Apprentice (Various Trades) – ONGC
Ongcapprentices
About the role
Oil and Natural Gas Corporation Limited (ONGC) is India’s flagship energy major and a Maharatna Central Public Sector Enterprise. With a legacy spanning over six decades, ONGC is the country’s largest producer of crude oil and natural gas, operating across the upstream value chain – from exploration and drilling to production and processing. The corporation’s vision is to fuel the nation’s growth while championing sustainable practices, cutting‑edge technology, and a robust safety culture.
As part of its Skill Building Initiative, ONGC runs a nationwide apprenticeship programme across 24 work centres, offering fresh talent a hands‑on platform to learn industry‑relevant skills under seasoned professionals.
The Apprentice role is designed for recent graduates, diploma holders, and ITI pass-outs who wish to start their career in the oil and gas sector. Apprentices will be posted at one of the designated locations – Delhi, Mumbai, Vadodara, Sivasagar or Chennai – based on merit and availability. Under the mentorship of senior engineers and technicians, apprentices will rotate through core operational units, gaining exposure to drilling operations, pipeline maintenance, instrumentation, safety protocols, and basic project management.
The programme spans 12 months, during which the apprentice receives a monthly stipend, on‑the‑job training, and a certificate of completion that is recognized nationwide.
Key responsibilities include
- Assisting senior technicians in routine maintenance and inspection of equipment.
- Supporting drilling and production teams with data collection and basic analysis.
- Learning and adhering to safety standards, emergency response procedures, and environmental guidelines.
- Participating in daily briefings, reporting observations, and suggesting process improvements.
- Conducting basic troubleshooting of mechanical and electrical systems under supervision.
- Maintaining accurate logs of work performed, materials used, and time spent.
- Helping in the preparation of work permits and compliance documentation.
- Engaging in on‑site training sessions, workshops, and safety drills.
- Collaborating with cross‑functional teams to understand the end‑to‑end workflow of oil and gas operations.
- Completing periodic assessments and presenting learning outcomes to mentors.
The technical stack is practical rather than software‑centric, focusing on tools such as hand‑held diagnostic devices, basic PLC interfaces, MS Office for reporting, and industry‑standard safety equipment. Growth path for apprentices is clearly defined – high performers may be offered a Technician position or be considered for entry‑level engineering roles after successfully clearing the internal assessment and meeting eligibility criteria. The apprenticeship experience also enhances employability across the broader energy sector, given ONGC’s reputation for rigorous training and adherence to global standards.
Why join ONGC as an apprentice? You will be part of a prestigious organization that values skill development, offers exposure to large‑scale projects, and provides a structured learning environment. The programme not only equips you with technical know‑how but also instills a safety‑first mindset, teamwork, and problem‑solving abilities that are highly prized in the industry.
Moreover, the stipend, certification, and potential for future employment make this an attractive launchpad for a long‑term career in energy.
