Oil and Natural Gas Corporation (ONGC) Geologist and Engineer Recruitment 2026

Oil and Natural Gas Corporation (ONGC) is India's largest Maharatna energy company, producing over 73% of India's crude oil and 57% of its natural gas, with operations spread across 18 countries. ONGC currently employs around 22,600 professionals and is investing heavily in natural gas, renewables, and new energy technologies as it grows beyond its traditional oil and gas business. This recruitment drive is for Geologists and Engineers at E1 Level — an entry-level officer grade that puts fresh graduates directly on ONGC's long-term career track. Government job security combined with a Maharatna PSU's scale makes this one of the most sought-after openings for engineering and geoscience graduates every year.

ONGC describes this hiring push as a launchpad for ambition, innovation, and professional growth, not just an entry-level job. As an E1-level officer, you would join a large, diverse workforce spread across ONGC's exploration blocks, refineries, and research institutes — from onshore fields in Assam and Gujarat to offshore platforms in Mumbai High. ONGC also runs its own training academies, including the Institute of Drilling and Well Engineering (IDWE) and KDMIPE for geoscientists, so new recruits get structured, hands-on skill development early in their careers.
