The well is called Sri Vijayapuram-3. It sits 15 kilometres off the east coast of the Andaman Islands, at a water depth that would have been technically inaccessible for Indian exploration just a decade ago. And when Oil India drilled into it earlier this week, it found what geologists had long suspected was there: natural gas.

Union Petroleum Minister Hardeep Singh Puri confirmed the discovery on June 5, 2026, describing it as reinforcing an "ocean of energy opportunities" in the Andaman Sea.

Laboratory analysis of gas samples showed methane content of around 87 per cent — confirming the hydrocarbon discovery as commercially significant in composition, even if commercial viability at scale is yet to be established.

This is the second discovery in the Andaman basin in recent months. An earlier find at Sri Vijayapuram-2, approximately 17 kilometres from the shoreline at a water depth of 295 metres, had already established gas presence with methane content tested at 87 per cent at Kakinada. Two discoveries in the same basin, in quick succession — that is not luck. That is geological confirmation of a hypothesis India has been testing for years.

THE BIGGER PICTURE: WHY THE ANDAMAN BASIN MATTERS

The Andaman basin lies within a larger petroleum-rich belt stretching from Myanmar in the north to Indonesia in the south — a region where several commercially successful gas fields have already been developed. India's geology, in this specific basin, mirrors proven producing territory on both sides of it. The question was never really whether hydrocarbons existed here. It was whether India had the technology, the policy framework, and the institutional will to find them.

The opening of nearly one million square kilometres of erstwhile "No-Go" offshore areas in 2022 was the policy unlock that made this possible. Since 2015, exploration companies operating in India have reported 172 hydrocarbon discoveries, including 62 in offshore areas. The Andaman finds are the most strategically significant of the recent batch — both because of the basin's scale potential and because of where it sits geopolitically.

THE EAST COAST ESCALATION

Building on the Andaman momentum, the government has now launched a broader exploration drive across India's east coast — covering the Krishna-Godavari Basin, the Mahanadi offshore, and the Cauvery Basin, in addition to the Andaman zone.

While the Andaman discovery is still at the stage of confirming hydrocarbon presence — with commercial production potentially a decade away — the find is already reshaping confidence in India's entire offshore exploration programme. The Andaman discovery changes the risk perception of the basin. Once a basin is proven — once the hydrocarbons are demonstrably there — the economics of further exploration improve dramatically. International deepwater specialists become more willing to commit capital. Farm-in agreements become easier to negotiate. The entire exploration flywheel accelerates.

Minister Puri has stated that under the deepwater mission announced by Prime Minister Modi, a large number of deepwater exploration wells are planned across India's offshore basins — with a specific focus on coordinating with global deepwater exploration experts to accelerate the programme.

India imports over 85% of its crude oil and a significant portion of its LNG requirements — a dependence that costs hundreds of billions of rupees in foreign exchange annually and that represents a structural strategic vulnerability. Every discovery in the Andaman basin, every block awarded on the east coast, and every deepwater well successfully drilled is a step toward a future where that dependence is meaningfully lower.

Two wells. Two discoveries. The east coast hunt has begun in earnest.
