A fresh natural gas discovery in the Andaman Sea has renewed hopes of unlocking a major domestic energy source for India. State-run Oil India Limited (OIL) has confirmed the presence of natural gas in an exploratory well drilled off the Andaman Islands, a development that the government sees as an encouraging sign for the country's offshore exploration programme.
The discovery was made at the "Sri Vijayapuram-3" well, located about 15 kilometres from the eastern coast of the Andaman Islands. Union Petroleum and Natural Gas Minister Hardeep Singh Puri described the find as an "ocean of energy opportunities" and said initial testing had established the presence of natural gas through continuous flaring.
The development comes as India intensifies efforts to discover new oil and gas reserves under the National Deep Water Exploration Mission, also known as the "Samudra Manthan Mission."
Why Is Andaman Gas Discovery Important?
The significance of the discovery goes beyond a single well. For years, geologists and policymakers have believed that the Andaman Basin could hold large hydrocarbon reserves. The latest finding strengthens that belief and adds to evidence that the region may emerge as one of India's key energy frontiers.
According to the government, hydrocarbons have now been reported in two of the three exploratory wells drilled by Oil India in the current Andaman Basin campaign. While the exact size of the newly discovered reserves remains unknown, the result is being viewed as a positive indicator for future exploration.
"An ocean of energy opportunities reinforced in the Andaman Sea! Very happy to report the presence of natural gas in Sri Vijayapuram-3 an exploratory well drilled by Oil India Ltd. 15 km off the east coast of the Andaman Islands at a water depth of 355 meters. Initial production testing of the well at the depth of 1900 plus meters in the Eocene formation has established the presence of natural gas through continuous flaring," Puri said in a post on X.
Can It Reduce India's Dependence on Energy Imports?
That is the big question, but the answer is not immediate. India remains heavily dependent on imported energy. More than 85 per cent of the country's crude oil requirement is met through imports, while a substantial share of natural gas demand is also fulfilled through imported liquefied natural gas (LNG).
If future drilling confirms commercially viable reserves in the Andaman Basin, the discovery could help reduce some of that dependence. Increased domestic production would strengthen energy security and reduce exposure to fluctuations in global fuel markets.
However, experts caution that a discovery is only the first step. Before any gas reaches consumers, extensive testing, reserve estimation, infrastructure development and commercial approvals will be required.
Could Andaman Become India's Guyana?
The Andaman Basin has often been compared with Guyana, where major offshore discoveries transformed the country's energy sector. Union Minister Puri has repeatedly expressed confidence about the basin's long-term prospects.
“It’s only a matter of time before we find a big Guyana in the Andaman Sea,” he had said earlier while referring to ongoing exploration efforts.
Industry estimates cited in connection with seismic surveys suggest the basin could hold between 307 and 370 million metric tons of oil-equivalent hydrocarbons. These are preliminary projections and not confirmed reserves, but they have added to expectations surrounding the region.
The Road From Discovery to Production Is Long
Despite the excitement, commercial production remains years away. Oil India is currently carrying out gas sampling, calorific value assessment and isotope studies to understand the nature and origin of the gas. More exploratory drilling will be needed to determine whether the discovery can support large-scale commercial operations.
Experts note that offshore projects typically take many years to move from discovery to production. Additional investments, technical studies and partnerships with global deepwater specialists will be necessary before the basin's full potential becomes clear.
The government has already indicated that exploration activities will continue in collaboration with international deepwater exploration experts.
A Key Test for the Samudra Manthan Mission
The discovery also serves as an early boost for the government's National Deep Water Exploration Mission. Announced by Prime Minister Narendra Modi, the initiative aims to accelerate exploration in India's offshore basins and unlock untapped hydrocarbon resources.
"We are now also heading towards 'Samudra Manthan.' Taking this forward, we aim to operate in Mission Mode to explore the oil and gas reserves in the sea. So, India is about to launch the National Deep Water Exploration Mission," PM Modi had said while announcing the initiative.
For now, the Andaman discovery does not change India's energy equation overnight. But it offers another clue that the waters around the islands may hold significant untapped resources. Whether that translates into lower import dependence will depend on what future drilling reveals in the years ahead. READ ALSO: Oil India reports natural gas presence in second Andaman offshore well
