery, when it comes, is worth more than the money it put in. That is not guaranteed.
What does it mean for India's oil imports and energy security?
India imports most of the crude oil it uses. The commonly cited figure is around 85% of requirements, and the exact share changes from year to year. That makes the country exposed to global price swings, shipping disruptions and currency movements, since oil is bought in dollars.
Domestic production has been flat or slowly falling for years, while consumption has grown with vehicles, industry and cooking fuel. New fields in deep waters are one of the few places where large undiscovered volumes might still exist, which is why the government is targeting them.
Here is the honest limit. Even a big discovery will not remove import dependence. It could trim the gap, and natural gas finds could support power, fertiliser and city gas supply. Anything more depends on how much is found and how fast it is brought to market.
Myth vs fact
Myth: More deepwater drilling will make petrol and diesel cheaper soon.
Fact: Fuel prices depend heavily on international crude prices, refining costs and taxes. Domestic crude is generally priced in line with global benchmarks, so new output does not automatically mean cheaper fuel. It mainly improves supply security and the import bill.
Myth: A Rs 84,084 crore scheme means that much oil money is coming.
Fact: It is a support budget for exploration. Oil only arrives if wells strike hydrocarbons, and then only after development work.

Who gains from the scheme?
Oil and gas companies
Explorers, including state-owned and private firms, gain lower risk on early wells. Foreign firms with deepwater experience may find India more attractive, though participation rules have not been confirmed in the notes we reviewed.
Coastal states
States on the east and west coasts could see port activity, supply bases, and royalty or tax flows if production starts. Onshore terminals and pipelines would also bring local construction work. These benefits depend on where discoveries happen.
Jobs and suppliers
Offshore work employs geologists, drilling engineers, marine crew, welders, divers, logistics staff and equipment makers. Smaller businesses often supply catering, transport, fabrication, safety gear and maintenance services. If you run a small firm, registering properly helps in tenders, and our guide to Udyam registration and the new MSME limits explains the basics.
Job numbers should be treated cautiously. Deepwater projects are capital-heavy and use fewer workers than, for example, factories. Compare this with sectors where hiring scales more directly, such as the one in our piece on India's semiconductor industry and jobs.
Is there a Gujarat angle?
Gujarat has long been central to India's energy chain. It has oil and gas history in the Cambay and Kutch-Saurashtra regions, a long coastline, major refining capacity at Jamnagar, and LNG import terminals such as Dahej. The state's ports and industrial clusters are well placed to handle supplies and services for offshore operations in the Arabian Sea.
Whether Gujarat benefits directly depends on where blocks are offered and where the discoveries are. The state is more likely to gain from processing, shipping and supply work than from new wells off its own coast, but that is an expectation, not a confirmed outcome.
What are the risks and criticisms?
- Dry wells. Public money could be spent on wells that find nothing.
- Long timelines. Discovery to production can take many years, and energy needs or technology may change in that time.
- Environmental concerns. Offshore drilling carries spill risks and affects marine life and fishing communities. Approvals and safety rules matter.
- Opportunity cost. Money spent here is money not spent on renewables, storage or efficiency. Many analysts argue India needs both, because oil and gas demand is still growing.
A balanced reading is that the scheme is a reasonable attempt to improve energy security, provided the cost-sharing terms are transparent and tied to actual drilling and results.
What should you watch next?
- The official notification: the government's cost share, eligible blocks and the scheme's duration.
- Which companies apply, and whether any foreign firms with deepwater experience take part.
- Auction or licensing rounds for new blocks.
- Drilling announcements and the first reported discoveries.
- Environmental clearances and any objections from coastal communities.
- Domestic crude and gas production figures in the coming years.
Frequently asked questions
What is the Samudra Manthan scheme?
It is a government scheme, with a reported outlay of Rs 84,084 crore, to share the costs of deepwater oil and gas exploration. Its purpose is to encourage drilling in deep offshore areas and reduce India's reliance on imports over time.
Will the scheme reduce petrol and diesel prices?
Not directly. Fuel prices depend on global crude rates, taxes and refining costs. New domestic supply mainly helps energy security and may reduce the import bill if large volumes are found.
How much of the cost will the government bear?
The material we reviewed does not state the share. Check the official notification or a PIB release before relying on any percentage you see quoted.
How long before we see any oil from deepwater blocks?
Exploration alone can take a few years, and development after a discovery often takes several more. So production, if any, is generally a long-term outcome rather than something visible soon.
Does this mean India will stop importing oil?
No. India's demand is far larger than what any single scheme could replace. The realistic goal is to lower the share that must be imported, not to end imports.
Bottom line
The Samudra Manthan scheme is a large, risk-sharing bet that India's deep waters hold usable oil and gas. Its success will depend on the fine print and, above all, on what the drills find. For now, read the official notification on pib.gov.in, note the cost-sharing terms, and judge later headlines by actual discoveries rather than outlay figures.
