If it finds nothing, the State absorbs the loss. What is the Samudra Manthan scheme all about? | Explained storyline 1 That recovery clause, set out in newly issued operational guidelines, is the scheme's central bargain — the government carries early geological risk and keeps a claim on any upside. ONGC to infuse ₹1 lakh crore for deepwater exploration: Chairman ONGC to infuse ₹1 lakh crore for deepwater exploration: Chairman ONGC to infuse ₹1 lakh crore for deepwater exploration: Chairman storyline 1 The guidelines say recovery starts after seven years of commercial production, or once the operator has recouped 50% of its exploration and development costs, whichever comes first.

Repayment comes in annual instalments, with no inflation indexation. The scheme will support 60 wells in deepwater (deeper than 400 metres) and ultra-deepwater (deeper than 1,500 metres) areas. Of these, 56 exploratory wells get up to 50% of actual cost, capped at ₹675 crore per well, the guidelines said, adding that four stratigraphic wells, drilled to study rock layers, get up to 100%, capped at ₹1,350 crore each.

Only state-run firms or consortia they lead can apply. Payment is milestone-based — 40% when drilling reaches 40% of the approved depth and 60% on completion and approval of the well report. By these caps, well support alone could reach ₹43,200 crore, about half the total outlay. The guidelines did not give a component-wise budget split. The guidelines also lay out a strict eligibility test.

Only blocks or areas awarded under the Revenue Sharing Contract regime qualify.

Production-sharing and coal-bed methane blocks, awarded prior to that, are excluded unless the government notifies otherwise. Importantly, only exploration wells or wells drilled to find new resources qualify for the grant.

Development wells, which are drilled to bring an already discovered resource into production, are not covered. Sidetrack well costs are also not covered. The scheme aims to cut India's heavy reliance on imported hydrocarbons. The guidelines say it will run through FY2030-31, with FY2026-27 as a preparatory year and spending in FY 2027-28 to FY2030-31 as Phase I. Prime Minister Narendra Modi announced the scheme in his August 15, 2025 Independence Day speech, saying India wants "to work in a mission mode towards finding oil and gas reserves under the sea".

Petroleum Secretary Neeraj Mittal, in the preface to the guidelines, called the scheme "the most ambitious upstream oil and gas intervention undertaken in recent times" and said it could add "more than 600 million tonnes of oil equivalent" to India's reserves. The government financial support is intended to reduce the upfront burden of exploration while allowing the State to recoup its investment when a project succeeds.

Operators will still bear costs above the support caps and face the risk of losing eligibility if they fail to meet work commitments or pay penalties instead of completing committed drilling.

Eligible items include subsea manifolds, trunk pipelines, central processing platforms and shared floating production units. Support is initially planned for the Mahanadi basin, with token funding for Kutch. Discoveries in basins such as Mahanadi and Kutch "remain stranded or commercially unviable on a standalone basis", the guidelines say, because none alone can justify the cost of pipelines and processing facilities.

Viability gap funding would support shared infrastructure for two or more field developments, including subsea manifolds, trunk pipelines, central processing platforms and shared floating production units. A joint venture or special-purpose vehicle of participating operators would own and build the hub. Rivals must agree on equity, ownership, and capacity commitments before construction starts.

The hub must operate on "fair and non-discriminatory access" under the PNG Rules, with unused capacity offered to others. Funding comes in four equal 25% tranches tied to physical progress of 25%, 50%, and 75%, and then commissioning. The first tranche requires financial closure, executed construction contracts, and operator commitment agreements. Receiving the money does not reduce operators' safety, environmental or decommissioning obligations.
