| Category | Details |
|---|---|
| Event | First geothermal production well drilled in Dirang, West Kameng district, Arunachal Pradesh |
| Location | Dirang, West Kameng district, Arunachal Pradesh |
| Project Lead | Centre for Earth Sciences and Himalayan Studies (CESHS) |
| Support | Ministry of Earth Sciences and Government of Arunachal Pradesh |
| International Partners | Norwegian Geotechnical Institute (NGI), Oslo, Geotropy ehf (Iceland), Guwahati Boring Service (GBS) |
| Background | Based on two years of geochemical and structural surveys in western Arunachal. Dirang identified as a medium-to-high enthalpy geothermal zone with estimated reservoir temperature of 115°C. |
| Geological Features | Quartzite overlying schist near the Main Central Thrust (MCT) -- favorable for geothermal activity. |
| Potential Applications | Eco-friendly fruit, nut, and meat drying, space heating for high-altitude homes and institutions, controlled-atmosphere storage systems for agriculture, geothermal-powered city infrastructure in future. |
| Significance | First geothermal production well in the Northeast, pioneers the use of clean and renewable energy in the Himalayas, offers a sustainable heating solution for cold regions, boosts agro-economy. |
