Oil India Ltd has announced the discovery of natural gas in the Vijayapuram-3 exploratory well, marking its second successful hydrocarbon find in the Andaman offshore basin. The company reported this finding to the stock exchanges on Friday, emphasising the potential for the region to become a significant source of hydrocarbons for India. The well is part of the ongoing exploration efforts in the Andaman Shallow Offshore Block AN-OSHP-20181.

This well, located approximately 15 kilometres from the east coast of the Andaman Islands, was drilled to a depth of 355 metres under the Open Acreage Licensing Policy (OALP). Initial results show that the geological formations in the area may hold substantial hydrocarbon potential, thus encouraging future exploration.

Preliminary assessments indicate a functioning hydrocarbon system in the region, with the well exhibiting an immediate pressure build-up following perforation. Continuous flaring during initial production testing confirmed the presence of gas. The company is currently conducting further analyses, including gas sampling and isotope studies, to ascertain the gas’s composition and origin.

Significance of the Hydrocarbon Discoveries

The discovery of natural gas in the Vijayapuram-3 well adds to the findings from the Vijayapuram-2 well, which reported hydrocarbons in September 2025. With two successful wells out of three drilled, there is an increased optimism regarding the presence of significant natural gas resources in the Andaman offshore basin.

While determining the commercial viability of these reserves remains essential, the evidence suggests that the geological conditions conducive to oil and gas accumulation exist in the area. According to Oil India, these findings support the possibility of hydrocarbon source systems, migration pathways, and accumulations in the prospect area.

Following the earlier discovery, Oil India initiated an appraisal programme to further analyse the resource potential of the block. This effort included reprocessing existing 2D seismic data and acquiring an additional 600 square kilometres of 3D seismic data, with processing and interpretation currently in progress.

Future Exploration and Energy Security

Interest in the Andaman offshore basin has been growing due to its geological similarities with other hydrocarbon-rich areas in Southeast Asia. Energy companies and policymakers are increasingly recognising its potential as a crucial frontier for oil and gas exploration. While discoveries do not inherently guarantee commercial production, multiple hydrocarbon encounters enhance confidence in the area’s long-term prospects.

For India, the advancement of domestic gas resources could play a significant role in improving energy security while reducing reliance on crude oil and natural gas imports. Oil India has committed to keeping its stakeholders updated on the progress of exploration activities within the Andaman offshore basin.

On Friday, shares of Oil India traded at Rs 488.95, maintaining stability despite experiencing a rise of over 14 per cent in value so far this year. As exploration efforts continue, the outcomes of these developments will be closely monitored by investors and energy experts alike.
