India has achieved a significant milestone in its search for energy resources. On September 27, 2025, Union Petroleum Minister Hardeep Singh Puri announced natural gas discoveries in the Andaman Sea with 87% methane. This marks the first-ever confirmation of hydrocarbons in this area, and experts believe it could help the nation on the road to energy independence.
The announcement has generated a lot of excitement due to prospective benefits for both India’s economy and its future energy security. ONGC and OIL are leading exploration efforts, with the oil discovery of 2 lakh crore litres potentially forthcoming from the same region.
The find was made in the Sri Vijayapuram-2 well about 17 kilometres off the east coast of the Andaman Islands. The well was drilled in water, which is now nearly 295 meters high, and was completed at a final depth of 2,650 meters below sea level. In the course of testing, scientists found traces of natural gas between 2,212 and 2,250 meters. In addition, gas flares confirmed the hydrocarbon flow.
The site gas samples were sent to Kakinada for testing. The laboratory reports showed that the gas contained nearly 87% methane, which is a high-quality fuel. However, as officials clarify, such evidence only proves the existence of gas and not the size and commercial potential of reserves available after being studied in detail.
Minister Puri clearly said that the find is an “ocean of energy opportunities” for India. He expressed how geologists have long thought that the Andaman basin has immense potential for hydrocarbons, the reason being that similar reserves are present in neighbouring states extending from Myanmar to Indonesia. The discovery has now confirmed the belief.
This discovery comes at an unexpected moment for India. Currently, the economy is burdened with almost 50% natural gas imports, which limits the use of gas and simultaneously makes India dependent on global price changes. If Andaman reserves prove enough, India would not rely on imports and continue developing domestic production. Also, it will complement the government’s approach toward having a bigger part of natural gas in India’s energy mix, approximating 15% by 2030.
The discovery also complements the government’s new initiatives for promoting deep-water exploration. Prime Minister Narendra Modi, last week, launched the National Deep Water Exploration Mission, best known as Samudra Manthan. This mission intends to fast-track exploration of offshore areas and tap undetected resources beneath the sea. The Andaman success could persuade people to invest more in such projects.
Geologically, this basin is a part of the bigger Bengal-Arakan sedimentary system. The sedimentary system spans various countries and is already known to be hydrocarbon-producing. For decades, Indian scientists have estimated that the Andaman region could also have oil and gas. Now, with this discovery, India has real proof of its potential.
The net economic impact of this discovery could be huge. Deepwater drilling is very expensive and technologically complex, demanding advanced and skilled know-how. Second, the Andaman fragile ecosystem will need strong environmental protection. This biodiversity-rich area requires that no diversity of marine life or local communities be harmed to develop any energy project.
Another issue is infrastructure. The Andaman Islands are far away from mainland India. This will take the company and the government a long time and lots of investment to set up pipelines or transport facilities. The government and companies will also have to very carefully plan the safe and economical way to bring the gas to markets.
The discovery, however, has provided a huge boost for India’s confidence in offshore exploration. Scientists will be carrying out more tests, seismic studies, and reservoir analysis to estimate total gas within the forthcoming months. It is also possible that more wells will be drilled to explore the full extent of the reserves. When all results are positive, India would then move into the development-production stage.
In fact, the discovery of natural gas in the Andaman Sea represents a historical moment in India’s energy history. It has been proven that untapped resources lie within offshore basins in the country, while continued exploration will pay huge dividends. There is a long way to go before extraction begins, but this find opens new doors for India’s dream of energy self-reliance. With planning, state-of-the-art technology, and stronger environmental safeguards, the Andaman discovery could become a backbone for securing India’s energy future.
