One more restriction worth noting. Diploma engineering, BBA, BCA, BA, BCom and BSc undergraduate students are not eligible for this internship.
The Indian Oil Guwahati Refinery Internship mainly targets core and infrastructure branches. Eligible branches include:
Refinery internships tend to be most valuable for mechanical, chemical and instrumentation students because of the exposure to plant operations.
The internship duration can vary depending on the training module selected.
For the 2026 summer cycle, the refinery had three joining batches:
Students can choose their preferred batch while applying. Final confirmation is sent by email if you get selected.
The application process involves a few mandatory documents. These must be uploaded during registration and later sent physically.
You can download the official formats here:
The NOC is especially important. It must be printed on your college letterhead and signed by the Head of Department. Without that approval, the refinery will reject the application.
The process has both online and offline steps. Follow them carefully.
