Context: Oil India Ltd (OIL) has announced the discovery of natural gas in the Andaman Shallow Offshore Block.

  • This marks the first reported hydrocarbon find in the region, potentially reducing India’s heavy import dependence on oil and gas.

About India Discovers Natural Gas near Andaman Island:

What it is?

  • Natural gas reserves identified in Vijayapuram-2 exploratory well under the Open Acreage Licensing Policy (OALP).
  • Gas samples confirmed 87% methane content, showing commercial potential after further testing.

Located in:

  • Offshore block 9.20 nautical miles (17 km) from the Andaman east coast.
  • Water depth: 295 metres, drilling depth: 2,650 metres.

Key Features of Andaman Islands:

  • Geography: Archipelago of 300+ islands forming part of Andaman & Nicobar Union Territory, located in the Indian Ocean about 1,370 km east of mainland India.
