Oil India Limited has opened a specialist engagement for one Domain Expert in Critical Minerals under Advertisement No. HRAQ/CONT-EX-B/26-315 dated 6 November 2026. The opportunity is designed for a highly experienced retired geoscience professional who can guide OIL's critical-mineral exploration work, including activities connected with the Phop block in Arunachal Pradesh and other strategic mineral projects. The selected expert will report at OIL's Centre of Excellence for Energy Studies in Guwahati and may be required to travel for project work. This is not a regular salaried post: the engagement is on an on-call contract basis for two years, with an honorarium linked to the retired officer's former level or grade. The notified rate ranges from ₹10,000 to ₹20,000 per day, and the expert may be engaged for up to 100 days in a year. At a basic level, candidates need a postgraduate qualification in Geology or Applied Geology together with extensive senior-level experience in a Government mining or geoscientific organisation. For the right candidate, this is a specialist advisory role rather than a conventional vacancy, with work tied directly to strategic mineral exploration decisions. Applications can be submitted by post or email and must reach OIL by 23:59 hours on 5 December 2026.
